5 of 5 Excellent Quality and Helpful Service February 6, 2023
: from Ocean, NJ  
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.

4 of 5 .300 BLK UPPER July 16, 2020
: Jon L from Bennington, NE United States  
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.
