#7.62x51NATO

Mission First Tactical is in the business of making affordable AR-15 accessories and they’ve recently released a new set of magazines specifically designed for the 7.62×51 NATO cartridge. The new MFG Extreme Duty Magazines are now available for use with SAAMI-spec 7.62×51 and .308 Winchester ammunition. The new magazines will be made available in both black and flat dark earth and according to Mission First Tactical, these magazines were made in cooperation with Frank DeSomma from Patriot Ordnance Factory and as such, these magazines are dedicated to his memory.

A little over two years ago, we shared a graphic on the common misunderstandings of the common .308 Winchester vs. the 7.62×51 NATO cartridge. Astute readers pointed out that the chamber pressure readers were incorrect on the graphic (which we did not create – only shared), which is true – a common mistake between PSI (Pounds per Square Inch) and CUP (Copper Units of Pressure). The 50,000 PSI of 7.62×51 NATO actually runs closer to .308 Win in pressure that the graphic would lead one to believe.
