Je Machine Tech Carbine Buffer Features The Je Machine Tech Carbine Buffer is machined from aluminum and finished with a black oxide coating that resists corrosion and wear inside the buffer tube during repeated cycling. Sized specifically for AR-10 platform rifles running a carbine length buffer tube it measures 2.50 inches and weighs 3.80 ounces a weight chosen to work with carbine length gas systems and spring combinations. Controlling buffer weight is one of the simplest ways to tune an AR-10 s cycling characteristics and reduce bolt carrier bounce. A properly matched buffer also helps keep felt recoil consistent across different ammunition loads. Because the buffer slides directly into the existing carbine length buffer tube installation requires no additional gunsmithing beyond a standard takedown of the rifle s lower receiver. The aluminum construction keeps the part lightweight compared to steel alternatives while still holding up to the repeated impacts of normal cycling. Je Machine Tech builds its AR platform components to fit standard mil-spec dimensions so this buffer drops into most AR-10 carbine length builds without modification. For an AR-10 owner chasing smoother cycling and more consistent recoil this buffer is a straightforward upgrade available for sale at GrabAGun.
