Absolute tank of a handguard. I bought it to mount to an airsoft gun (VFC AK-74M GBBR) and had to file the trunnion contact surface to get it to fit, but I don't blame the handguard. It looks amazing and functions perfectly, a must have for anyone looking to modernize an AK!

This handguard is one of the best things that on installed on my milled Arsenal AK. It went together really nicely. Had to make less than a 1mm of adjustment to the section that slides underneath the rear sight assembly with a little fine grit sandpaper. Added some love taps from my hammer, and it was tight solid connection. It really makes this AK look awesome and more versatile with the M'lok's. LOVE IT!
