I'm willing to trd for a lbx 4020 plate carrier (color:black,size: medium) Some problems I'm having with my v12: 90-110 psi the engine is giving me 280-285 or less - depending on the bucking , the engine is going to jam. + on the back of the shell the left side was bent outward but my friend bent it back -Inconsistent fps 20 to 40 fps jumps +terrible air efficiency. 20 mags per tank fill(depends on the tank ur using). Those are the problems i noticed I'll add the the krytac receiver and upper but I don't have the stock, also a tank and reg . Can only meet local (LA)
