I am thinking about buying a MGI upper and lower receiver and was wanting to know if anybody has had any experience with them. Pros, cons. Any help would be appreciated. Thanks, JB

I have one and think it's great!

It's very easy to change barrels.  It takes less than a minute.  Magwell changing takes longer but is still easy.  

Very little (if any) POI shift when changing barrels.

The only negative on mine was the fire control group holes.  I installed a Geiselle trigger and couldn't adjust the stages properly because the holes were oversize.  I could push the oversize Geiselle pins in easily with my fingers.  I installed a Timney instead and it's been working fine.
