I've just noticed that quite a bit of people claim P90 hi caps can release all 300 rounds on one wind...though mine clearly hasn't been able to do that. Usually it'll kick out 95 or so rounds, and will need to be rewound. Is there some sort of break in procedure to get all 300 rounds out?

What brand is your hicap? Not all P90 hicaps are made equal.

So much THIS.

Ah...good point, my bad for not being specific. I run JG/KS/China hi-caps.

Going further on my statement, not all ACM P90 hicaps are made equal either. I have two ACM P90 hicaps. Both are fairly old (if it makes any difference). One of them, just to see how well it worked one time, I dumped a mostly full (probably around 250-280 rounds) magazine in one or two long bursts on a single wind. I then proceeded to do the same with my TM hicap as well with similar results. The other guy that was standing around told me I was going to strip my piston. Fortunately, it hasn't stripped yet. I can't recall if the other ACM hicap works as well, nor can I actually remember which of the two I did that mag dump with.

Or, another time during a game, I had my 3 P90 hicaps on me. I was firing, and the BBs jammed up in the magazine, causing the magazine to completely unwind. I quickly changed my mag, continued to fire, and the second one did a similar thing shortly after. I changed mags again, and if I recall, I had forgotten to wind that mag, so I just held back and re-wound up all my mags.

What would be nice is if there were some easy way to rig up a P90 hicap so that it had a similar mechanism to those flash mags. That way, you wouldn't need to worry about when it unwinds itself or needs to be wound up again for whatever reason without having to take it out of the gun. The other solution is to do what I've mostly done (though I haven't been out to play since I did so), and switch to the MAG midcaps. No more issues with unwinding mags, physically they feel more durable, and you're only losing about 30-40% of your capacity, that is if the mag feeds properly in your gun...

As for fixes for the hicaps, is it just that it can't unload all the BBs in a full wind, or is the loading wheel skipping BBs every now and then, meaning that your magazine is essentially unwinding half of the time without actually loading a BB? There are some possible fixes for that second issue floating around, and for the first issue, it would be more of a matter of fiddling with the magazine to see if you can't get it to store more energy in the winding spring. It's hard to diagnose without fiddling with it, getting a better understanding of what it's not doing correctly.

Not exactley hwat you are asking for but p90 high caps have a hex shaped hole that you can put a 3.5mm hex key into to wind just fine, just like the JG m4 hicaps. I would try spraying a batch of bb's with silicone oil and run it through the mag, then wash the bb's and run them in a couple of times again to break in the mag.

As for the unwinding when putting the mags in, make sure when you are reloading that there is not another round in the chamber already. The p90 mag is able to release a bb before the mag is seated fully and thus can unwind like that, I learned to do a Chris Costas and twist my gun when reloading to toss out any errant bb's and slap a new mag in. And I do mean slap.

I got weird looks from people I play with when I claimed I could get a full mag with only one wind but I have always had a full highcap per wind, no matter what platform so no clue why people think otherwise.

There are some other mods too, to prevent the mags from jamming up, I think it was to prevent 2 bb's from entering the winding mechanism at the same time. Google it.

Actually, the size varies between different brands, and the difference is the slight difference between SAE and metric. If I recall, the TM and CA hicaps used 3mm and the ACM used 1/8". The 1/8" will not go into the ones made for 3mm without forcing it in, causing the plastic to slightly deform. It still doesn't get around the fact that you need to take your mag out of the gun to wind it, but yes, it would make breaking in the mag easier.

If you skip in to about 7:30, it shows the slight difference.

I dislike the P90's mag system also, I still don't see why they didn't incorporate at least a side winding wheel into the magazine instead of a receiver facing wheel.

The hex-key winder I know is a quicker way to wind, but mine is actually starting to strip itself off into a circle o_O. Tried both my metric and SAE sets, and the best fitting one is still loose enough so as to discourage me from using it further.

My high-cap again, pretty much just unloads only 75 or so rounds. It's the version with the small metal flywheel though, not the original ones without that that apparently had random unwinding issues.

I could make an educated guess: TM generally makes their models as accurate as possible, including the magazine, especially for appearances, particularly the standard mags. The outer shell of the magazine is the same between the hicap and the standard mag. If they had to make a different shell to accommodate some other winding mechanism, whether it be on the side or the top, that would mean they would need to make another mold which would cost extra money. Then, the companies that cloned it decided to just copy TM's design, rather than "improve" upon it.
