Building or repairing an AR-15 carbine means starting with a solid foundation—and that begins with a reliable buffer tube assembly. The KAK Industry AR-15 carbine buffer tube kit gives you everything needed to complete the rear end of your receiver in one box. Whether you're assembling a new rifle, upgrading an existing build, or replacing worn components, this mil-spec kit includes the tube, buffer, spring, castle nut, and end plate, so you're not hunting down parts separately.
Built from 7075 aluminum with a hard-coat anodized finish, this buffer tube is engineered to handle the wear and pressure cycling of semi-auto fire while resisting corrosion. The 3-ounce carbine buffer pairs with a chrome silicon spring to manage recoil consistently, and the six-position design lets you dial in the length of pull for your body and your mission. Whether you're running a lightweight upper or a heavy barrel setup, adjustability matters when you're fine-tuning the feel of your rifle.
KAK's mil-spec design means it plays nice with standard AR-15 components—your existing buttstock and buffer will mate up without modification. The hard-anodized finish isn't just cosmetic; it's protection against the wear that comes from regular use and cleaning. If you're the type to tinker and improve your rifle piece by piece, or you need a straightforward, complete buffer tube assembly for a new build, this kit cuts out the guesswork.
