One Horse AR-15 Carbine Buffer Tube Kit Features The One Horse AR-15 Carbine Buffer Tube Kit centers on a 7075-T6 aluminum buffer tube that is CNC-machined for tight tolerances and hardcoat anodized for long-term strength. This 6-position tube is built to handle the repeated adjustment and recoil cycling of carbine-length stocks without loosening or wearing prematurely. The hardcoat anodized finish resists scratching and corrosion keeping the tube functional through heavy range use and rough handling. Because it is Mil-Spec dimensioned it works with standard carbine stocks and related components without fitment surprises. The kit rounds out the build with a carbine buffer a Mil-Spec recoil spring an end plate and a castle nut giving a builder everything needed in one package rather than sourcing parts separately. Having matched components reduces the chance of incompatibility between the buffer spring and tube during assembly. This all-in-one approach saves time on a build and ensures the recoil system functions as intended from the first shot. Manufactured in the U.S.A. the One Horse AR-15 Carbine Buffer Tube Kit is available for sale at GrabAGun for anyone finishing out an AR15 lower with a reliable adjustable stock setup.
