Want a flash suppressor for my 308 hawkeye compact with the 16.5" barrel, but the OD at the muzzle is too small (0.55") for a 5/8 thread, any ideas?Flash hider. .308 winchester recoil is pretty manageable. Going to go on a 16" barrel so I would like to tame the muzzle blast. I think a brake would make it not fun to shoot
