I know this has probably been asked before i tried a search but had no luck. the bullet button on an Ar-15 seems to be a pain in the ****. anyways can the bullet button be installed on the rifle so the button is on the left side of the rifle???? i think it would make hitting the button easier and you could stay on target. also i know the law says the "tool" used to hit the bullet button cannot be attached to the rifle... so is the magazines with the little bump on the bottom that can hit the bullet button legal??? thanks in advance!!!!
