Questions & Answers
I see the weight,,, However What is the length? Of this buffer?? Expert Answer

It has a slightly extended length of 4.11 inches. This buffer is intentionally designed longer than a standard carbine buffer to prevent the bolt from getting a "running start" on a blowback 9mm and breaking the bolt catch.

Nice weight by MSG RET, Verified Owner, July 25, 2026
Using this buffer for my 45cal pcc build. Good weight. Should function nicely. Just wish the weight was marked on the buffer. The only weight designation was in the item description.
