Colt IUR.......What are you using for a lower receiver?

If you've got a CC lower from your SA, is there a reason NOT to use it and the BCG if you're also running an IUR?

Only the inconvenience of pulling the parts out and putting them back in. Takes a few seconds and gets your hands dirty but that's about it. Also, maybe some people don't like the extra wear on their bcg.

Thanks- kinda what I thought.

There's gonna be a lot of intensive wear what with my range usage - NOT. ;)
 
Brand new, complete factory Bushmaster lower that I got from the dearly departed Kodiak Outpost. They were too cheap to pass up!
 
I have an Aero Precision lower but the rear take down pin won't close all the way on my IUR but closes fine on my Vltor Muir upper just fine Any thoughts?
 
try that again.
