: Jk99 from Henrico, VA United States  
Awesome upper! Came in torqued properly! Fits on a majority of lowers fairly flush. Just an awesome buy for the price+ MAS defense sent me a patch i guess because i always come back! If you see this review^ spend some $ here instead of PSA.

5 of 5 Just as suspected February 8, 2021
: DAMIEN HARRISON from BAKERSFIELD, CA United States  
I received everything in my order it was flawless for the money spent it's the best on the market hands down I wish I could say I tell everybody about this company but the fact is that I do not I'm selfish and I like to keep them Secret so when I want something it's in stock I only tell good friends and real Americans and supporters of the Second Amendment and people who fix there AIR'S themselves if you decide not to buy it good for you I'll buy it
