I ran accross these guys at the NRA show and they are doing some great stuff. This is a rail that they ae makeing for the 870 and the 1100 platforms. We picked them up and we have them on our site now. I am working on them to try to get the price down some but there is a ton of work in here so I'm not sure how much I will be able to do.
