Here you will find tuning and spare parts for the APS-2 platform – a spring-powered bolt-action rifle where accuracy depends above all on the cylinder, inner barrel and a solid trigger. The parts here are designed to give more consistent shots and a sturdier trigger than the stock parts.
From Action Army there is a Palsonite cylinder for the APS-2, and PDI has a 6.01 mm inner barrel of 461 mm for the APS-2 EX with PDI hop-up chamber. In addition there is a cylinder head, a spring guide with thrust bearing for 9 mm springs and a steel trigger set.
What to look for
Model and chamber: The PDI inner barrel is for the APS-2 EX with PDI hop-up chamber. Check that your rifle has that setup before you order.
Spring guide: The spring guide is for 9 mm springs. A thrust bearing lets the spring rotate freely as it is compressed, so it does not twist the piston.
Trigger: A stronger spring puts more load on the trigger parts. A steel trigger set is therefore a natural next step in an upgrade.
