We're looking into running A-1's, but have to get the correct size sight towers first. We're in the process of getting those lined out now. We could do the A-1 contour using the .75" base, but I don't think that they look right, so I won't run them.
They're in the works, just a bit further out on the horizon. We'll run standard lightweight's first, then if we think that the demand is there we'll look into running chrome lined ones. Unfortunately the mfg. side takes so long to get things running, even minor changes take 6-8 weeks if we're lucky.
