CTM Tactical Spare Spring Set (9 Springs), AAP-01/C

The CTM Tactical Spare Spring Set for the AAP-01/C brings together nine of the small internal springs from the Action Army AAP-01 and AAP-01C in one pack: hammer, hammer sear, auto sear, magazine release, bolt release, fire pin lock, trigger, safety and upper lock springs. The springs follow factory specifications with no increased spring force, so the set is used to restore the pistol's original function – not to tune it.

The AAP-01 is one of the most modified GBB platforms on the market, and it is precisely the small torsion and compression springs in the trigger and hammer group that most often fly off or get tired during disassembly and rebuilds. With a complete set in the drawer, you can replace a single spring straight away – or replace the whole lot on a used pistol so all springs start from the same point.

Features of the spring set

Advantages over buying individual springs:

• Nine springs in one pack: Covers the hammer, sear, trigger, safety and release functions. Recoil and nozzle springs are not included – they are available separately in both standard and upgraded strengths.
• SWP-A music wire: The manufacturer specifies the material as SWP-A music wire of Japanese origin – a Japanese standard for high-tensile spring wire that holds its tension better than unknown soft steel.
• Factory specification: The same spring force as the original. This means the trigger feel and hammer strike are unchanged, and no other parts need adjusting.
• For AAP-01 and AAP-01C: Fits both versions of Action Army's platform, as they share internal mechanics.
• Cheap insurance for rebuilds: Small springs are easily lost when the hammer housing and trigger are stripped – with the set to hand, you won't get stuck halfway through an upgrade.

Maintenance and safety

• Remove the magazine and check that the pistol is empty before disassembly.
• Work over a tray or inside a bag – the torsion springs in the hammer housing are under tension and can fly off during disassembly.
• Take a photo of the springs' positions before removing them, and lightly lubricate moving parts with silicone oil on reassembly.
• Fitting hammer and trigger parts requires some experience – our workshop in Aulum, Denmark can handle it if you prefer.
