1 MultiCatch Shell Catcher Instuctions For 12 Gauge Beretta AL391

MultiCatchTM Shell Catcher Instuctions
For 12 Gauge Beretta AL391 Urika, Urika 2, Teknys, 390 and 3901 Model Shotguns
Safety is always first and foremost in the use and operation of firearms. Before installing
the MultiCatchTM you must be fully familiar with the safe operation of your gun and all
of its features. This model of the MultiCatchTM is only for use on 12 gauge Beretta
AL391 Urika, Urika 2, Teknys, 390 and 3901 model shotguns. This model of the
MultiCatchTM does not fit the Beretta A391 Extrema or Extrema 2 guns. It is only for use
with 2 ¾ inch plastic shotshells which are sized or re-sized to factory dimensions with
typical target shooting loads with 7/8 to 1&1/8 ounce payloads. Make sure your gun is in
good working order and is completely unloaded. Check both the guns chamber and
magazine to make sure there are no live shells in the gun, and make sure the guns safety
is engaged and the barrel is pointed in a safe direction at all times.

Installation
Installation
Review Figure 1 to become familiar with the different parts of the MultiCatchTM. Place
the gun on a clean flat surface that won’t scratch the gun with the right (ejection port)
side of the gun facing up and the barrel pointed to the right in a safe direction. Position a
cloth or towel under the gun to ensure that the receiver is level with the table top and not
tipped. Doing so will aid in properly positioning the MultiCatchTM on your gun. Close
the bolt and remove the factory supplied bolt operating handle from the bolt according to
the gun manufacturers instructions.
Wipe the indicated areas of the receiver with a soft cloth and common rubbing alcohol to
clean the surface for attachment of the MultiCatchTM mounting bases and let dry. Install
the Parking Handle in the bolt in place of the factory supplied operating handle. The
shock absorber portion of the Parking Handle should point to the right (barrel end) after
installation. Ensure the Parking Handle is completely seated in the bolt. See Figure 2.
Next remove the Brass Hinge Pin from the Front Base of the MultiCatchTM so the lower
half of the Front Base separates. An adhesive strip is attached to the underside of the
lower half. See Fig 3.
The lower half of the Front Base is attached to the gun immediately in front of the
ejection port as shown in Fig 4. It is important that this piece be properly positioned with
the left edge of the lower half flush with the forward edge of the ejection port and
properly aligned with it. On Teknys model guns there is a styling recess in this area and
you may want to trim an extra piece of the supplied adhesive strip to fill in this recess to
make it level with the rest of the receiver.
1
With the bolt in the closed position hold the lower half of the Front Base with the right
hand so that the contoured surface with the adhesive strip is facing down with the hinge
side facing to the right (barrel end). The upper surface of the lower half of the Front Base
has two indexing marks which are the same width apart as the sides of the Parking
Handle. See Fig. 4 With the adhesive strip protective film still in place hold the lower
half of the Front Base in front of the Parking Handle so that the indexing marks line up
with the sides of the Parking Handle and the left edge is flush with the front edge of the
ejection port as shown in Fig 5. While maintaining this alignment place a piece of
masking tape on the receiver so that the upper edge of the tape aligns with the lower edge
of the properly positioned lower half of the Front Base. See Fig. 6 Next lock the bolt in
the open position and remove the protective film from the adhesive strip. Without
touching the receiver, re-position the lower edge of the lower half so that it is aligned
with the upper edge of the masking tape and the left edge of the lower half is flush with
the front edge of the ejection port. Press down firmly so that the base attaches to the gun
as shown in Fig. 4. Then remove the masking tape.
Next remove the Parking Handle from the bolt and set it aside. Re-assemble the hinge
consisting of the lower and upper halves of the Front Base and re-insert the Brass Hinge
Pin. See Fig. 7.
Next insert the lower half of the Rear Base into its recess in the upper half leaving the
protective film on the adhesive strip in place. See Fig 8.
While gently pressing on the lower half of the Rear Base to hold it in its recess, lower the
combined halves of the Rear Base on to the receiver. The MultiCatchTM is shipped with
the Jaws in the closed/released position. However to ensure that the Jaws are in the
closed/released position, slide the Jaw Trigger rearward with your finger. If the Jaws are
in the open/cocked position, this will cause them to snap into the closed/released position.
