Pmag/CAm15a4 problem

[tygr701]

When I fire off a few round in semi/auto some extra bb's will gather just below the hop up chamber. When I remove the mags to change them 2-4 bb's will fall out. Anything I can do to remedy this? I've slightly lubed the hop up chamber and the pmags themselves. Thanks for any help.

This is how most AEG's work. There are solutions to the problem, but the easiest one is to let them fall.

Nothing you can really do about it, unless you want to reload your aeg upsidedown so they don't fall out.

There is a hop up mod, involving cutting to notches in the feed tube and putting an o ring over it so the rubber protrudes into the feed tube through the slots, but it's tricky and really not worth the chance of ruining your hop up for the sake of a few BB's per reload.

Also lubing your hop up chamber is only going to work against you, you're going to lose spin on your BB's and lose distance and accuracy as a result..

Alright thanks for the tips guys. I was just wondering if it was just my gun or if it was a typical occurance.

All mags will do this, it's basically because the follower isn't long enough to push those last four rounds into the chamber. I only know of one gun that doesn't have this problem, which is the Crosman Stinger R34.

Your best bet is to either over-load your mags with an extra four rounds(possible with STAR green label PMAGs), or adopt a Costa-esque reload. Both of the above work for me, hopefully they'll work for you.
