This offset buffer retainer is made for lower receivers in which the buffer retainer pin hole was drilled out of spec resulting in too much or too little carrier tail/buffer face contact, which can lead to damage, chatter marks, and beat up buffer edges. This is the solution to fix that issue

Milspec steel 

Properly heat treated for strength 

Black Oxide coating for corrosion resistance

    Works great and solved my slightly out of spec lowers buffer contact issues, used with a buffer tube that has BCG support extensions and there is enough meat on the pin to dremel it and make it work, would recommend

    Does the job if your buffer detent pin hole was drilled slightly off spec. Good price too!

    Great Solution

    I have an old Bushmaster AR that had been retired. Recently, I changed out the upper and started shooting it again. I noticed that the buffer was getting beat up. I tried different BCG's from other rilfes, but the buffer was still not resting forward enough. I ordered this pin and installed it. Now, the buffer is sitting in the right position and is not getting hit by the pin.
