This is a muzzle brake, not a flash suppressor. The muzzle device is a BRO-HCC (Black Rain Ordnance, Hexagonal Competition Compensator). While Sir Joseph Whitworth first developed the principle of polygonal rifling in 1853, in recent years it was promoted principally by Heckler & Koch, mostly in handgun barrels but also in some of their high-end rifles, such as the PSG1 sniper weapon system. In theory at least, polygonal rifling supposedly provides a number of advantages, of which some are a better gas seal around the bullet, less projectile deformation, reduced buildup of bullet jacket material, reduced sensitivity to stress induced barrel failure and increased barrel life. Polygonal rifling features "rounded" lands and grooves instead of the sharply defined rifling usually found on rifle barrels. The barrel is fluted to reduce weight, increase strength, increase the surface area for improved heat dispersion and because it looks good. This twist rate is an excellent and popular compromise for accurately accommodating a substantial range of projectile weights. The 18-inch, button-rifled, polygonal barrel, with three lands and three grooves, has a 1:8 right-hand twist and was made from ordnance grade 416 stainless steel. now has sixteen production rifle models with variations bringing the total to 49 different versions. Shotgun News recently received a caliber 5.56x45mm NATO rifle for test and evaluation.
