Custom designed Handguard with picatinny rails for G&G RK 47 the 1,4J version, I think this should fit other replicas of AK47 but can't guarantee it. This was designed in Solidworks all by myself, I personally love the angled grip but others didn't fit that well cause of the curve on the end of the rail so I made one that does, other grips fit fine with no modifications, Upper one has two configurations with and without a rail, also the lower can be mirrored in your slicer if you're left handed. Enjoy
