I have the AR Stoner 18" medium contour barrel (i.e. Satern Liberty) with 9/16-24 threading. Bought the Helio muzzle device to go with it and the muzzle device just isn't cutting it for me with muzzle flip - barrel moves too much to stay on target to observe impacts on longer range shots.
My main desire from a new device is to minimize muzzle movement.
It's a tough size and the only things I can find out there are 1) the AA Millennium which just seems too long at 4" for. an 18" barrel, and 2) Brownells has an OPs Inc. R3E2C muzzle brake for 30 cal. Reviewers with 30-06's say it greatly reduces muzzle flip and OPs Inc appears to be a major supplier of suppressors to elite US Forces.
Never heard of Ops Inc. before (and I don't necessarily trust the US Govt's purchasing decisions) wondering if anyone has experience with this device on a Grendel or if there are any other 9/16x24 devices out there other than the AA.......
