UI have one of the new milled Colt carriers. However, as I shoot it, it is digging into the metal of the buffer. I repleaced the buffer and it is still happening. This doesnt happen with any of the other rifles we have. Any ideas?

I was told that the new bolt carriers are so light that is why they dig into the buffer.The old milling still had enough mass to be operated more smoothly and not at a higher velocity. Find someone who can get you a M-16 bolt and machine it to old specs.
