5 of 5 Nice so far December 15, 2020
: Big Stevie from Charlotte, NC United States  
I really hate to review AR products without actually firing them and putting them through the paces, but this is a gift for someone.  Upper came securely packaged.  Very nicely finished.  Upper and hand guard look very nice.  If it runs as good as it looks, it’s a winner, but time will tell.  So far so good.

5 of 5 Great deal! July 1, 2020
: LH from Goodyear, AZ United States  
Fit and finish were flawless. Cant wait to shoot it. The barrel alone is $240 so for $100 more you get receiver, handguard, tube and block. Assembled and test fired. What a deal. Hope they start making .224, I'll buy one for sure.

5 of 5 Superb Accuracy July 1, 2020
: Richard  
I've waited till I got out to the range to really test what the upper can do. Shooting 77gr TMK from Atomic Ammunition proved to be sub-moa despite being a mediocre shooter. When shooting out to 700 yards, when combined with a 4-14 RGRID-B reticle, this upper was ringing steel at reduced silhouettes all day.

Next, I wanted to see what Wolf Steel cased 55gr 223 ammo could do just for kicks. I have plenty and ammo is hard to come by nowadays. Imagine my shock when it was sub-moa at 50 yards and 1 MOA at 100! Using data on a ballistic calculator, I discovered that I can use essentially similar holds. I was hitting steel out to 670 yards! It's a testament to MAS Defense for assembling quality parts into a nice package that doesn't break the bank for the average citizen. I'll definitely look to buy more from MAS Defense and you should too.
