Weapon Configuration Safety

With the many accessories available for the AR15/M16 weapon system on the market and the ease of which this weapon can be modified and accessories installed by individual shooters, a final weapon inspection is essential prior to firing. To help eliminate one potential hazard our 6.8 x 45-mm UCC barrels are threaded with the 9/16 x 24 thread pattern to prevent installation of smaller diameter 223 / 5.56 flash suppressors that utilize the ½ x 28 thread pattern.
