Nice upper Sunday, December 7, 2025 : Kaarlo Elonen from Waynesboro, VA United States   Used this upper on a 9mm AR pistol build. I like the slick side and forward assist is unnecessary on 9mm. Price was attractive too and lowest I found for slick sided upper. Upper went together with no problems and dark finish matched the lower. Happy customer. Was this review helpful to you?

Photos do not show the MAS engraving on top... Wednesday, April 30, 2025 : from FL United States   I do not like the engraving and would have liked to know it was there and to have the option to order with no engraving. Fit and Finish otherwise is 5/5 Was this review helpful to you?

Absolute Show Stealer Thursday, February 20, 2025 : Nich Miller from El Dorado, AR United States   We needed an upper for a last minute SHOT Show display and I found MAS Defense. I can't believe I'd never heard of you before because this thing is crisp!! We bought a couple more, before the show, because we wanted them for our displays AND because MAS ships fast as heck! The uppers were held by hundreds of people and caught a lot of admiration. Since we were selling a barrel/muzzle device, our choice of upper was something we got to brag about. You're making something that is consistently in-spec, gorgeous, tough as nails, and incredibly well priced and I (we) appreciate it. Was this review helpful to you?
