Hearing Protection Act in SASS Wire Posted January 27, 2017 · Edited January 27, 2017 by Key Hay My neighbor has that system, with the surpressor threaded on to the muzzle brake, that is threaded on to the barrel. Not sure that it reduces recoil anymore than just a surpressor threaded directly to the barrel in felt recoil. We share the same smith in Idaho, and he's truly a machinist. He properly installed it for him. Its a 338 lapua improved. Couple things I don't like about the surpressor are the shift in point of impact, and the length of it. If you buy a 30 inch Hart for the velocity, then have to spin another 8 inches on it, it's too darn long. You either have to load tune, and zero the gun with it off or on, because the poa is different even though it will shoot tight either way. Now some gun makers are building their rifles with a short threaded barrel, with a protective thread collar on it figuring the buyer will put a surpressor on it. This ruins the velocity of the cartridge cutting 6 inches off of it. I spose if I were shooting high volumes of rounds in one spot on a bench, I'd buy one. Lunger In space (or Eastern Washington) no one can hear you scream..... Whee you're at Lunger nobody needs a suppressor LOL.
