Good to have you over here D-CA.
Liking this set up, will run this scope for a bit to see how it holds up. Carbine runs like a top, no issues.

Came with a 30 round Pmag, I added all else, scope, mount, sights, covers and 20 rd Colt mag. The gun is solid, all of the normal expected features with staking, H2, etc. I didn't have the WOTG sling attached.
I would like to point out how sexy that 20 rounder looks.
