MM BK1S Jailbreak Handguard

The MM BK1S Jailbreak Handguard is built around the Jailbreak-style front device look, but with a detachable design — the front device piece pops on or off, so you can run the full Jailbreak profile or strip it back to a plain handguard depending on the day. When it's fitted, the front device also does double duty concealing an MM BCAR200 or BCAR300 mounted at the front of your build. It's sized for the BK1S's stock 24cm barrel, so it fits straight on without any barrel changes.

The kit includes the centering piece and barrel nut needed for a proper fit, and is available in yellow and silver. If you're already running an MM BCAR200 or BCAR300 up front and want a cleaner look without the barrel attachment on show, popping the front device back on is the quickest way to tidy that up.
