Fixed Butt Stock
CARBON FIBER STOCK
Description:
The Lancer Carbon Fiber Stock (LCS)
is a lightweight fixed stock for 5.56mm
and 7.62mm AR style rifles that uses a
fixed rifle length buffer tube (not
included). Applying our expertise in
advanced materials and product design, we’ve combined high strength carbon-fiber and
impact resistant injection molded polymer components to create a robust, lightweight
buttstock. The carbon-fiber tube has a custom profile that provides strength and a
comfortable cheek weld. The butt plate and front collar are injection molded from a specially
formulated impact resistant polymer.
