Re: Converting mid caps to low caps
Silly answer here but could you not just put 30bbs in it rather than 120. Shore some one will be around to give you a better answer

Re: Converting mid caps to low caps
Yes i could but i was asking if they could be made to be perminent 30rnd as speedloaders are very inconsistant sometimes 3 bbs go in sometimes 4 or 2 go in and i cant be arse to count every time i load up, i can see the buy some low caps comment coming i want to keep these mags due to the high quality finish and reliability, keeping reliability is a question im including in the post above, is it possible?

Re: Converting mid caps to low caps
That was going to be my question too.
If you really want to, then I guess you need to block part of the feed tube and shorten the spring to match. It would probably be easier if you took the spring out and measured it compressed, then worked out the difference between 120 rounds stacked and 30 rounds [(120 x 6mm)/4] and used that as a guide for how much space there needs to be in the tube.

Re: Converting mid caps to low caps
I know sorry didnt meen to come across as a smart arse just wondered if there was a reason behind wanting to convert them i would go for opening them up and blocking the feed tube fitting a spring from some cheep real caps or cut the springs that you have, you could even go as far a cutting the tube to fit a thin slither of plastic in so you could take it out again going back to mid caps

Re: Converting mid caps to low caps
It should be pretty simple.
120 BBs of 6mm take up a length in the feed tube of 720mm. So 30 will take up 180mm. So, as a first attempt, block 540mm of the tube with something that is both flexible and removable if you get it wrong. You can then adjust as required.

Re: Converting mid caps to low caps
A pipe cleaner with masking tape to fit the hole to stop the spirng sliding back would work to get you the length. real blue peter moment.

Re: Converting mid caps to low caps
Figure out where 30 bbs will end in the feed tube, drill a small hole through the feed tube and put a pin in. That way the bbs will only go as far as the spring is compressed up to the pin, and when you want your mids back nock out the pins and hey presto back to mids