See Fig.9. The closed/released Jaw’s will hold the Jaw Trigger out of the way so that it
does not interfere with re-installing the Parking Handle. Re-insert the Parking Handle
into the open bolt. See Fig 10. Always ensure the Jaw’s are in the closed/released
position before inserting the Parking Handle into the bolt to ensure it is fully seated and
will not dislodge. Align the MultiCatchTM so that the Parking Handle is centered
between the Rails with the bolt locked in the open position. Use a piece of masking tape
placed on the receiver to mark the lower edge of the Rear Base when the Parking Handle
is properly centered between the Rails. See Fig 11.
Next remove the Parking Handle from the bolt and remove the protective film from the
adhesive strip on the lower half of the Rear Base and re-install in its pocket in the upper
half. Lower the assembled Rear Base onto the receiver so that its lower edge is aligned
with the upper edge of the masking tape and press firmly so that the adhesive strip
attaches to the receiver and then remove the masking tape and re-install the Parking
Handle into the open bolt. Next, take a single live shell and using the crimped end
depress the Jaw Cams all the way down until the Jaw Trigger springs forward to engage
the rear ends of both Jaws and holds them in the open/cocked position. See Fig. 13. The
bolt can then be released and proper clearance with the Rails on each side of the Parking
2
Handle in the forward position can then be verified. Never close the bolt with the
Parking Handle installed unless the Jaws are fully cocked. Doing so will cause excessive
wear on the Parking Handle and impair the operation of your MultiCatchTM over time.
When properly installed the upper Rail of the MultiCatchTM should be parallel to the top
of the guns receiver and there should be approximately a 1/32” gap between each Rail
and the side of the Parking Handle when the bolt is in both the open and closed positions.
See Figs. 11 & 12. A 1/32” drill bit can be used to verify correct spacing if desired. The
gap doesn’t have to be perfect but it should be close.
It may take a couple of try’s to get the proper alignment and extra adhesive strips are
included for that purpose. The strips can be trimmed with scissors to fit the mounting
bases. Please note that the protective film on each side of the adhesive strip has a
different color. The red print side should be attached to the mounting bases and the black
print side should be attached to the gun. This will help ensure that the strip will release
completely from the gun and adhere to the mounting base after removal.
Operation
At an appropriate shooting location ensure that the gun is unloaded and the safety is on
and that you and others in your immediate vicinity are wearing eye and ear protection
appropriate for shooting. Hold the gun in your left hand with the installed MultiCatchTM
facing up and the barrel pointed in a safe direction. Make sure the Jaws are cocked in the
open position and if not take a single live shell and using the crimped end depress the Jaw
Cams all the way down until the Jaw Trigger springs forward to engage the rear ends of
both Jaws and holds them open. See Fig 13. Following the gun manufacturers
instructions, open the bolt all the way so that it locks in the open position.
Single Shot Operation
Always verify that the Jaws are fully opened/cocked before firing the gun. Firing
the gun with the Jaws closed/un-cocked can severely damage your MultiCatchTM .
For firing a single shot, take the same live shell and align the rim of the shell base with
the Rail Slots (see Fig. 9) and drop the shell into the receiver just as you would normally
load the gun for a single shot. See Fig 14. Chamber the shell by closing the bolt.
Shoulder the gun, point it in a safe firing direction, disengage the safety and when ready,
fire the gun in a safe direction. When loaded with a single shell the bolt should
automatically lock in the open position after firing and the ejected shell will be caught by
the Jaws and Rails as shown in Fig 15.
Remove the ejected shell from the MultiCatchTM by sliding it forward along the Rails.
The rim of the shell will engage the Jaw Cams and by continuing to firmly push the shell
along the Rails the Jaws will open. Guide the shell into the front of the MultiCatchTM.
As this occurs the Jaw Trigger will again slide forward and engage the rear ends of the
3
Jaws and hold them open for reloading. Continue sliding the shell forward until it is
removed through the front of the MultiCatchTM. See Fig 16.
Repeat the loading and firing sequence with a single live shell as described above until
you are comfortable with single shot operation. This will also help to “break in” your
new MultiCatchTM.
