B.O.S.S. Guillotine 556


Available on backorder

SKU: GU-15060-556-SS-12 Category:



The Guillotine is an ultra high-performance, compact silencer that is among the lightest and most durable 5.56mm silencers on the market.  At 1.5″ x 6″ and right at 12 oz without a mount, you’ll hardly notice this can hanging off your barrel.

The Guillotine features our proprietary, Nikola Tesla-inspired, Coaxially-vented baffles that route the gasses through the silencer for a longer duration than in a standard baffle configuration, dramatically reducing the overall volume of the weapon when compared to other silencers of similar size.

The Guillotine includes a direct thread mount in 1/2 – 28, but accepts any standard HUB 1.375-24 pattern mount, including SilencerCo ASR Bravo, or DeadAir Keymo, as examples.
