I have a 51T MAAD mount on my Saker and 4 51T muzzle devices. I have recently bought/built a few new rifles (including a 6.5 Grendel that I have had been waiting for the barrel since January). My problem is that nobody makes any 51t stuff anymore since AAC was dissolved in the bankruptcy. Has anybody heard anybody making 51T muzzle devices? I have found a few online but for the price people are charging, I could probably just switch over to the ASR. Does anybody here have the ASR mounts? How do you like them? I know that there are a couple of companies that make ASR compatible mounts which I am interested in because I don't like the three prong device and SiCo only makes the brake and the 3 prong hider.
