JE Machine Tech PS-BFSC4 .223/5.56 AR-15 Stabilizer Buffer System V2 – 4140 Steel

The JE Machine Tech PS-BFSC4 Stabilizer Buffer System V2 is a self-contained replacement for the traditional AR-15 carbine buffer and recoil spring assembly. Designed specifically for rifles chambered in .223 Remington and 5.56 NATO, the system combines the buffer and spring into a single drop-in unit.

Constructed from high-strength 4140 steel, the PS-BFSC4 is designed to provide smoother cycling while reducing buffer noise and felt recoil. It is intended for use with standard carbine buffer tubes and installs in place of the conventional buffer and spring without permanent modification.
