SSS.6.135 - PTR VENT 3 and the MK18 5.56x45mm Short Barrel Automatic AR15 Rifle (Free Version)
The VENT 3 is designed and manufactured by PTR Industries. It is a 223 caliber centerfire rifle silencer, intended to suppress the 5.56x45mm cartridge on barrels 10.3 inches and longer, with semiautomatic or fully automatic fire. The VENT 3 has a 1.6-inch diameter and is 7.7 inches long. The silencer may be attached to a variety of weapon systems depending on the user’s choice of mount; the included 1/2-28tpi direct thread mount increases the system length to 8.1 inches. Other mounting options are possible due to the rear of the silencer body being HUB compatible (1.375”-24 tpi threading). The entirety of the VENT 3 structure is monolithic and constructed from 3D Printed Titanium. The silencer weighs 11.7 ounces and the included direct thread mount weighs 2.2 ounces, for a total system weight of 14 ounces, as tested. The VENT 3 can be obtained from PTR Dealers.
