Always Great Service November 6, 2020 : Calvin MT from Pierz, MN United States   At a time when it’s tough to get anything 2A related, the service and speed in which it was to my door was again great. Nothing but impressed with the quality of the products. You’d be hard pressed to find better quality in the same parts from some of your higher end companies you’d pay 3x the amount for.

Great price great quality October 29, 2020 : Casey from Grass Valley, CA United States   It’s my first purchase from mas defense and honestly it was a shot in the dark. I was skeptical because of the price specifically. But turns out they make quality products. It’s not a billet upper but really let’s be honest, it’s still going to outlast me. I’m shooting .300 subsonic rounds and it hits. I love it. Tight grouping at 400yds so far haven’t taken it any further this is my home defense build Was this review helpful to you?
