Adam Arms fix for AR over gas problem - montana - 06-09-2011
I've built two 6.5 grendels. The first was a 16 inch AA barrel and upper receiver. I had problems with the m-4 cuts not being true with the upper receiver. A little dremmel work solved that problem.Then I put a H3 buffer in it and it shoots great. Then I built a 18 inch grendel with the same AA barrel and upper receive. It had the same m-4 cut and receiver problem ,and fixed with the dremmel. Then I had over gas problems with the rifle that a H-3 buffer didn't fix. So I put a Adam Arms gas piston on and it and it runs perfectly. I have three other Adam arm's 5.56 rifles and they work great. I love the Adam Arms gas systems .

Two of my 3 Grendels, as well as a couple of 5.56 AR's have the Adams Arms system.
I like them. My DI Grendel has a AA Overwatch upper and it has been anything but trouble free,chambering and cycling problems. My Adams piston uppers, home bilt have been trouble free.
