Action Army AAP-01 Magazine Lip Set

Magazine lips are a wear part and nobody tells you that until one splits. They hold the top BB in position for the nozzle to collect, and when the plastic spreads or cracks the magazine starts feeding two at once, or none, and you spend a game blaming the hop.

This is the set for the AAP-01 magazine, listed by Action Army as parts 75 and 76. Replacing them is a lot cheaper than replacing the magazine, and on a platform where a drum magazine costs three figures that is worth knowing.

It is a strip-down job rather than a field fix. Plan it for the bench, not the safe zone.

Specifications

Good to know before you buy

Action Army publish no material or weight for this set, so we are not going to invent one. What is stated is the fitment and the part numbers.

Work out which magazine is misbehaving before you order. If all of them double-feed, the fault is more likely the nozzle or the loading nozzle than the lips.

The magazine has to come apart to change these, so set aside bench time and somewhere to put the small parts.

Buy the set rather than one lip. They wear together and a new lip against an old one feeds no better than two old ones.

Frequently asked questions

What are parts 75 and 76?
Action Army’s own numbering for the two magazine feed lips. The set is listed under both numbers.

How do I know my lips have gone?
Double feeds, or a BB rolling out of the magazine when you take it out of the gun. Both point at the lips rather than the hop.

Is this a straightforward job?
It is a bench job, not a field one. The magazine has to be stripped, so give yourself an evening the first time.

Does it fit the drum magazine as well?
It is listed against the AAP-01 and AAP-01C magazines. Check your drum magazine before ordering, and ask us if you are unsure.

What is it made of?
No material is published for it. Action Army put out a parts list and diagrams rather than a datasheet.
