Magpul PTS MOE pistol grip for M4/M16
 

I'm looking to buy one,
http://velocityarms.ca/index.php?mai...roducts_id=238, seems like a good deal, has anyone had problems using these? On a past thread,

it seems like the guy had a hell of a big problem, but the motor plate didn't have a nub on it, unlike the one from VA, can someone please confirm that version works on a standard CA/TM motor and won't cause any alingment issues? Thanks!
