The Geissele Automatics AR-15 premium buffer tube in DDC (Flat Dark Earth) gives your rifle platform the solid foundation it deserves. Built from 7075-T6 aluminum and finished with Type 3 hardcoat anodize, this mil-spec buffer tube delivers the rigidity and durability you need for reliable cycling across any build—whether you're running a precision rifle, duty gun, or hunting platform. At just 3.7 ounces, it's light enough to matter but engineered tough enough to handle real use.
This carbine-length tube meets all mil-spec standards for diameter and function, so it plays well with the vast majority of mil-spec AR stocks on the market. Geissele machines these in the USA, and the fit and finish reflect that commitment to quality. Six stock positions give you room to dial in a cheek weld or LOP that works for your body and your mission, whether that's prone shooting, hunting from a stand, or tactical applications where adjustability matters.
The package includes a mil-spec castle nut and end plate, so you have everything needed to get the tube installed and locked down properly. No hunting for the small stuff—Geissele bundles what you actually need. If you're upgrading a lower receiver or building an AR from the ground up, this is a no-nonsense choice backed by Geissele's reputation for precision engineering.
