Whoah Lone Ranger! Just a heads up, ATI is not quality. Ive owned quite a few of their products and few were what I was expecting. I havent used their heatshield but most people say its flimsy, the sights are not adjustable and a quick bump knocks it out of alignment. This is on par with my experiences with their products. Personally I would have iron sights soldered to the barrel by a gunsmith or at least someone who knows what theyre doing. For a less expensive route you could go with a pedestal to raise the bead a little higher, though I dont know where you would find one. Some of the fiber optic beads look a little taller than the factory brass, and the XS big dot is definetely taller. Just some options to ponder
