Q PorQ CHOP Suppressor, 338/8.6 Blackout, Stainless Steel Construction, Nitride Finish, Black, 1.75"X8.6", Includes XL Cherry Bomb Muzzle Brake with M18x1.5 Thread Pitch 

The first-ever Premium Steel Silencers developed in conjunction with 8.6 BLK. That's right, these silencers were made for the mighty big brother to .300 BLK. The deep draw process makes the steel cans more affordable, wildly durable, and lighter than any steel silencer on the market, it's lighter than any titanium silencers on the market! The Porq Chop and Short Chop are shipped with an XL Cherry Bomb in M18-1.5.
