Serious question.

Have there been any technological advances in springers in the last 30 or so years?

I mean:

- Recoilless or suppressed recoil technology: it all dates back to the improved variants of the 1960 or so M&G Giss System (Park, Whiscombe), or copies of the early/mid sixties FWB sled (TXSR, Diana 54/56).

- Gas-piston: nothing really new since the 1982 early Theobens, which most of us think are better than the later HE ones.

- Conventional: toss-up between the 1984 HW77 and the product-improved TX from the very early 90s. The Umarex "Walthers" seem to mirror, rather than improve, on their designs.

- Weird: electric cocking Rutten/Browning Airstar. Not a success. Funny bullpup Chinese sidelever - ditto, but only a cosmetic and ergonomic change, still a standard springer inside.

- FAC power: lots more guns now, but same formula as the 80, AA PE, Webley Patriot. Big cylinder and very long stroke.

And, if I'm right, what might be a proper innovation for the makers? Maybe 22mm bore 12ft-lbs boingers?
