Our UltraSlim Delta 6X UltraSlim muzzle brake has a sleek, modern look and is slimmer than most 5/8-24 brakes, packing a ton of recoil-reduction efficiency into a small space — and at an amazing price.

•  Works with 5.56mm, of course, up to any caliber with a 6.X in the name — 6.0mm, 6.5mm, 6.8mm (perfect for 6mm ARC and 6.5 Grendel and 22 ARC)
•  Makes a 14.5″ barrel — when pinned and welded per ATF specifications — a non-SBR (Short Barreled Rifle) of over 16″ in length
•  UltraSlim, low-profile diameter allows a .750″ gas block to slide over for installation and removal convenience
• Four ports, optimally angled for recoil reduction yet with minimized blowback
•  Black nitride finish for all-weather durability
•  Fits 5/8-24 muzzle threads
•  Length: 2.25″
•  Weight: 2.1 oz.

Includes our UltraShims muzzle-device-timing, super-thin washer kit — a $4.95 value!

WARNING: Designed for maximum efficiency with 6.X cartridges and smaller: DO NOT USE WITH 7mm OR .30 CAL. CARTRIDGES OR LARGER
