Thinking of doing a run of 6" rail mounts for Sterlings. They would fasten without alteration to the cooling holes on the barrel shroud and allow installation of dot scopes. I should be able to mount them low enough that they would not obstruct the factory sights if an optic is not installed (can't promise that one just yet). If I can keep the cost down to $75.00 or so, is there any interest? How about shorter rails for lasers, vertical grips, etc?
