The Area 419 Hellfire Self-Timing Muzzle Brake for .223/6mm, 1/2-28 thread, black nitride finish (brand part no. 419HF-BN-6MM-1228) is built for any bullet caliber up to and including .243 (6mm), covering .223, 5.56 NATO, .204, and .17 caliber rounds. Area 419’s self-timing design uses a universal adapter that stays permanently on the barrel, so the brake and collar assembly always lands correctly oriented without guesswork, and a simple knurled nut times it with no tools required. Rearward-facing ports deliver serious recoil reduction — independently tested at 52% on a 6.5 Creedmoor rifle, about 4% better than some of the most popular brakes on the market — while a proprietary port design controls muzzle rise without top porting. The 1/2-28 thread fits the common .223/5.56 barrel shank size directly.
