This might sound like nit picking, but here goes anyway...
I want an STI Edge. Love the full dust cover. However, I also want a light rail. Is is possible to have a gunsmith "mill" in a light rail? (i was looking at the edge's dust cover and it seems to be radius'ed slightly, not sure if it can be done?)
Of course, the STI tactical 5.0 is vertually the same thing, but does not have that full dust cover...
