Guntec Micro Flash Can Slim Profile Features The Guntec USA Micro Flash Can is machined from solid T6 aluminum and finished in matte black for durability and a clean low-profile look. Threaded for 1/2x28 muzzles it is sized specifically for 5.56 and .223 Rem chamberings the most common AR-15 pistol calibers. Its primary function is pushing flash forward away from the shooter s eyes which matters most on AR-15 pistols where shorter barrels tend to produce a more visible muzzle flash. That flash control helps preserve sight picture and night vision during low-light shooting. At 1.245 inches in diameter and 2.5 inches long this micro can is specifically sized to fit into most slimline thin free floating handguards where a standard-diameter device would not clear. That slim fit makes it a natural match for compact AR15 pistol builds designed around minimal bulk and weight. Builders chasing a clean low-profile muzzle end on a pistol caliber or 5.56 AR15 pistol will find this can threads on without clearance issues. It is a simple effective upgrade for anyone finishing out a slim-handguard AR15 pistol build.
