Prompt delivery and just what I needed
July 5, 2022
: T A from TX United States
If you're going to use this gas block to mount sights make sure the front sight compensates for the slight drop (I think 1/4") lower than the receiver rail. Just what I needed.

no waiting a week before you're items ship, the shipping rates aren't crazy, the products are great, glad I randomly found Mas Defense. I'll keep ordering whenever I need something.

September 18, 2016
: LANCE B
EXCELLENT all way around. Great quality product, excellent pricing, fast shipping, and most notably, excellent communication during and after the purchase process. MAS DEFENSE will be getting more of my business on future AR build needs for sure. Nice to see such service and prices.
