The Geissele Premium Mil-Spec Buffer Tube is the perfect choice for your AR-15 rifle or mid-length gas system. This reliable and durable buffer tube conforms to all mil-spec standards and features 6 stock positions. Made from 7075-T6 aluminum, it is machined with a type III hardcoat anodized finish in Geissele’s DDC for extreme durability. It also has a mil-spec diameter that ensures compatibility with most AR-15 stocks on the market.

This remarkable upgrade to your AR-15 will improve function and reliability, thanks to the three independent strands of wire that absorb energy and displace excess energy. With a 15% stronger average return force than a standard buffer spring, you’ll have no trouble stripping rounds out of the magazine – even when using dirty or steel-case ammo. Plus, the included mil-spec castle nut and end plate ensures a perfect fit on any compatible rifle. Don’t settle for anything less than the best – trust Geissele quality to get the job done right.
