    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.

    Not to bad

    I was looking to build a rifle on the low and found this set up and it’s all great parts I’m not worried about anything with this system it’s all standard stuff for the money I was happy it’s all finish in a nice black finish looks like it will wipe down clean but yeah i got everything beside a grip and trigger for my build and saved a lot of money
