Based on customer feedback UNRIVALED made a lighter and simpler muzzle device with their proven design.
▪ Slightly slimmer and lighter than our UB brake
▪ Uses an internal expansion chamber to reduce recoil and maximize tunability
▪ Tunable via drilling dimples 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
▪ .894″ Diameter at widest point
▪ 3.2oz Weight
No frills design without threaded adjustment ports is less costly to manufacture so UNRIVALED passed 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 UNRIVALED products.
The 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.
# For .223/5.56 caliber guns with standard 1/2″-28 threads.
