    Nice adjustable gas block that works as advertised. Had a small issue with the first one but they sent me another without question. Grendel hunter is a good company and I will purchase again from them.

    Great adjustable gas block, don’t let the price fool you that your getting a cheap P.O.S. It installs great, every thing about it works as it should. This is my second block that I’m running, I have them on both my AR’s. Just don’t forget to loosen the set screw before trying to adjust your gas, it strips out faster than you think. But that was my fault, not the quality of the block. I will be making more purchases in the future.
