Global Ordnance Monolith 15P 5.56 12.5 Barrel 30-Rounds SB Tactical Brace

Overview

Global Ordnance Monolith 15P Features The Global Ordnance Monolith 15P chambered in 5.56x45mm is built around a one-piece monolith barrel machined from 41v50 ordnance grade steel using a proprietary process that integrates the bore barrel extension gas block and Dead Air KeyMo 2-port muzzle brake into a single seamless component eliminating the alignment tolerances and failure points of multi-piece alternatives while delivering superior suppressor concentricity and consistent accuracy in a 12.6 pistol-length format. A carbine-length gas system with a 45-degree gas port optimizes gas flow for suppressor use and contributes to smooth reliable cycling across the full range of 5.56x45mm loads and a heavy-duty bolt with enhanced barrel rifling and 1:7 twist completes a precision-engineered operating package built for long-term reliability. The bufferless operating system eliminates over a dozen parts from the traditional AR-15 design reducing total weight to just 5 lbs 3 oz and producing a more compact mechanically efficient platform than any buffer-dependent AR-format pistol alternative. The interlocking upper receiver and M-LOK handguard design adds structural rigidity that non-interlocking alternatives cannot match contributing directly to accuracy and shot-to-shot consistency from a short-barreled pistol configuration where mechanical precision matters most. The SB Tactical Aluminium FS1913 folding pistol brace collapses the overall length to 20.5 for transport and vehicle carry and extends to 29.5 for a supported shooting position delivering packability that fixed-brace and traditional AR-format pistols cannot match. A B5 Systems P-Grip 23 and flat AR-15 trigger provide a comfortable grip angle and a clean consistent break over standard mil-spec alternatives and the M-LOK handguard supports lights lasers and accessories at any position without the weight penalty of a full Picatinny rail. For shooters who want a suppressor-ready fully ambidextrous bufferless 5.56x45mm pistol with an SB Tactical folding brace and integrated Dead Air KeyMo infrastructure from the factory the Global Ordnance Monolith 15P is for sale at GrabAGun and delivers that next-generation AR performance in the most compact format available.
