KRISS Defiance DS150 stock (FDE) (DS150 FDE)
A drop-in replacement buttstock for AR-15/M16 carbines. It uses mil-spec sized receiver extension tubes. The frame profile avoids snagging and shields the release latch, preventing accidental activation. It includes a standard 0.30" thick rubber butt-pad to prevent slippage even with body armor or modular gear. Flat Dark Earth version.
