Reptilia RECC-E Stock for AR15/M16 Carbine Length | Lightweight, Modular Carbine Stock

A purpose-built carbine stock that balances precision and portability.
The Reptilia RECC-E Stock delivers a constant cheek weld and modular compatibility across AR-pattern rifles without adding weight. Developed with input from military end users, the RECC-E accepts a standard AR15 carbine buffer system or an A5/SR25 carbine buffer system by swapping the receiver extension and forward stock section. At just 12.0 ounces including the proprietary carbine-length receiver extension, it gives you a rigid, repeatable cheek weld and ambidextrous QD sling mounts while keeping overall rifle weight down for long days in the field or behind optics.

Includes the proprietary carbine-length receiver extension (buffer tube) and all mounting hardware for quick installation. Patents pending. Made in the USA.

Why We Love It
