finally got my hands on one of these. looks like usual magpul quality.  my rifle is built with seekins precision billet receivers, and the d60 will not seat.  drum body hits bottom of magwell.  anybody else have this problem?

Do you mean the SP one which has the extreme curve in the magwell?  If so, that isn't close to in spec, so I can't say I'm shocked.  Don't get me wrong, I'm not saying that makes the SP bad, it simply doesn't follow the design specs for the AR15 magwell.
