- description
Put a lightweight bolt in an AAP and the cycle gets quicker than the factory nozzle spring can keep up with. The nozzle does not return fully before the next round is asked for, and what you feel is a misfeed or a dead trigger pull in the middle of a burst.
This is the fix: a 200 per cent rate spring wound from SWP-A music wire at 0.400 mm, annealed and chromium treated, made in Japan. It returns the nozzle harder and faster so the next BB is picked up cleanly.
Two come in the packet, which is sensible for a part this small and this easy to lose on a bench.

Good to know before you buy
This is a 200 per cent spring, which is a lot. If your gun is otherwise standard it may be more than you need and a 160 per cent would do; this is aimed at builds with a light bolt and a strong recoil spring.
A harder nozzle spring asks more of the gas. Expect to re-chrono and possibly to adjust pressure if you run HPA.
Two springs per packet, so you have the spare before you drop the first one.
Frequently asked questions
When do I need a stronger nozzle spring?
When the bolt has been lightened or the recoil spring uprated and the gun starts misfeeding in fast strings. That is the nozzle failing to return in time.
Is 200 per cent too much for a standard gun?
It can be. On an otherwise factory AAP it is more spring than the cycle needs, and a lighter rate is the sensible first step.
What is SWP-A wire?
A Japanese music wire grade used for springs that have to take a lot of cycles without losing tension.
How many are in the packet?
Two.
Will it fit the AAP-01C?
Yes, the nozzle assembly is the same across both frames.
