- THIS HELPS SO MUCH!!!!, April 28, 2009

I recently bought this box mag for my Classic Army P90 and my first thoughts were AMAZING!!!! I probably got ten compliments from friends and others about how awesome my gun looked. Before I got this mag my other mag (the one that came with the gun and which didn't feed at all into my gun) was terrible. I don't know if it was just me or what but it is now at the dump. If you have enough for it PLEASE don't second guess it. IT'S AMAZING!!!!!

PROS:
1)FEEDS GREAT
2)FULL METAL (AS FAR AS I CAN SEE)
3)1,500 ROUNDS (in other words don't worry about bringing other mags unless you're playing a HUGE game)
4)AMAZING LOOKING
5)It's cheaper than other P90 box mags
6)It's very easy to put bb's in the box

CONS
1)The BB's kind of rattle around in the mag
2)You need to buy an extra high cap M16 Style mag for it

- Bad for lefties, READ REWVIEW, September 07, 2009

If you're left handed it sucks 'cause it blocks your grip position. So i'm sorry to say that i'm left handed so make sure you can hold this before you buy. THANKS... i'm sure it's a cool thing to have, but you're better off with a hi-cap for lefties like us.

- Must Have For Any P90 User, July 22, 2009

I bought this lovely device for my Classic Army P90 and it is working great. Due to the design of the P90 high capacity magazine, it constantly jams during combat which has resulted in my "death" multiple times. The P90 mid caps are too expensive and hold too little rounds. Another problem with P90 magazines is that they require special gear to hold them. This box magazine gives the P90 amazing fire power of over 1000 rounds which will last you any game. I personally bought a Vietnam style M4 magazine so that the P90 retains its sleekness.

Pros:
1. Feeds flawlessly
2. Has a decent amount of metal parts
3. Holds either 1500 (regular style high cap) rounds or 1390 (Vietnam style I recommend this one)
4. Looks great and keeps the P90's streamline form
5. No need for special gear
6. Price (if you do the math it's cheaper than high caps combined)

Cons:
1. Rattles when there are few bb's left in the box mag itself (this can be temporarily fixed by sticking your hand in it)
2. Not good for left handed people (thankfully I am right handed)
3. You need to make sure you locked the mag down (not that big of a con)

- Great Mag; Know How To Use It..., December 27, 2009

I have used this box mag on a friend's ECHO1 E90/P90 and it is a huge help on the field! I strongly recommend it, but you have to know how to conserve ammo. You will have about 1800 BBs in this box mag setup, 1500 BBs in the box mag itself and about 300 BBs in the M4 mag, am I wrong? Psychologically, you will have a couple thousand BBs, which will make you lose your sense of ammo conservation. Even if you are a support gunner, you have to know when to lay off the trigger. You cannot camp inside a pillbox and continuously shoot at the enemy who has taken cover at over 200 feet away. Wait for the correct time to pick them off or to hold them under cover. Keep in mind that you should upgrade your battery and perhaps get an external pouch for a large type, since the typical 1100mah mini battery will only last halfway through the box mag. I actually have personal experience with this whole problem. I got an ECHO1 M249 SAW Para and I loaded up the box mag half way (1200 BBs) to break it in. Literally two minutes later I was out of ammo and battery power! You definitely need some type of experience with a box mag before you use it in battle.

ATTENTION:
If you own any version of the p90 get this(and a mag to use with it).
I have yet to have any huge issues with it and i have used it for a couple of matches since i got it. This thing holds a lot of bbs and when you are playing a serious game you don't really get that trigger happy (in my opinion) so you will not need to worry about reloading. I do not have any problems with my battery (standard echo 1 e90 battery) running out before this or vice versa. then again i have not tried to see which runs out first yet. One small con(note the 4 stars) is that you have to make sure to "slam" it into place or else it will not actually lock into place and it is definitely meant for a righty (which thankfully i am). Not saying lefties can't use it but it may feel uncomfortable. Also i tend to have difficulties putting my mag into this so i find holding the box mag upside down when putting in your other mag into the box mag very helpful. Otherwise this is a definite buy. Unfortunately you can get a box mag that hold 5000rds or a 2500 rd cmag for the same price as this for a different gun and you have to buy another mag to put into the box mag(does not come with one). For some reason i feel that there is a monopoly on this mag since there are no others like it and basically everyone who has a p90 wants this.

- P90 Box Mag, November 04, 2009

--This is a must-have for right-handed P90 players!!--
fixes two of the P90's biggest problems: mag capacity and battery size.
>other P90 hi-caps are 300 rounds, which may or may not be enough depending on playing style. This box mag - unlike box mags for other guns - maintains the P90's sleekness, and possibly even makes it look even cooler. 1500 rounds is also even more than some other box mags for other guns.
>the space in front of the box can fit a Large type battery, so now you don't have to worry about running out of juice (especially if you use 9.4v)

- I've owned this magazine for 2 years, May 22, 2010

Well, as this title says, I've owned this extended magazine for a very long time. This magazine offers 1,432 more rounds than the E90's magazine of only 68, making it a necessity when you're playing. Overall, there are two huge benefits that I can identify from this magazine. One, of course, the extended rounds. But two, the looks. If you only have the E90 and this, it may look a bit odd. However, with my mock silencer, my red dot sight by crossfire, and this magazine, my gun looks like something out of a science fiction movie.

This magazine, as all items have, has its fair share of disadvantages. One - the grip. I feel that this magazine blocks part of my hand. This prevents me from getting as much accuracy on the field as possible (which doesn't pose as too much as a problem if you are playing CQB). Two, the looks. It looks very funny unless you have some other attachments to match it (as mentioned above). Three, the biggest problem that I think this offers is the weight. With the one pound box mag, the .6 pound bullets within the box mag, and the .5-1 pound m4 echo magazine, this attachment adds almost 3 pounds to your gun. As this seems only a little, it effects the gun A LOT while trying to run and sneak through the tiniest openings and holes; especially while crawling.

Overall, the fact that you have 1,500 rounds rather than 68, really does make this a necessity. If there was a 300 round magazine for the E90, I would definitely recommend that over this. However, until then, this is needed for the extra rounds and the fun method known as "Spray and Pray."
