Once you have this on one, you will want it on all the others. For the price, major improvement. You need a bolt catch roll pin tool or you will scratch it up getting the roll pin in/out. It DOES come with a single roll pin, but not the spring or plunger so don't lose that when you remove your existing one or if new you will need these parts in your LPK.
