5 of 5 Just freaking awesome March 12, 2025
Reviewer: Gustin Thunder from Phoenix, AZ  
I really wanted to try the 6mm ARC because of all the great things I’ve been seeing about it. Decided to pull the trigger, and so far I have 40 rounds through it. After about 25-30 rounds I started getting close to MOA while trying to zero it at 100 yards while it was really windy. I run it suppressed with a polonium and on setting 3 it ejects at a 3-4 o'clock with a PWS H2 buffer and Sprinco blue spring. Mike is the shit by the way, and would totally recommend buying from him. Thanks Mike!
