Unrivaled Siege Brake SB3-5.56

• Slightly slimmer and lighter than our UB brake
• Uses an internal expansion chamber to reduce recoil and maximize tunability
• Tunable via opening up “tuning holes” with a drill at expansion chamber (instructions provided)
• Simplified design is perfect for all builds
• Drastically reduces recoil and also functions as a compensator
• For .223/5.56mm or 5.45mm caliber rifles with 1/2″-28 barrel threads
• Includes crush washer
• Makes 16″ overall length on 13.7″ or longer barrels (possibly 13.5″ but depends on barrel thread length)
• 3.100″ Overall length with the actual length after muzzle crown being ~2.600″ (legal for most competition divisions)
• .894″ Diameter at widest point
• 3.2oz Weight
• No frills design without threaded adjustment ports is less costly to manufacture so we pass the savings along to the end user
• Brakes are bead blasted then go through QPQ Black Nitride giving them a slightly matte black finish
• 100% made in the USA like all of our products

Our UB brake is still slightly more effective but the Siege brake is a great option for general use on non “gamer gun” builds or even for the serious competition shooter who prefers a lighter muzzle device and/or doesn’t want to mess with the adjustments of the UB brake.
