I don't mind doing that but I don't have my optic yet.I am still working with the BUIS that came with the Colt.I can shoot with them but I am not impressed with them at all.The aperature is designed in such a way that you get a lot of glare around the hole.My rear sight is also quite loose in it's parts.I can wiggle it back and forth a good bit.I haven't seen it changing groups yet though.

My front sight also seems to be ground slightly out of square.The FSB is not installed canted,the post it'self is slightly off.I'm looking for a good replacement now.

I can tell you that the off hand standing groups I shot yesterday were better than with the stock trigger and the speed at which I could accuratly shoot was nearly halfed.I was actually trying more to see how fast the trigger would reset and was very supprised at the groups I shot.
