Sig Sauer Mag Mcx 7.62X39 28Rd Ss Blk
The Sig Sauer MCX 7.62x39 28-round magazine is a factory-spec, stainless steel double-stack magazine built to feed your Sig MCX LT rifle reliably. If you're running the MCX platform in 7.62x39, this is the genuine OEM mag you need—purpose-engineered for the gun it feeds, not an adaptation from another platform. At 28 rounds, you get serious capacity without sacrificing practical handling or reliability in a duty or range setup.
Built from stainless steel with an anti-friction finish and steel baseplate, this magazine is designed to withstand field use and frequent loading cycles. The double-stack geometry keeps round count high while maintaining a profile that feeds reliably through the MCX's mag well. Whether you're stocking spares for the range, building redundancy for hunting, or prepping for serious rifle work, OEM magazines eliminate guessing and compatibility headaches.
Sig Sauer factory magazines carry the reputation of the firearms they feed—if you trust the rifle, trust the magazine that came out of the same engineering team. This is the caliber-correct, platform-specific choice for MCX shooters who want to know their mags will work, every time.
