Can't argue with that matey, got 5 standard 50rd mags too to fill my mag pouches so no problem there - locaps do feed more reliably theres no doubt. 8)
Only if theres a 500 rd limit per game I can carry them all in mags rather than a speedloader, and it can even the field a bit against the hicap Thompson brigade! :good:
Now, realcaps would be even better! :D

But I assume from his posts that the hi-cap wouldn't be an issue for realistic rate of fire.

But will it work in a Sten?

I doubt it as most hicaps require the mag to be vertical and the sten mag will be in sideways.

Due to the internal design and the principles of a hi-caps functionality, it won't work with a STEN due to having to have the mag' horizontal, rather than vertical. You might get a few rounds through when the mag is full, but you'll run a very big risk of miss feeding and sudden unexpected detentioning of the hi-cap spring which will lead to definite no feeding.

Yes, as above its not really feasible for hi caps with the sten unless you employ the system used on the P90 horizontal magazines ie a pusher which forces the BBs into the winding mechanism, and I doubt thats either possible or practical in the smaller MP40 / Sten mags. (Anyone tried? :giggle: )

Been given one of these recently and they certainly do feed much better when fitted with stronger ribbon spring.

I used a ribbon spring from an M14 hi cap. The ribbon seems to be made from a thicker metal than the Uzi one so I cut about half of it away before fitting it and it actually end ups a shorter length than the Uzi original, but the thicker material in the M14 spring gives more tension, so you dont need as much.

No, it wont. Did you read the comments from 2009 that are just above Greedo's?
Most hi-cap mechanisms rely on gravity to feed BBs into the mechanism. That won't work on a horizontal magazine.
AFAIK, P90 hi-caps are the only horizontal example out there. They work differently, and are VERY prone to jamming.

Yep can't see an answer to Sten hicaps for the reasons mentioned above. Unless of course you fire it with the mag at at least 45 degrees below horizontal. Just think of the can of worms THAT would open with the HOP unit! :giggle:

Sorry to drag up an old thread but needs must when a guy needs mags for his MP40.

In relation to the conversion, I'm a bit unsure of how to fill the converted mag. Do you fill from the feed hole (ie back down into the hipcap mechanism?) I am about to order a couple of Uzi mags and want to be 100% sure of what I'm doing. I'm sure I can complete the conversion but like to certain before I start chopping things apart

thanks
