Samson B.R.E. Features The Samson Manufacturing B.R.E. is designed around a 6-position adjustable carbine receiver extension that integrates with mil-spec AR-15 adjustable stocks giving builders a familiar adjustment pattern on a buffer-less platform. The folding Picatinny stock adapter allows the attached stock to fold for a more compact overall package and the folding mechanism itself can be removed and reattached to configure the fold to the right side. This flexibility makes the B.R.E. useful across a range of builds where stowed length matters from truck guns to pistol-brace configurations converted for shouldered use. The ramp built into the extension drastically improves ease of installation reducing the fumbling that often comes with fitting an AR-15 stock to a receiver extension. Machined and finished in matte black anodizing the B.R.E. is constructed to hold up to repeated folding and adjustment cycles without loosening. It is intended for use on buffer-less setups such as the Brownells BRN-180 Sig Sauer MCX and Sig Sauer MPX broadening its appeal beyond standard direct-impingement AR-15 builds. The stock itself is not included so builders can pair the B.R.E. with whatever mil-spec adjustable stock best fits their intended use case. For AR-pattern builders assembling a buffer-less rifle or pistol who need a dependable folding stock interface the Samson B.R.E. is available for sale at GrabAGun. Samson B.R.E.
