The PTR VENT 1 7.62x51mm suppressor is a full-size .30 caliber rifle can built around a monolithic 3D-printed titanium body and PTR’s Purposely Induced Porosity (PIP) technology (brand part no. V1-3080101). PIP uses controlled porous structures and gas pathways to manage expanding gases, which PTR says reduces the pressure buildup of more restrictive designs, a real benefit on a semiautomatic host. At 12.3 ounces without the mount, it adds little weight for a full-size rifle suppressor. PTR approves it for 7.62x51mm NATO, .308 Winchester and .300 Blackout, and in PEW Science testing on a 20-inch Savage .308 with Federal XM80 it earned a Suppression Rating of 57.3.

Key Specifications

• PTR lists the calibers as 7.62x51mm NATO, .308 Winchester and .300 Blackout, covering bolt guns, hunting rifles and AR-10s.
• Length is 8.74 inches, full-size length for real sound reduction on a .30 caliber rifle.
• Weight is 12.3 ounces without the mount, light for a full-size .30 caliber can.
• Diameter is 1.75 inches, as PTR lists it.
• Construction is a monolithic 3D-printed titanium body, with no separate baffle stack to loosen.
• The finish is a black PVD coating, a hard exterior layer that resists wear.
• The mount is a 1-3/8×24 HUB interface, which opens up a range of compatible mounting systems.
• A 5/8×24 direct-thread adapter is included, so it threads onto a standard .30 caliber muzzle out of the box.
• For 7.62x51mm PTR recommends a 14-inch barrel, with 12.5 inches acceptable at some cost to suppressor lifespan.
• PTR rates it full-auto capable, a measure of how much heat and pressure the titanium core handles.
