Hi. I'm new here and I figure I drop in and say hello. I be getting my USP .40 within a day or 2. I'm also thinking getting a SL8-1. I do have a question about it though. I have done some research on the SL8-1. Found out that SL8-1 come with the flat long rail. The one I'm looking at getting has a short flat one and one with a BDC scope/carrying handle (I guess G36s). Is there any way to get the rails changed for a flip up iron sights and a small rail for a scope? where can I find accessories for this rifle?
