Single stroke pneumatic rifle? (are there any?)

[Blackrider]

last I heard of the webley was the designer touting to the Chinese gun makers. that was a few years back.

Saw the Paradigm at a Shooting Show somewhere and was not overly impressed. It was alkward, unweildly and tricky to cock. It simply didn't look to be a practical design and wouldn't be a commercial success.

Quite ingenious, amazing nobody thought of using two levers before, should be a winner. He better get patent

Agreed, plus with two levers, you're tending not to 'bend' the tube as applying equal pressure on each lever (in theory )

It's not a new idea...been produced in pistol form with the Feinwerkbau 102.

It didn't last long though before they reverted back to a single lever - not sure why though.

Just wondering what the output would be if a fwb 600 or similar ssp 6ft .177 rifle was converted with a barrel change that had a longer barrel in .22, both being more efficient. Would the output bump up to near the 12ftb limit?

Interesting thought, anyone want to give it a go ?

No.

But I recently bought a Parker Hale Dragon without a pump arm and stock.

I don't take delivery of it until April though.

I doubt it.

.22" is about 20% more efficient than .177". So, if it was originally around 5.5 ft/lbs, a .22" barrel might take it close to 7.

I doubt a longer barrel (and this is already a full size rifle) would add much. Unlike PCPs or CO2s, SSPs don't feature large volumes of unused gas that blows out the front. It's why they are much quieter.

If you want to copy the arm I can bring my dragon down. I promise not to stay more than a week.......

The 600 fwb rifles have a much shorter barrel, the rest is a barrel shroud, a full length 22 barrel at its most efficient length would bump up the velocity a bit more.

I had forgotten that. But I still don't think there is much to gain, given the limited amount of air available.

Actually it is already patented, and not by the fellow in the video!

The patent holder was a character called Valery Pshenychny who used to post over on the yellow forum,
sadly no longer with us.

I tried buying one of the Paradigm prototypes but as far as I know it's still collecting dust in the corner of the office
The quietest air gun I've ever fired was a ssp ...... jb1
I honestly didn't think it was firing at first as all I herd was a faint click of the trigger

That would be great, Steve.

I'll check if my mate Catweazle will be about, he can scan the parts and machine them on his CAD mill.

You know you're always welcome to stay here as long as you like.

Somebody has just made a new SSP prototype.

19 ft-lbs and looks very easy to pump

That is just brilliant.

Dragon is by far the easiest to use i.m.o and the most 'recent ' but many Dragons need reseals -thankfully a few guys out there who do this . Mohawks - harder to cock so say .
