If I did that, I'd wanna go all the way with a A1 lower, Nodak has a nice one. But I'd also be temped to do an original 601/602 SP1 style upper with no FA and a no fence lower. For now I got a few modern lowers that need a home. Maybe I'll do a full on A2 for now and then go with a1 clone later. Still need to get a CAR stock for my 733, its sporting a magpul right now. Basically, what I'm saying is, I like shooting with peep sights. Feels like more of a refinement of the art than putting the dot on things and going bang. Although I still got a few with optics and dots lying around too.
