AAP-01 Spring Upgrade Set

Finally, the gap for full aftermarket support has been bridged by Jefe's Airsoft Solutions. Until now, these parts have never been sold aftermarket. If you lost or broken one of these parts, your AAP-01 would be unusable or you'd have to order directly from the manufacturer which could take months. But with Jefe's Airsoft Solutions, you can now easily replace any missing or damaged parts and quickly get your AAP-01 back in action.

This kit contains the following upgraded springs:

Hammer Spring, part 55

Fire Pin Spring, part 88

Fire Pin Lock Spring, part 46

Upper Lock Spring, part 42

Bolt Catch Spring, part 35

Magazine Release Spring, part 37

Safety Spring, part 26

Each Spring is crafted with SS304 wire, the same as our renowned Trigger Spring, Nozzle Spring, and Auto Sear Spring!

SS304 High Grade wire which is a general-purpose stainless alloy typically composed of 18% Chromium and 8% Nickel. It is the most widely used stainless steel wire because of its high corrosion resistance and good tensile strength.
