The Geissele Automatics MRGG 25-Round Magazine is engineered to meet the demanding requirements of the US SOCOM Mid-Range Gas Gun program. Built entirely from premium stainless steel, this robust magazine offers vastly superior cold-weather performance and structural durability compared to traditional polymer options. It features a single laser seam weld on the front and back to provide an incredibly tough construction that eliminates the weak points of conventional spot-welded designs. The specialized feed lip geometry is mathematically optimized to present cartridges at the perfect angle, drastically improving consistency and eliminating feeding failures. Designed to drop into any standard AR-10 platform, it provides absolute reliability across multiple heavy calibers, including 6.5 Creedmoor, .308 Winchester (7.62x51mm NATO), and 6.8x51mm.
