The Wilson Combat Quell Ultralight titanium 9mm suppressor is a 6.75-inch rifle can with a .358-inch maximum bore, machined from Grade 5 6Al-4V titanium and weighing 9 ounces (brand part no. SP-QUELL-H9BLK24). Typical calibers for this size are .338 Federal, 9mm and .358 Winchester, so it moves between a pistol-caliber carbine and a big-bore AR-10. Wilson Combat machines it on 5-axis CNC equipment with a fixed baffle stack, aiming for minimal point-of-impact shift and a very low risk of baffle strikes. The black nitride K-Mount interface threads onto a 5/8×24 barrel and installs with a socket. It fits shooters who want one light can across their 9mm and .35 caliber long guns.
