Magpul PMAG 10-Round 7.62 AC Polymer Magazine for Sig Cross .308 Winchester - Black

The Magpul PMAG 10-Round 7.62 AC polymer magazine for Sig Cross .308 Winchester rifles delivers serious capacity and reliability in a purpose-built platform. Built from the ground up for the Sig Cross short-action platform, this 10-round magazine lets you carry more ammunition for extended range sessions, hunting trips, or competitive shooting without sacrificing the sleek profile that makes the Cross such an effective rifle. Magpul's GEN M3 technology gives you the durability and performance serious shooters expect—this isn't generic surplus stock, it's engineered specifically for how the Cross feeds and chambers rounds.

The high-visibility follower includes a dedicated feed ramp for reliable empty-chamber loading through the ejection port, so you can reload on the fly without fumbling with the magazine well. Impact and crush-resistant polymer construction handles the rough treatment of field use, backcountry hunting, or heavy training schedules. The flared and detachable floor plate gives you positive control when seating the magazine and makes retrieval from gear or range bags genuinely easy. A paint-pen dot matrix lets you color-code your magazines for quick visual ID—handy when you're running multiple loads or working with a shooting partner. Made in the U.S.A., this magazine brings Magpul's proven reliability to your Sig Cross setup.

While engineered for the Sig Cross, the PMAG 10-Round 7.62 AC may function with other short-action AICS-spec bottom metal platforms, though it's optimized for Sig Cross rifles. Whether you're zeroing at 100 yards, pushing distance on steel, or hunting open country, having that extra capacity in a reliable, domestic-made magazine makes a real difference in how your rifle performs.
