Some arguments Ive 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. Ive had bolt carriers that were finished during the manufacturing process that didnt 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 Spikes ST-T2 buffer, it makes dollars & sense to me to spend a few extra moments in the shop following the above lapping procedure.
