GHK High Output G.2 Co2 Powered Magazine for GHK M4 GBB Airsoft Rifles

"I’ve ordered a total of 4 of these GHK CO2 M4 mags..
10/13/17 x1, 3/2/20 x2, 3/13/20 x1. Strangely, the first mag ordered back in ‘17 had the best feed lips. These last 3, I had to widen the mouth (Dremel, 30sec) of the feed-lips on the hop-chamber side, so they would feed better/easier. Fantastic build quality otherwise.

"Excellent magazine. I wish they made a hpa version of this mag. It works great in my emg f-1 receiver.

"Worked well for me out of the box. They're tough to fill for the first few times, be patient and go slow. Once the springs wore in a little, they fill a lot easier.

"Bought 5 of these. You Must oil them before you use them for the first time!
1 has a valve leak straight from factory (very disappointed about that)
You may want to consider buying a Rare earth magnet to get the CO2 canisters out as they tend to stick.

Overall amazing mags and will be buying more

"This magazine works on the G&P WOC Challenge kit.

"Great mag. Thank you Evike.com for carrying this item!

Pro:
Works better than the OEM WA made gas mag, better air seal
Works in COLD WEATHER and doesn't get effected by cold weather.
You put in co2 cartridges rather than charging it with gas....which could be a pro since 12g co2 are easier to carry onto the field.


Con:

"this does not work with the g&p woc challenge kit, at least not without heavy modifications. the mag was too big to properly fit in the mag well, after I shaved down the sides though it worked great. still waiting on someone to make a co2 mag that works with g&p.
