As far as midcaps are concerned for the g36
G&P>MAG>STAR>A&K
I have 1 G&P midcap, 4 Mag ones, 1 star, and 2 A&K. (I initially bought 1 G&P, 1 Mag and 1 star mag to test them- the A&Ks came with my used CA g36.)
The G&P mags are the best, but MAG midcaps very close quality wise (both brands feed flawlessly), the star midcap I have doesn't feed well in my CA (yes I initially lubricated it), and the A&K ones don't seat properly in my E1 or CA G36s (you can pull them out of the magwell without using the mag release) - although they do feed well.
Anyone know anything about the new ARES g36 midcaps? I just spotted them on Evike the other day.
