Some arguments I’ve read against this procedure:
- This wear is normal.
- This wear is cosmetic in nature, and is nothing to be concerned about.
- The buffer is such a cheap and expendable part that it can easily be replaced.
Some of my personal observations or arguments for this procedure:
- Is this wear normal? To some degree yes, in extreme cases I say no. Is it so common that it has become accepted? To this I say definitely yes.
- Cosmetic? I guess to some degree all buffers wear. I’ve had bolt carriers that were finished during the manufacturing process that didn’t wear into the buffer face period. I guess it all depends on how much effort the mfgr takes in the final carrier finishing process.
- The buffer may be an easily procured part, and of course very easy to replace......
But, when I consider the ease at which this unnecessary wear can simply be eliminated or greatly reduced, verses say spending for a replacement buffer, anywhere from $22.95 for an “H” buffer, on up to $37.95 for an “H3” buffer, or $29.95 for a new buffer such as the Spike’s ST-T2 buffer, it makes dollars & sense to me to spend a few extra moments in the shop following the above lapping procedure.
