Yup, I figure having the upper will help at some point ...

But this is a pretty low priority firearm. I'm leaving the greastest single expense for last or until I just feel like funding it. Mags should be relatively nexpensive so I'll spend a little time finding those and the ammo could be used elsewhere. If I'm splitting the cost up I figure I might as well wait and see if I can save a few coins on the upper.

I could also take out the 9mm mag block a go another caliber upper. Maybe a .300BO upper in a year so...
