Global Ordnance Monolith 15A 5.56 NATO 16.1" 30rd Rifle

The Global Ordnance Monolith rethinks the AR rifle around a bufferless operating system, which is what lets the stock fold to the side. Its heart is a one piece barrel machined from a single bar of steel: bore, barrel extension, gas block and a Dead Air KeyMo muzzle brake in one part, so there is nothing to pin, weld or shift. That makes it a good suppressor host, since a KeyMo can locks straight onto the brake.

This 15A model is chambered in 5.56 NATO with a 16.1 inch barrel and a 1:7 twist, and it comes with one 30 round magazine. The handguard has M-LOK slots and interlocks with the upper for stability, and a Picatinny rail runs across the top. Controls are ambidextrous, including the bolt lock and release and the thumb safety, and the charging handle is a folding forward type. The side folding stock has an adjustable cheek rest. It uses more than a dozen fewer parts than a standard AR and weighs under 6 pounds.
