The TacFire A2 5.56 Complete Stock Kit Platforms AR-15 Polymer Black brings the classic A2 fixed stock profile back to your modern AR-15 build. Designed around a rifle-length receiver extension, this kit delivers a solid, no-rattle shoulder weld and durable polymer construction that stands up to hard range use. A hinged butt plate opens to reveal an internal storage compartment, giving you space for small tools or cleaning essentials.

This stock kit is built for standard Mil-Spec AR-15 lower receivers and includes the rifle length receiver extension tube, A2 buffer, buffer spring, spacer, and screw, so you have everything needed for installation in one box. Its 10.5-inch length and 5.56-focused design make it a natural fit for traditional rifle setups, training carbines, or retro-style builds where consistency and comfort matter. TacFire’s reputation for practical, reliable accessories shows through in this straightforward, purpose-built stock system.
