When I read an AAR of the classes that I have taken, will retake, or will be at soon that I have wanted to take and see just what has broken....well at first I thought meh, I'll just have with me bag of parts and tools, and a vice to attach to the hitch if need be. But now? I'm thinking screw all that and just having a spare rifle and if that one goes too, to also have this spare upper ready to go as well and diagnose/correct later on my own time on just what happened.

I see that Rooftop has the lower that I am interested in too. Ugh. I'd rather buy either a G47 or a G19 MOS instead. Maybe some other time.
