Update on my 12/20/2015 review March 28, 2016 : Eric S   Couldn't be happier. Range d with the .300 BLK and Ozark Ordnance 147gr FMJ. Zeroed at 50yds and moved to 100yds using a 4 MOA dot optical sight with no magnification. All shooting inside the 4inch circle with my old eyes and I'm impressed. Function with my Olympic lower, full length stock and rifle buffer was flawless. Now to find the magic load this rifle likes and mount a decent scope to see how accurate it can be, which I'm sure will be awesome. Thanks MAS !! Was this review helpful to you?

Awesome company !! December 20, 2015 : Eric S   I ordered 3 items, so this will serve as review for all three - .300 Blackout HBAR upper receiver, M16 BCG and 7.2" knurled hand guard. All arrived within expected time frame, packed well, and most impressive of all, clean and well oiled. I have purchased brand new in the box complete firearms that were nasty dirty. Not this shipment, the only thing was a little carbon in the barrel form test firing. MAS also installed the knurled hand guard at no charge. All fits and functions well with my Olympic lower, and though I have yet to fire, (waiting on ammo) I'm sure everything will be perfect. I could not ask for a better product for the price, customer service, or genuine care for what they sell. MAS Defense rocks !! Was this review helpful to you?

16" 300 BLACKOUT UPPER - MIL SPEC BARREL NUT September 20, 2014 : Jerome W   Order arrived way faster than I anticipated. Well constructed, flawless. I haven't had the opportunity to shoot it much yet, but I'm looking forward to enjoying this upper. Besides for fastdelivery of a great product, the price was lower than I could find elsewhere. Thanks for exceeding my expectations! Was this review helpful to you?

Great Upper May 27, 2014 : James V   I just received my barreled upper before Memorial d and built it out with parts I had on hand. It shot great, putting the first two rounds through the same hole at 25 yards with iron sights. WhenI build another one, I will definitely come to MAS Defense first! Great product at a great price!
