I bought a complete upper for a .300 blackout build. The upper was priced well, arrived quickly and was of great quality. I opted for the mil-spec charging handle and it was a little sticky so the builder called me after I sent an email. We talked through it and I ended up just upgrading the charging handle anyway. He was willing to replace anything and was just a really nice guy. I would definitely buy from MAS Defense again.

.300 BLK UPPER

Product was shipped and delivered promptly. No blemishes and operates well. Looking forward to putting more rounds through it. The only thing I didn't care for was the dust port sticking. Hence 4 stars I'm sure it will wear in.
