"Great mags, they can shoots about 80 rounds and then run out of gas
by kevin l. on 04/19/2014
"These mags are great and are pretty gas efficient, but I live in San Diego. I've dropped one of these mags on the dirt ground from like 2 and a half feet up and it still works perfectly. On a regular day in SD, I can get like 1 and a half mags out of one gas fill. I use a dump pouch with these and they still work fine despite being knocked around.

"this mag is great. it runs off of kwa's ns2 gas system so there isnt alot of gas consumption. its full metal and weighs a good pound or two. unlike what evike says it only holds 40 rounds. if you try to put in more then the follower lock engages after every shot till you get to 40 rounds. believe me i have tried putting in more and it didnt work. just keep it at 40 rounds. all in all great mag, howerver it does cost alot for the one mag. someone needs to make a CO2 version of this.
