    Griffin makes great products. That was the reason behind my choice in this gas block. I’ve purchased other products made by Griffin that have held up. I will continue to be customer.

    Fixed My Problem

    Published by Brandon on 8th May 2020

    I am what many would consider a poor, so while building my AR10 I used a PSA upper. The adjustable gas block didn't work and I had constant cycling issues. Griffin Armament being less than 30 miles away from my house had the best quality part and it fixed my problem. Very pleased to say that I no longer have issues with my rifle.