Two Shot Operation
Re-engage the safety and make sure both Jaws are being held in the open/cocked position
by the Jaw Trigger. If they are not, cock the Jaws with the crimped end of a live shell
and load it into the guns chamber as described above. Firing the gun with the Jaw’s in
the closed/un-cocked position can severely damage your MultiCatchTM . Next load a
second live round into the guns magazine as you normally would. Shoulder the gun and
point it in a safe shooting direction. When ready, disengage the safety and fire the gun in
a safe direction with a single pull of the trigger. After firing, the first shell will be caught
by the Jaws and Rails. However because the gun was loaded with two shells, the bolt
will not lock in the open position after firing the first shot. After ejecting the first shell
the bolt will travel forward in order to chamber the second shell and in doing so the
Parking Handle will push the first ejected shell along the Rails and engage the Jaw Cams
thereby automatically re-cocking the Jaws and “parking” the first ejected shell in the shell
parking area of the MultiCatchTM Front Base. The gun is then immediately ready to fire
the second shell. See Fig 17.
Next, fire the second shell in a safe direction. After firing, the bolt should lock in the
open position with the first ejected shell retained in the Parking Area and the second
ejected shell caught and held by the Jaws and Rails. See Fig 18. Slide the first ejected
shell forward out of the parking area and remove it from the MultiCatchTM . Then slide
the second ejected shell along the Rails as before to re-cock the Jaws. Continue sliding
the second ejected shell through the parking area to remove it from the MultiCatchTM.
Both ejected shells can now be properly disposed of or retained for reloading.
Repeat the loading and firing sequence with two live shells as described above until you
are comfortable with two shot operation. This will further assist in the “break in” of your
new MultiCatchTM. This model of the MultiCatchTM unit is only designed to catch two
shells. Never load your gun with more than two shells with the MultiCatchTM installed
on it.
Clearing a Jam
All autoloaders jam at least once in a while. When one occurs, make sure the gun is
pointed in a safe direction at all times and place the safety in the on position. If you
experience a classic “stove pipe” jam with the shell partially ejected through the
MultiCatchTM Rails (see Fig 19) the jam can usually be cleared by firmly grasping the
ejected portion of the spent shell and pulling rearward (to pull the bolt back slightly) and
outward until the shell rim engages the Rails. The shell can then be slid along the Rails
4
and removed through the front of the MultiCatchTM unit as you would normally. Make
sure the Jaws are properly re-cocked after doing this and if they are not, re-cock them
manually using the crimp end of a live shell as described above in the “Operation
Section”. Also ensure that the Parking Handle is fully seated in the bolt as a “stove pipe”
jam can sometimes dislodge the Parking Handle from its fully seated position in the bolt.
If you experience an internal jam where a fired shell is not partially ejected, make sure
the gun is pointed in a safe direction at all times and place the Trigger safety in the on
position. Remove the Parking Handle and either remove the MultiCatchTM unit from the
gun by pulling the Brass Hinge Pin from the Front Base and lifting the main
MultiCatchTM unit off of its mounting bases as described below in the “Removal
Section”. This is the recommended method for accessing an internal jam. However after
removing the Parking Handle, the Rear Mounting Base Tab can be gently flexed rearward
to release the Rear Base of the MultiCatchTM. The MultiCatchTM unit can then be pivoted
forward using the Front Base hinge. See Fig 20. However if you use this method be
very careful not to over flex the Rear Mounting Base Tab as it can break which is not
covered by the warranty. Which ever method you use, once the ejection port area is
exposed the jam can be cleared. The MultiCatchTM unit is re-attached to the gun by
reversing whichever method you used to remove it.
After clearing a jam always ensure the MultiCatchTM Jaw’s are re-cocked before loading
and/or firing the next round. Severe damage to the MultiCatchTM can result if you fire
the gun with the Jaws in the closed/un-cocked position.
Unloading Unfired Shells
Make sure the guns safety is engaged and the barrel is pointed in a safe direction.
