I literally just threw this together an hour ago, so it's not even zeroed yet. Hopefully I'll get that done tomorrow assuming I'm not shoveling my driveway here in NoVA. So far I've spent about the past half hour doing the draw, presentation, and dry-fire thing, trying to get the hang of acquiring the dot. It's about as difficult as I expected, which is to say that the primary problem is finding the dot when your grip is off. Otherwise, this seems like it's going to have similar benefits to adding a RDS to a carbine. Hopefully I'll get some range time in the next two weeks or so and see if I can't wring this setup out. For now some pics:




Once I get good with it and I make sure nothing's going to break on me, I'll be using this as my carry setup.
