The Global Ordnance Monolith is the evolution of a bufferless rifle platform, featuring an innovative one-piece barrel, machined from a single piece of 41v50 ordnance grade steel using a proprietary process, to provide superior accuracy, reliability, and suppressor concentricity. This "monolith barrel" combines the bore, barrel extension, gas block, and Dead Air KeyMo muzzle brake into a single, seamless part that, when paired with a new heavy duty bolt design, represent a significant leap forward in a 70 year old design. The Monolith includes an integrated 1913 rail, ambidextrous controls, and folding forward charging handle. This revolutionary rifle platform is compact, lightweight, feature-rich, and will redefine your expectations of what a firearm can be. - Simplified Design: Monolith uses over a dozen fewer parts than a traditional AR.- Bufferless System: The Monolith's operating system eliminates any need for a buffer assembly, streamlining its structure for increased efficiency and reduced weight.- Integrated Components: The single-piece Monolith barrel is a precise and flawlessly engineered combination of Dead Air's Keymo Brake muzzle device, gas block, and barrel extension; no need to pin and weld!- Refined Gas Flow: A 45-degree gas port ensures perfect gas flow and decreasing traditional gas port size, optimizing the Monolith's performance as a suppressor host.- Enhanced rifling: The Monolith boasts superior barrel rifling for unmatched accuracy.- Heavy Duty Bolt: Monoliths features a rugged, heavy-duty bolt for reliability and longevity.- Interlocking Upper Receiver / Handguard: An innovative interlock feature between the upper receiver and handguard promotes added stability while simultaneously contributing to the platform's accuracy.- Integrated 1913 Rail Stock Mount: Monolith's versatility is further enhanced by the inclusion of industry standard 1913 picatinny rail integrated into the lower receiver, ready to accept all popular folding stocks or braces.- Ambidextrous controls: The Monolith prioritizes manipulability with ambi controls, including a newly patented bolt release that can be dropped by pressing on the ejection port cover.
