P90 Hicap wont fire whole mag?

[Pinkette]

Hi Guys

I have a couple of genuine Tm hi-cap p90 mags.

Now i know they are hit and miss etc but: these mags will only fire 50 or so rounds then need winding.

Is there anything i can do to fix this? I was under the impression that they should shoot the full 300 in one wind?

Thanks

Make sure they are fully wound up.
When they hit the limit the noise changes from a 'tick tick tick' to a 'tick kerchunk tick kerchunk'.
If you are already doing that then its a design issue of the frankly p1ss poor P90 mags, cure would be to wind it whenever possible.

a bit of lube in the mech always helped mine.

Thats because they are terrible and very unreliable magazines. Sell them and buy some midcaps.

Been running a P90 for 10 years. What you said doesnt change the fact hicaps in general are shit, let alone P90 ones.

I conclusivley say they are shit

Dont fill them right up make sure they are lubed and wound up fully. No problem.
Saying that I used the box mag and a battleaxe auto winder.
Hypocrite?

Theres a thread in the electric tech forum where I posted a diagram on how to mod a P90 hicap to be reliable. Can't find it at the moment though. Essentially the problem is the BBs can go the wrong way around the loading wheel

failing that buy some MAG 190 round midcaps

Thats for the answers! The mag do wind properly and click click click. But they dont fire more than 50 or so rounds. Not sure if it was the hicap winding spring?

Re: P90 Hicap wont fire whole mag?

Is it actually running out of spring power, or does it suddenly unwind the spring?
If it's the latter, it's the common jamming fault with P90 hi-caps.
