2 diff. Ar's range trip .....trouble?

[green grunt]

OK.

You're fine unless you have a brain lapse and stick one of those 20 rounders in the BB'd rifle.

I go to the range with my BB'd AR and a keltech with 30 rounders.

If you are still nervous, only take 10 round mags and leave the 20's at home.

Fine as long as you don't put the featureless lower with the featured upper - flash hider and vfg come to mind.

I have done this many times. I usually leave the 20 rounders at home.
