With the landscape in Law Enforcement and Military changing rapidly across the globe, many went looking for a heavier round with more stopping power. Welcome to the 7.62 x 51 (.308)! Due to the large and violent nature of this round, it was necessary to develop a Steel magazine that could survive the abuse inherent to this round. CPD® did just that, developing a magazine that can withstand the test of time. With its Isonite and proprietary black Teflon coating, this is the magazine of choice for Military units across the world.
