Certified Glock Nut
based on the magazines and the suppressors I'm gonna guess 5.56 on the first and 9mm on the second.
Winner winner chicken dinner!
Thought it was obvious; I thought wrong. OP has been updated.
Shooter who's 9mm mags do you use for the AR?
Colt. But Spikes or Metalform (who actually makes/made the mags for both companies) would serve you just as well.
IME, the CProducts mags are hit-or-miss, and the polymer ProMags are pretty much junk. Converted UZI mags are durable and feed fine, but won't activate the bolt catch on the last shot.
