Receiver to Frame fit.
 

How much side play of the reciver is deemed ok, and how would one tighten this play up? Thank you in advance.

Unless the gap is enormous, or looks dangerous...I wouldn't mess with it. SHOOT it for accuracy, and I am sure you will be surprised at the consistency of the grouping if you do your part.

Thank you John. I am currently on the hunt for a Sear/Trigger bar for it so I can shoot it with out the "double tap" that I experienced the first time out. Not to mention a couple of "slam fires". But it did group well when it didn't malfunction. Have 2 new mags on order as neither of my 2 feed consistantly.
