⚙️ Product Details

Built for Dirty Work.

The Milsig M17 G3 is the next evolution in magfed realism and durability. Featuring the proven HeatCore blow-forward system, this third-generation marker delivers exceptional consistency, true mechanical full-auto, and a rugged, field-ready build engineered for serious operators.

Since the original M17 CQC launched in 2014, MILSIG has continuously refined the platform. The G3 continues that legacy—equipped with enhanced internals, a refined spring and bolt for improved air efficiency, and a new headless magazine system that reliably feeds both .68 caliber roundballs and shaped projectiles.
