Scratched buffer face
Parts fit correctly. Buffer face had scratches / disfigurement which indicate prior use. Might have been a returned part that made its way back into stock.

Terrific buy
Purchased a few months ago and extremely satisfied. The buffer i received was silver not black and the tube retainer had a qd sling hole in it so it didn’t match the picture exactly but im very happy it had a qd mount. And the buffer tube was extremely smooth on the inside wich made it much quieter than the other “budget” ? buffer tube i purchased elsewhere. Also customer service could not be better. This is my go-to place from now on.