Unfired shells can be unloaded by removing the main MultiCatchTM unit from the gun as
described above or with it attached by making sure the Jaws are in the open/cocked
position. Hold the gun with the ejection port side of the gun facing downward and
following the gun manufacturers instructions for removing live shells, manually cycle the
bolt back and forth by hand using the Parking Handle as shown in Fig 21. As each live
round is ejected it will be caught by the Rails and Jaws just as a fired shell would be and
it can then be manually guided along the Rails by hand and through the front of the
MultiCatchTM.
Removal of the MultiCatchTM
Make sure the gun is completely unloaded. Check both the chamber and magazine and
make sure the barrel is pointed in a safe direction.
With the Jaws in the open/cocked position open the bolt all the way so that it locks in the
open position according to the gun manufacturer’s instructions. Lay the gun on a nonscratching flat surface, ejection port side up. Remove the Parking Handle by firmly
grasping it and pull it straight out from the bolt and set it aside.

Next remove the Brass Hinge Pin from the Front Base by grasping the bent end and
pulling it out of the hinge and set it aside. Next grasp the upper half of the Front Base of
the MultiCatchTM and lift the entire unit away from the gun. See Fig 22. It should come
clear of both mounting bases and set it aside. Your guns original operating handle can be
re-installed and you can use your gun as you normally would leaving the MultiCatchTM
mounting bases attached to the gun so that the MultiCatchTM can be easily re-attached
later.
If you prefer, each mounting base can easily be removed by firmly twisting it until the
adhesive material “shears” allowing removal from the gun. For re-installation,
replacement adhesive strips can be attached to the mounting bases and trimmed to fit.
Maintenance and Storage
Always make sure the gun is completely unloaded before performing any maintenance on
or storing your gun. Check both the chamber and magazine. A small drop of oil should
be periodically placed on each Jaw Spring, the Trigger Spring and the Jaw Hinges and a
dab of light grease can also be applied to the rear edges of the Jaw Cams as shown in Fig
23. The Rails should also receive a light coating of oil periodically to avoid rust. The
main MultiCatchTM unit should be periodically removed from the gun and gently cleaned
with a soft brush to remove any accumulated dirt or powder residue. A cloth with a small
amount of an appropriate solvent can be used to loosen stubborn material.
If you store your gun with the MultiCatchTM attached you should do so with the bolt
locked in the open position and with the MultiCatchTM Jaws released from the Jaw
Trigger. The Jaws can be released from the Jaw Trigger by pushing rearward on the
Parking Handle to push the Jaw Trigger all the way back to release the Jaws from the
cocked position.
PLEASE NOTE THE FOLLOWING
The MultiCatchTM uses 3M brand CommandTM Strip Mounting and Replacement Strips to
attach to the gun. A package of these is supplied with each MultiCatchTM . Additional
strips can be obtained at most hardware stores. The strips supplied will resist some
moisture but are not recommended for use in very rainy weather. 3M makes a more
water resistant version of its CommandTM Strip brand which is also available at most
hardware stores.
Although the strips are very durable, try to avoid long term exposure to direct
summertime sunlight as the adhesive can soften at high temperatures. If you must leave
your gun sitting in a gun rack exposed to the summer sun for a long time, try to position it
so that the side of the gun with the MultiCatchTM attached is not exposed to the direct rays
of the summer sun.
Please note that the CommandTM Strips used are about .040 inches thick and raise the
MultiCatchTM off the side of the gun by that amount. This allows the pivoting Jaws to
6
clear the guns receiver without contacting it. If you intend to use some other method
(adhesive or mechanical attachment) to attach the MultiCatchTM to your gun be sure that
whatever method you use also provides sufficient clearance for the Jaws to pivot.
Some guns eject spent shells farther than others. On guns which have very vigorous shell
ejection an occasional shell may “pop through” the Rails. If this occurs the “pop
through” shell should be on the ground near your feet.
Never replace the Jaw Trigger Spring supplied (See Fig 8) with another spring. The size
and tension of the supplied spring is necessary for proper operation of the MultiCatchTM .
Using a different spring could prevent proper operation and result in severe damage to the
MultiCatchTM and will void the warranty.
The MultiCatchTM has a thirty (30) day from date of shipment full money back guarantee
(returned in good condition in original packaging) and a one year repair or replacement
warranty (shipping excluded in each case).
We hope you enjoy your MultiCatchTM and that it makes your recreational shooting
experience more pleasant and convenient!
