all that needs is a magazine extension about level with the bottom of the grip and, Im not sure about the end if thats a supressor or what, but that would have to be added and then that nerf would be just about right, short of lacking a better paint job.
I know it looks closer, and i know thats a nerf gun. its interesting because the guy sold it on ebay and it went up to like $200. for just a nerf gun with barely and mods thats pretty amazing.
Get a famas or a type 97 replica. Thats what it more resembles. Only problem is that they are both bullpups so you have to do a magazine mod. As for the extension just pick up another famas and work your magix
Well I bought one on the way home from work and its allready in piees on my floor. I brought part of it to work to use my bosses dremmel tool to dig out the air restrictor. Well see how it goes.
