AR-15 Micro MCBS Muzzle Comp Blast Shield System (9mm)

Description

The AR-15 Micro MCBS Muzzle Comp Blast Shield System (9mm) is a two-piece muzzle device assembly engineered specifically for 9mm AR pistols to manage side blast and concussion in confined environments. Constructed entirely from steel and finished with a durable Nitride surface, this system combines a micro compensator with a blast shield to redirect propellant gases away from the shooter and bystanders. The assembly threads directly onto the barrel using a 1/2×36 threads thread pitch, ensuring a secure and precise fit for compatible 9mm upper receivers. The compensator component features a perforated upper section and a threaded base, designed to vent gas efficiently while maintaining structural integrity under repeated firing. The accompanying blast shield is a larger hollow cylinder with circular ports around its open end and diagonal exterior grooves, acting as a physical barrier to further contain and deflect the concussive force generated by the muzzle device. Together, these components form a solid pattern system that significantly reduces the noise and pressure experienced during operation, making it an ideal upgrade for compact builds where blast mitigation is a priority. Weighing a total of 8.0 oz for both the muzzle brake and blast shield, the system adds minimal mass to the front of the pistol while providing substantial functional benefits. The all-steel construction ensures longevity and resistance to heat and wear, while the Nitride finish offers corrosion resistance and a consistent matte black appearance. Manufactured in the United States of America, this kit is a direct replacement for standard muzzle brakes or flash hiders that do not include blast shielding capabilities. The overall outer diameter of the assembly is 1.44 inches, and the total length is 2.0 inches, fitting within the spatial constraints of most AR-9 pistol builds. This system is supplied as a complete assembly, ready for installation on any 9mm AR-15 platform utilizing the specified thread pitch.
