Black Ace Mossberg 500/590 RAIL #BAT-MS500R
So far as we can tell, this is the first manufactured Mossberg 500/590/590A1 quad rail produced [and what a great piece]! This Mossberg rail is the last word in quality accessorizing.
Prepare to be blown away, because this is the real deal. This Mossberg 500/590/590A1-compatible rail is beautiful and entirely functional. This work of art now allows any picatinny rail accessory, such as those on your rifle, to be mounted on the Mossberg 500/590 -even the 590A1. Take your shotgun to the next level!
