INTRODUCTION
The purpose of TRS-MP5 conversion kit is to quickly and easily convert a regular rifle into an effective training weapon which does not
use ammunition. Using compressed gas instead of ammo gives the opportunity to fire a large number of simulated rounds at a negligible
cost. The only original parts removed from the rifle are bolt carrier, ejector and magazine. This system cycles the weapon’s firing mechanism as it would in actual fire while simulating recoil, providing an audible blast and marking the point of impact with a laser. Cycling
motion, recoil and blast are arranged purely by pneumatic mans and batteries are only needed to energize laser pointer. Trigger feel is
not altered from the original in any way so shooter can practice with the real trigger. Each “firing” cycle is initiated by the strike of the
unmodified hammer.
TRS system supports weapons with all trigger modes: semi-auto, burst, and auto. Cyclic rate of the system is approximately 14 rounds
per second or 840 rounds per minute. All components of the kit are made of hardened steel with corrosion resistant finish. After a training session, the entire assembly can be quickly removed from the rifle, without special tools, making the weapon available again for use
with live ammunition.

PARTS DESCRIPTION
Actuator: Replaces original bolt carrier and produces simulated recoil every time the gun is “fired”
2. Connector Plate: Provides compressed gas passage from magazine to the actuator
3. Magazine: Replaces the original magazine, stores compressed CO2 gas
4. Laser Pointer: Projects a spot on the target as a short pulse of light, mounts in the muzzle of the barrel

INSTALLATION STEP BY STEP
Make sure that the gun is unloaded and chamber is empty.
2. Remove original magazine, and bolt carrier from the rifle, following
standard field-strip procedure. (Fig.2)
Fig. 2: Take-down of the actual rifle.
3. Remove ejector tab with its spring and store it in a safe place for later
re-installation. (Fig.3)
4. Lubricate contact surface inside upper receiver, rails of the recoil actuator and the recoil spring.
Fig. 3: Ejector removal.
5. Please examine the Actuator Piston (Fig.4). The end that goes into a
barrel is an adjustable mandrel. Turning of the collet allows fine tuning of the mandrel for a precise fit into the barrel of the MP5. Turn the
collet (Fig.5) and test fit the Actuator Piston into the barrel until a fine
“slip-fit” is achieved. If the mandrel is too tight it will cause issues in
removal of the Actuator Piston.

6. Install actuator assembly into the upper receiver (Fig.4). If installing in a compact rifle (MP5-K) you must use the short (60mm)
pneumatic actuator and must remove the 37mm long plastic bushing from the recoil spring guide rod. The screws at the end of the
guide rod are loctited. You will require pliers or a vise to hold the guide rod and a good screw driver to break the screws free. After
removal of the 37mm bushing, re-Loctite® the screw(s) and tighten. (Fig.5)
NOTE: The MP5 may utilize both the long (78mm) and short (60mm) actuator; the MP5K will ONLY work with the short (60mm)
actuator.
7. Install connector plate in magazine well (Fig.6). Secure plate with screw using a flat blade screwdriver (Fig.7). Before installing the
screw, make sure it has three good rubber o-rings on it.
8. Close upper receiver.

9. Insert CO2 magazine in place (Fig.9). Make sure it slides over the mating pin easily and locks in place. After you assured that magazine fits correctly, fill it with CO2 gas (Fig. 8)

Fig. 8: Installation of Connection Plates.
10. Pull charging handle all the way back slowly in order to verify that recoil cylinder slides freely back and forth without binding. Release charging handle forward.
11. Batteries are pre-installed at the factory. To charge, unscrew laser from laser holder (knurled portion) by turning counter-clockwise.
It uses three coin cells No. 392. With positive + pole towards the barrel. Keep barrel pointed down when replacing laser module.
Battery life exceeds 200,000 shots or two years.
12. Apply oil film on laser mount rod and insert laser pointer inside the muzzle end of the barrel. Turn clockwise, mandrel will expand
and lock in place (Fig.11).
WARNING: Laser light, avoid direct eye exposure.

13. Insert pressurized magazine in place. System is ready for operation, aim at the target and pull the trigger.
14. Sight in laser point, if needed, using 4 screws (Fig.10) to adjust “windage” and “elevation”. Use .050” Hex key. Do not over-tighten
screw. Doing so could crush laser module.

Fig. 12: Laser module can be removed (screwed out) by turning
CCW. It uses three coin cells No. 392 with positive + pole towards
the barrel. Keep barrel pointed down when replacing the laser
module. Battery life exceeds 200,000 shots or two years.

BATTERIES
Three silver oxide coin cells No. 392 are used to power the laser. Battery life typically exceeds 100,000 shots.
VII.
LASER FUNCTIONALITY
Laser module transmits a brief pulse of light at each shot. Infrared laser light is invisible to the naked eye but can be detected by using
night vision equipment. For invisible laser, the blast of the gun cycle serves as an audible indicator of laser radiation.
CAUTION - Do not stare into laser beam. Do not point it into anybody’s eyes or into reflective objects. Accidental dropping
of weapon may cause laser activation.
VIII.
MAINTENANCE
A.Lubrication
Following areas must be lubricated on regular basis using Teflon based grease:
•
Upper receiver rails where the actuator rides in with gun oil or grease.
•
Gasket at outlet of the magazine.
B.
1.
Remove all pressure from the magazine.
2.
Put 3 to 5 drops of air tool oil or grease into
the magazine opening.
3.
Re-insert the magazine into the gun.
Seal Replacement
Magazine seal can be replaced as necessary. Picture shows how to replace magazine seal using a special wrench:

LASER MODULE
A laser module is provided as a part of the air recoil system. This laser module transmits a brief pulse of light at each shot which marks
the point of impact on a target. Depending on a model, this light can be visible or invisible to naked eye. Blast of the recoil serves as an
audible indicator of laser emission. Laser module is mounted at the muzzle end of the conversion barrel. It is energized by three silver
oxide coin cells No. 392. Fresh batteries are typically installed at the factor before shipping to the customer.
NOTE: All TRS laser are Class 3R laser and emit laser radiations. Laser light, avoid direct eye exposure.
CAUTION – Use of controls or adjustments or performance
of procedures other than those specified herein may result in
hazardous radiation exposure.
