Handguard and gas tube cover set for installation on Saiga/Vepr/ AK based rifles. Fits all Saiga, WASR, Arsenal, IO and other AK absed rifles with mil-spec receiver and front retainer. Due to different tolerances in AK based rifles some minor fitting maybe required. Consists of two parts Keymod handguard and gas tube cover with 1913 Picatinny rail. This system allows you to solve the problem of setting collimator sights and tactical accessories (lasers, lights, grips etc.). Simple installation requiring no gunsmith (installed instead of the regular handguard and joined together with four bolts). Does not abstract iron sights. Rugged construction from aircraft-grade aluminum ensures the longevity of the product and the absence of thermal deformation under the most demanding conditions. Integrated Picatinny rail for installation of top collimator sight. Availability of Key Mode allows you to install additional accessories.
