It appears that this round can drastically improve the performance of any AR-15 weapon chambered to .223/5.56 mm. Superior accuracy, wounding capacity, stopping power and range have made this the preferred round of many special forces operators, and highly desirable as a replacement for the older, Belgian-designed 5.56×45mm SS109/M855 NATO round.
The ArmaLite AR100 is a 5.56×45mm NATO caliber short-stroke piston gas-operated, 5.56×45mm NATO assault rifle fed from 30- round and 100-round drum magazines that eject from the magazine insert when empty and are discarded during a firefight.
The cartridge that would become the 300 BLK already had a slow speed with its designated heavy bullets. SOCOM added a noise suppressor, and by lowering the bullet speeds further to below 1,000 feet per second (sub-sonic), a significant lowering of the noise level was achieved, while still meeting the minimum performance requirements.
The 5.56 mm round had to penetrate a standard U.S. helmet at 500 yards (460 meters) and retain a velocity over the speed of sound while matching or exceeding the wounding ability of the .30 carbine cartridge. [50] This request ultimately resulted in the development of a scaled-down version of the Armalite AR-10, named the ArmaLite AR-15. [51]
They also have a new modified gas system designed to reduce barrel vibration [14] and can shoot two-inch groups at 100 yards, which is 2 minute of angle (MOA) accuracy. [ 16 ] Around 2007 or 2008, Ruger added a heavier, larger-diameter barrel visibly tapered from gas block to muzzle.

A flip-up rear sight with two settings for firing at distances of 200 and 400 m (early models had a rotating drum rear sight that provided 100, 200, 300 and 400 m sighting range apertures). The Model LV ( Visor ) is a marksman variant equipped with a fixed STANAG mount over the rear sight base; the optic generally used in this role is a ...
A Brenneke-style shotgun slug. A shotgun slug is a heavy projectile (a slug) made of lead, copper, or other material and fired from a shotgun.Slugs are designed for hunting large game, and other uses, particularly in areas near human population where their short range and slow speed helps increase safety margin.
