Great Lakes Firearms Custom Billet Magazine Features The Great Lakes Firearms custom billet magazine is machined specifically for the GLFA .300 Win Mag rifle holding 5 rounds of magnum-length cartridges in a rigid aluminum body. Billet construction gives this magazine tighter tolerances than a stamped equivalent translating to more consistent feeding and less flex under spring pressure. The black finish matches factory furniture on the GLFA platform keeping the rifle s overall appearance uniform. Because it is purpose-built for this specific rifle shooters avoid the fitment issues that can come with universal or cross-compatible magazines. Aluminum construction keeps the magazine s added weight minimal while providing the durability needed to withstand repeated field use and reloading cycles. This magazine is intended strictly for use with the GLFA .300 Win Mag and is not designed to function in any other firearm ensuring a precise reliable fit when used as intended. Owners looking for a spare or replacement magazine can count on consistent function that matches factory performance. This purpose-built design makes it a dependable choice for GLFA .300 Win Mag owners shopping at GrabAGun.
