but then i couldnt get the springs back.... the retaliator costs 45 freakin bucks in korea alone.... also it seems pretty stable. although the smart AR is getting a bit glitchy. sometimes it works some times not. but the increase in accuracy and sheer power is probably worth it.
You could just get the OMW retaliator replacement spring, and by the time you'd want your springs back id assume your gun would be toast, so you can just cut into the shell
