I only had one rifle with a threaded barrel for a long time. It came with a muzzle brake on it. One range trip and I took it off. Tired a flash hider next. Have settled with a linear compensator from Kaw Valley. No real data on accuracy differences but shoot ability with compensator seems the best for me and with better shoot ability better accuracy more likely. Second rifle with threaded barrel just has the end cap on it. Haven’t fired it yet.
