Hawkbait introduced an FTN6 thread adapter for KAW Magnum linear compensators used on 45-70 rifles. Muzzle device choices for that caliber remain more limited than for standard thread sizes, so the adapter lets users keep their FTN silencer adapters. The matching KAW linear compensator fits inside the Hawkbait 45-70 silencer model but might not suit other FTN silencers and could cause gas to vent incorrectly.
