  • For AAP-01
  • Ideal Spare
  • Fix Gas Mags

A replacement or spare Outlet / Knocker Valve for the Action Army AAP-01 Assassin Pistol. If you own plenty of Magazines and want to keep them in tip-top condition, then you're going to want a few Knocker Valves spare in your arsenal. They are incredibly easy to install, provided you have an appropriate Valve Key on standby. You can use other tools to install them, but this is not recommended as you could damage the Valve.

  • 23rnd Capacity
  • For AAP-01 Pistol
  • Green Gas Magazine

This is a spare or replacement Gas Magazine for the Action Army AAP-01 Assassin Pistol, that holds a total of 23rnds and is based on the EU Series design. It is filled with BBs and Gas just like any other Pistol Magazine, using a Speedloader to feed BBs in through the feed lips, or holding down the follower to fill the BBs from the bottom of the Magazine. The Inlet Valve on the base of the Magazine is where you should insert your Green Gas bottle to fill it.

If you own an AAP-01 Assassin and want to spend more time dumping magazines on Full Auto, and less time fumbling around with a Speedloader, then you will need a backlog of Spare Magazines.

  • For AAP-01
  • Ideal Spare
  • Loading Nozzle

A Polymer constructed Gas/Loading Nozzle for the Action Army AAP-01 Assassin Gas Blowback Airsoft Pistol, which is an ideal spare part to own, and is absolutely vital to the function of the Pistol. If you plan on using Full Auto a lot, then a Spare Nozzle is a must-have, as you don't want to be caught out come skirmish day.
