The railed gas tube will fit all (stamped and milled receiver) AK rifles with a standard length gas tube. Length is adjustable for variation between rifle manufacturers. The 5" of Picatinny rail provides space to mount optics and accessories. Its low profile of the rail allows lower 1/3 co-witness with some optics. The Railed Gas Tube will work with factory hand guard, independent of the short and long bottom rails. It replaces factory gas tube easily with no gunsmithing required. It is machined from hardened aircraft aluminum with stainless steel components and finished in black MIL-SPEC hardcoat anodizing.
