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?
