AAP-01 standard magazine spring too weak?

[BRThoughts]

I bought myself an AAP-01C pistol and it’s great but the BBs don’t feed right to the top of the magazine.  Much fiddling and different BB brands have made no difference.  Are the stock springs on these crap and should I look for a better one? Are the tolerances in the top plastic part too tight?  Has anyone else had this issue and figured out why it happens?  Thanks for any info.

I'd say that there's something wrong with the feed lips, the BB can't into them, rather than a spring problem.

The original AAP mags do have weaker springs in comparison to, say, WE (coincidentally I was loading examples from each manufacturer this afternoon ready for tomorrow's game and it is noticeable). But I'd agree with the above - something not right with the feed lips.  If you have ruled out the bb follower catching/rubbing in the channel, then probably worth taking off the lips and giving them a gentle sand where the bbs feed through...

Yup, what they said. My AAP-01C's magazine feeds fine (and it will eat Action Army and WE mags). Get in there with a file or some rolled up sandpaper.

I used the rolled-up sandpaper technique to smooth the inside of the lower feed lips and it seems to have done the trick.  Thanks everyone.  
 

Now I have another issue; every time I rack the slide a BB literally falls out of the end of the barrel so if you pull the trigger the chamber is empty and it just dry fires.  They just go right through as soon as they enter the chamber.  Any thoughts?

Try setting the hop for that, Ive seen that before and adjusting the hop sorted it

Thanks for that link Mik3F.  Like it says in the vid AAP seems to ship with hop turned off.  Adjusted it as described and now it’s snappy as hell.  Thanks mate!

No worries, glad it worked

I had to do the same for my lads AAP
