Product details

This SRS/TAC41 piston cup offers a very easy reloading but high joule output while remaining to be silent by adjusting your airbrake properly.

The Stalker High Joule Cup can turn your 2j spring powered setups into 3j setups and 3j setups into 4j setups, for example the Stalker scorpion piston with stock SRS or TAC Silverback spring and 420mm barrel+stalker cylinder shoots ~2j on .48 BB.

This cup works with either in SRS cylinders or TAC41 cylinders. Please use a little bit of oil lubricant for perfect results, we recommend motor oil silicon grease or similar.

For reference, a Blue 2J+ spring is giving 3~ joule in a SRS with Stalker SRS cylinder + 420mm inner barrel.

Stock cylinder will give a little less joule. Results may vary depending on the cylinder being used.

We also offer an extreme silent piston cup which reduces the joules around normal spring output but is easier to make extremely silent.

  • Zero loading friction.
  • Thumb block seal.
  • High Joule Output.
  • Fast Reloading (Lightest pull) because you use a weaker spring but get high joules.
