I would like to thank MAS for a quality experience. The site gave active inventory and I had no issues in my transaction. The upper I ordered was well constructed and packaging was appropriate. Shipping and notification were super fast. Thanks again.

5 of 5 Great customer support May 3, 2021
: Erik  
I thought I had a feeding issue when I first got this upper, I contacted MAS support and turns out it was just crappy steel ammo causing the problem. It runs brass cased 223/556 flawlessly. Customer support was fast, polite, and knowledgeable to help me figure out what was going on. I will be a returning customer in the future.
