Im not a newbie to the AR but I have a stupid question...I have installed Extended Takedown Pins on my Colt to make it easier for me and my fingers to seperate the Upper\Lower...Here in lies the quandry....Is it possible to have put the Detent Pins in backwards ( is there a difference? ) only reason why I say this is the Takedown is harder to operate now than before.... all comments will be helpful......
