The Magpul Industries PMAG M3 Window magazine offers a lightweight, reliable, and cost-effective solution for 7.62x51 NATO (.308 Winchester) rifles, specifically designed for SR25/M110 pattern firearms. Crafted from impact and crush-resistant polymer, this magazine features durable dual-side transparent windows that enable quick round counts through a high-visibility coil indicator on the spring and numerical markers on the body. This innovative MagLevel system allows shooters to estimate remaining ammunition rapidly without compromising the magazine’s durability or performance. The stainless-steel, corrosion-resistant spring combined with an anti-tilt, self-lubricating follower ensures smooth feeding and enhanced reliability during demanding operations.

Designed for easy disassembly, cleaning, and maintenance, this magazine is optimized for durability and long service life, matching the lifespan of the rifle barrel itself. Its slim profile ensures compatibility with tight double magazine pouches, making it ideal for tactical and operational use.
