The Davidson Defense AR-10 Mil-Spec Buffer Tube Kit gives you the core recoil management components your build needs. This kit includes a 7075-T6 aluminum buffer tube with dry film coating, a 3.7oz buffer, recoil spring, castle nut, and end plate. Everything here is mil-spec spec compliant and built to handle the recoil impulse of full-power rifle cartridges.
The 3.7oz buffer weight is optimized for carbine-length buffer tubes on AR-10 platforms. This weight balances recoil impulse and bolt carrier velocity to keep your rifle cycling reliably without excessive wear on components. The dry film coating on the tube reduces friction and eliminates the mess of traditional grease-based lubrication while maintaining smooth operation through hundreds of rounds.
Every component in this kit meets military specification standards. The castle nut and end plate use standard mil-spec dimensions, so they'll work with any mil-spec lower receiver. The buffer tube itself is dimensionally consistent with mil-spec AR-10 platforms, making installation straightforward on any compatible build.
7075-T6 aluminum is aerospace-grade material chosen for strength without excessive weight. The Type III hard coat anodize finish protects against corrosion and wear. Dry film lubrication means no sticky residue buildup, which keeps your buffer tube cleaner and reduces maintenance between shooting sessions.
Follow safe handling and manufacturer instructions. Ensure compliance with all applicable federal, state, and local laws. Lower receiver not included.
