SilencerCo Velos LBP 556

LOW BACKPRESSURE, HIGH DURABILITY

The SilencerCo Velos LBP 556 reduces gas blowback to the shooter while maintaining 137.1 dB average sound suppression at the muzzle. This is SilencerCo's first suppressor built specifically to address the discomfort and performance issues caused by backpressure in semi-auto and full-auto 5.56 platforms.

The internal design uses a 3D-printed Inconel 625 core fully welded to 17-4 stainless steel front and rear modules. This construction method allows for internal geometry that redirects gases forward rather than back into the action. The result: cleaner bolt carriers, less carbon buildup on optics, and reduced gas to the shooter's face on ARs, SBRs, and belt-fed platforms.

The Hoplon blast baffle deflects debris and extends suppressor lifespan on short-barreled and high-round-count firearms. At 5.98" long and 15.2 oz, the Velos LBP 556 adds minimal length while handling everything from 7.5" pistol builds to belt-fed machine guns. Full-auto rated with no barrel length restrictions.

The Charlie mounting system provides compatibility with ASR mounts, direct thread options, and third-party QD systems including Dead Air Key-Mo and Q Plan-B adapters. V-Series Cerakote finish withstands sustained high-temperature use.
