Product details
This SRS / TAC-41 piston cup offers a slightly lower joule output but is the best solution for making your SRS / TAC-41 extremely silent. This cup works either in SRS cylinders or TAC-41 cylinders. Please use lubricant for perfect results, we recommend motor oil silicon grease or similar.
For reference, a Rapax Lightpull Blue 2J+ spring is giving 2.2-2.3~ joule in an SRS with a Stalker SRS cylinder with a 420mm inner barrel. The stock cylinder will give fewer joules. Results may vary depending on the cylinder being used.
- Thumb block seal.
- Normal Joule Output but extremely silent.
- We recommend buying some spring guide spacers to adjust the joule a bit.
