The Zion-15 Rifle includes a 15 inch free-float handguard with M-LOK compatibility and B5 Systems stock and grip. This rifle uses a chrome-moly vanadium heavy barrel and a mid-length gas system. Zion-15 upper and lower receivers are hammer forged from Mil-Spec 7075-T6 aluminum with a type III hard anodized coating. A flat top rail provides plenty of space for mounting optics.
