The Wasatch/Weesatch will hold 2 FAL/M1A mags in the pouches easily. Not having any G36 mags, I cannot speak specifically about this, but my guess is this shouldn't be a problem.
I currently have in stock the Wasatch and Weesatch in Multicam (plenty of each) and in OD and Khaki (running low on both), along with the shoulder pads for them.
I have no Woosatchs in stock.
