I dont know what to call this one. Its sort of an MP5 clone in 7.62x25. Barrel is from a ppsh41, bolt and carrier is ak74, flat is ak, gas tube and semi left hand safety parts are Galil, sights and fore end are HK, mag well and mags are PPS43. Its a blowback design using a cocking system like an HK MP5 on a form 1. Stock is from Ace. This is one FUN gun to shoot! It just dont know who its baby daddy is.
