5 of 5 Flawless January 20, 2021
: Andrew from Richmond, VA  
Absolutely fantastic Upper. On initial breakdown, the hand guard itself is lightweight and very sturdy, the upper receiver well assembled and perfectly aligned gas block. This runs flawlessly with the mid length has and BA barrel. MAS has built an affordable  and well crafted upper that competes with some of my top end rifles. Cant wait to purchase my next from them! Keep up the great work guys!

Great fit and finish, accurate barrel. Would be a good price even pre-craziness. Just hoping to catch the 18” version in stock soon as well!

5 of 5 Barreled upper January 15, 2021
: from Rock Hill, SC United States  
Going to go shoot this weekend and if this upper shoots like the other barrel and assembled upper I have gotten from MAS I’ll be beyond satisfied. Everything on MAS’s part was great, fair pricing(especially in today’s times), excellent assembly, test firing, and GETTING IT TO THE POST OFFICE time frame. The post office on the other hand had it held up for almost 6 days(which still isn’t terrible but not great given the distance it had to go) when it literally had to come 45 minutes down the road to be delivered. I know that’s out of MAS’s hands at that point so they can’t be falted for that. Just if you have another option besides usps at the moment it might be worth looking into as long as it wouldn’t cost a arm and a leg.
