"this is a very good product you can leave the battery plugged in and it wont ruin the fcu. It it is very small and can fit through your buffer tube so when you go to maintenance your polarstar you dont need to unconnect it from the fcu wire. Te only down side is you have to use trigger pulls to program it so if you want your gun to shoot 50 rps you would have to pull the trigger 50 time. Over all this is a good product if you have limited space.
