The NEMO Arms 300 Win Magazine is a 14-round, polymer-constructed magazine built specifically for the NEMO Omen and other platforms chambered in .300 Winchester Magnum. If you're running a magnum rifle that demands reliable feeding and real-world durability, this is the magazine engineered to keep up with your hunting or range work. NEMO designed this from the ground up around belted magnum cartridges, so it handles the unique geometry and pressures of big-bore rounds that standard magazines weren't built for.
What makes this magazine stand out is the attention to detail in the engineering. The enhanced polymer follower is anti-tilt, which means consistent, smooth feeding shot after shot—no binding, no wobble. The stainless steel spring resists corrosion and maintains tension over years of use, whether you're running it in the field or at the bench. At just 7 ounces unloaded, it won't weigh down your rifle, and the black finish blends cleanly with modern tactical or hunting setups.
Maintenance is straightforward: the magazine disassembles easily for cleaning, so you can keep it running smoothly without hassle. It's chambered in .300 Win Mag, but also accommodates 7mm Remington Magnum and .338 Winchester Magnum, and will take cartridges up to 3.50" overall length—meaning if you reload or run premium long-range ammunition, you've got headroom.
