PTR has just launched its new 3D-printed, purposely porous VENT Spiritus 5.56i suppressor.
PTR Industries has just expanded its VENT suppressor line with the Spiritus 5.56i. It has many of the same features that made the .30-caliber VENT 1 so great, but now in a more compact package that’s optimized for 5.56 NATO.
Made of 3D-printed Inconel and featuring PTR’s patented Purposely Induced Porosity, the Spiritus 5.56i is strong, heat resistant, lightweight (15.75 ounces without adaptor) and quiet for its small size (6.01 inches long, 1.625 inches in diameter). The Purposely Induced Porosity also helps to reduce back pressure since it allows gas to be vented through the porous Inconel (hence the VENT name).
The suppressor is also rated for limited full-auto firing (90-120 rounds fired in bursts, with a 10-minute cool-down to ambient temperature to maintain reliability). To help keep things cool, it’s finished with a heat-resistant black physical vapor deposition coating. For 5.56x45mm, the Spiritus 5.56i requires a minimum barrel length of 10.3 inches, but there’s no minimum for 5.7x28mm. For mounting, it’s HUB-compatible and ships with a 1/2×28 direct thread mount.
One quirk of the Spiritus’ unique 3D-printed, Purposely Induced Porosity design is that it will gradually become less effective as it gets dirty, but you can’t take it apart to clean like a traditional suppressor. That’s not a problem, however, as PTR has detailed instructions available on their website that explain how to clean the VENT either by soaking or rinsing it.
The PTR VENT Spiritus 5.56i is available now and has an MSRP of $1,249. Also, keep an eye out for the upcoming VENT 2 in 9mm and the VENT 3, a full-size 5.56 suppressor.
