BOSS Guillotine 556

BOSS GUILLOTINE 5.56 SILENCER - LIGHTWEIGHT 5.56 SUPPRESSOR, COAXIALLY-VENTED TESLA-INSPIRED BAFFLE DESIGN

The BOSS Guillotine 5.56 is a compact, lightweight 5.56 rifle suppressor built from a 17-4 H900 stainless steel 3D-printed baffle stack inside a Grade 9 titanium tube, finished in Glacier Black High Temp Cerakote. At just 12 ounces and 6 inches overall, the Guillotine delivers elite suppression performance without adding bulk to your host rifle. Its proprietary coaxially-vented Tesla-inspired baffle design routes gases through the suppressor longer than conventional straight-through or K-baffle configurations, achieving superior muzzle report reduction in a 1.5-inch diameter package. The Guillotine is full-auto rated with no barrel length restrictions. It ships with a 1/2x28 direct thread mount pre-installed, but will also accept any standard HUB 1.375x24 mounting system. 

CAPITOL ARMORY'S OPINION

The 5.56 suppressor market is crowded at every price point, and most lightweight cans get there by cutting corners on materials or baffle complexity. The Guillotine takes a different approach. The 17-4 H900 stainless steel 3D-printed baffle stack and Grade 9 titanium tube are the same material pedigree you see on suppressors costing considerably more, and the coaxially-vented Tesla-inspired baffle geometry is a deviation from standard, outdated baffle design. It allows for longer gas dwell time inside the suppressor, which translates directly to better sound reduction, and BOSS is getting that out of a 6-inch, 12-ounce package. At that weight, the Guillotine is light enough that it will not meaningfully shift the balance of a purpose-built SBR or lightweight hunting rifle. If you are looking for a high-performance 5.56 suppressor that prioritizes weight savings and sound reduction without sacrificing durability, the Guillotine is built for that role.
