Unrivaled AR-15 5.56 NATO Siege Muzzle Brake

Based on customer feedback we made a lighter and simpler muzzle device with our 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

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.


Note: This item is only compatible with barrels in 5.56 NATO/.223 with 1/2"-28 barrel threads
