I already have 15 Aluminum U.S.G.I MilSpec(CProduct & Bushmaster) , 2 Steel H&K, and 2 Magpuls totaling 19 mags. The Magpuls are very nice and i would like to get about 6 more with the view window not to mention the 20 rounders i need for my RRA 10.5" pistol and Bushmaster Varminter.
I still enjoyed burning threw 80-100 rounds flawlessly in my $500 Olympic Arms Plinker when i had an original C-mag. I think they are designed very well compared to the 90 round snail drum mag. Compact,light,and efficient compared to a single steel drum. I never had a malfunction and they are just as "Operation" worthy as a Magpul if you ask me. I never even used the powdered graphite lube. A MG grade heavy barreled AR with C-Mags would make a poor mans M249 SAW.
With the price of ammo these days and not wanting to burn up a barrel i really just want one because I can and to show off to shooting buddys. I told myself i was going to get another one and I am while we still can. I already have enough Hi-Cap Glock,Beretta, and AK mags to last a lifetime.
