Our expert's opinion

" I particularly like this setup because of the character that the Hard Kick Angry Gun kit adds to the Tokyo Marui GBBR's operation. The Sport-4, B33, and PT-5 setup also completely transforms the AKM’s feel and look, while the combination of the holographic sight and magnifier offers true versatility when it comes to aiming. "
