    N/A Smallest/shortest nitro piston

    Pretty much. I was looking at the pneumatic struts/return systems (Softer than Spring(tm)) and thought... double the width of the piston, half the length, higher deltaP over D... But yeah, the website I used to get parts from went defunct/bought out and now can't buy as aconsumer the small...

    N/A Smallest/shortest nitro piston

    I don't believe I'll find anything, but does anyone have knowledge of oddball / designs where the nitro piston is 'fat' compared to standard, and uses that extra volume to reduce length (making the pistol, well shorter but slightly wider)? Saw the thread on the PCP one, and even then it's...

    .30 smooth bore replacement for Hatsan 130S Vortex

    Good Morning- Yep, I'm new. I absolutely adore my .30, even if finding pellets has proven to be practically impossible- and finding 'green' ones completely impossible. So to make things interesting I'd like to turn it into a shotgun :) Or at least have the ability to do so. I reached out to...
