Recoil-less springer

[Craig-P]

My mate Nurek is a good bloke to talk to about Whiscombes. He’ll be along when he sees the title of this thread. He owns some stunners.

Sounds like a Whiscombe, I had a JW60 which required two strokes to cock, the same as the JW50. The higher power ones do require three strokes.

Very nice guns, regret selling mine.

Three that I know of, Park, Original, Whiscombe, have two pistons to dampen recoil.

Whiscombe is the only twin opposing springer that's cocked twice and the only twin opposing piston gun where both pistons produce power, hence capable of over 30ftlbs (as in the sum of two normal spring guns).

The other guns mentioned such as the Park use the other piston as a counterbalance (to balance the recoil), not to produce power, hence can just about produce 12ftlbs and to be honest they struggle to get there anyway.

The guns are not exactly 'dead' to shoot as there is a lot happening mechanically, but the more powerful guns have a similar firing cycle to their FAC counterparts.

JW80 is the most powerful Whiscombe and is cocked three times, the third stroke cocks the trigger, the powerful Whiscombes can be hard to cock, just like a FAC airgun would be.

The 80 indicates stroke of the piston as in 80mm.

John made the guns capable of FAC levels as the biggest market is in the US and of course they like their power there whatever it's air or powder.

I think the Park rifle pistons may be both compression like the Whiscombe. If you look at the transfer port where the pellet is loaded, it is at the mid-point where the pistons meet. That's probably why the power output on them was superior to the Original Giss system.
