A couple of months ago I purchased a colt le6920 and it is a great shooting carbine. I have installed a quadrail on it and a weapon light at the 6 oclock position. Yesterday I installed an aimpoint pro on this gun and I am amazed at how well I can hit with it. This is my favorite new toy and was thinking this gun is now the best shtf/hd rifle I could have put together. Anyone have any ideas on what else I could add to this setup to make it better besides ammo and practice?
