This might be a dumb question, but is there a difference between a regular picatinny rail and a mil-spec 1913 rail? The reason that I ask is that I just picked up a Bushy with the B.M.A.S. quad rail system and the Tango down vertical grip that I bought won't fit! It looks like the Bushy rail system is wider than the Tango Down grip by quite a bit. The Tango Down grip is supposed to fit mil-spec 1913 rails.
Has anyone ran into this problem?
My TD foregrip had to be BEAT on to my YHM rails... and I had to trim a little plastic first just to get it that far.
Then, once it took forever for me to get it installed.... I realized I hated the pig.
Why did I sell my Dieter.... why God, why?
