I bought the Patriot Synthetic in 338 Win Mag with the 24" threaded barrel. I wanted a super light weight rifle for Elk and basically it is all of that. I looked for something that had threads for a muzzle brake and this does except they are 11/16-24 and the barrel is so thin that there is no real shoulder to a brake to seat against. After searching for a brake that would fit and not finding one anywhere, I called a local gunsmith that makes custom breaks and will be taking the rifle up to him in a couple days to see what he can do with it. I've shot the rifle off a bench and as expected, the recoil is pretty stiff using 230gr Hornady Precision Hunter ammo. I mounted a Leupold compact Freedom 2-7x scope and basically this setup is pretty much what I was looking to have and if I can get a brake on it I think it will fill the bill nicely. I asked Mossberg Tech support to point me towards a brake and they danced around the question and weren't any help. Just my 2 cents worth on my first Mossberg rifle.
