Spare 25 Round Magazine For Bulldog 3PX4 PX4 Airsoft Gas Blowback by Tokyo Marui / WE

"Great magazines for the price and are very nice. Pretty decent paint job and has pretty good build quality and performance. Almost as good as Marui but at a much better price point. Works great in my WE Bulldog Full Size.

PROS:
-Gas efficient(2.5 mags on a single gas fill on a 60 degree day, probably get 3 mags out on a hot day)
-Pretty good build quality. Not as good as Marui but it's pretty nice.
-Nice paint job. Somewhat glossy and dark and has yet to scratch after about 20 mag reloads
-Automatic gas pressure regulation. Will leak a little gas if overfilled so you don't blow any fill valves.
-Fill valve has a nice O-ring (My marui mags don't have one)
-Cheap price when compared to Marui mags
-Pretty resistant to cool down

CONS:
-Quality isn't as top notch as Marui but it's up there
-Had to lube up some of the internals because they were pretty dry

"PRO'S:
-Great quality!
-After fill, releases some propane - which at first may seem like a leaky mag- to avoid overfilling which is better for your mag long term.
-Really cheap when used with a coupon (I used the 20% off).
-Compatible for both the HK3 PX4 (WE PX4) and Tokyo Marui PX4.

CON'S:
-Plastic Magazine Lip so be careful not to release the spring fast or it may break.

DETAILED REVIEW:
Love this mag. A good replacement for the default mag that comes with the HK3 PX4 (WE PX4) that I got. The default one gets stuck and you have to shake the gun to get it out. This one comes out fluidly. Great mag for only being $24. If you use a coupon, makes the deal even better. I use this with my WE PX4 and it works great. I like how the mag automatically "leaks" out propane after a fill in order to prevent over filling which may damage your gun/mag long term. Definitely recommend to get for your WE/TM PX4.

"This is a great mag and it is IMPENETRABLE. I left it alone for an entire day and it still had as much gas in it as before.

Pros:
Good capacity (25 rounds)
No leaks
Gas-efficient

Con:
Sometime difficult to get BB follower aligned correctly with BBs


Also there is graphite or some other kind of dry lubricant that can get all over your fingers and under your nails when you pull down the BB followers. But at least it's extra lube.
