The SilencerCo Velos LBP 7.62mm suppressor (SilencerCo part no. SU5419) uses low back-pressure technology to cut the blowback that reaches the shooter while keeping strong sound suppression. SilencerCo builds it around a 3D printed Inconel 625 core fully welded to 17-4 stainless steel front and rear modules. It is rated for calibers up to .30 caliber and has no barrel length restrictions, so it suits rifles from short barrels to long. SilencerCo calls it the most durable suppressor it has made, and it is full-auto rated. It is a hard-use rifle can for shooters who want less gas in the face.
