FWB FWB 300 .....anyone else have one?

[Jtrew1984]

Got this one in the mail today. Ordered new breech seals because… dayum. I will conduct a full disassembly when I get some more tools later. What do you think would be the result of shooting it as is? Could I do further damage? I’m assume I’ll get horrible power. Think debris could damage the rifling on the barrel?

I bought this FWB300 as part of a package deal. It is a very rare gun ....apparently. I tried a Google search and turned up very limited information on it.
So, I'm reaching out to our community for some feedback about this rifle. Any information is welcome.

Thanks in advance!! JC

Short or long cocking lever?

Most accurate spring piston rifle on the planet, IMO.

DON'T EVEN THINK ABOUT SHOOTING IT in this condition - YES it will damage the gun. There's no breech seal at all, and I guarantee the resilient bumper pad on the front of the piston bumper is toast too. You'd be slamming metal on metal, and blowing even more plastic chunks down the barrel.

It needs to be completely dismantled, checked, cleaned up, and rebuilt.

I have a question about my FWB 300. The ones imported into the usa in the 70s & 80s, were they using the so called uk power limit then?
I think today anything over 9 foot pounds, is a no go in europe without a license?? What power is usual for these rifles? And is there an after market spring? As i ordered new springs and seals from Europe 6 months ago when I rebuilt it.

No FWB300 made anywhere was near the UK non FAC limit which is 12fpe.

After January 1, 1970, power of airguns sold on the open market in Germany was limited to 7.5 joules, roughly 5.5 foot-pounds. They are stamped with an "F in pentagon" symbol (F = "frei," indicating free to buy without license). This translates to around 600 FPS in .177, which is typical for match guns. In those days (maybe still?) the UK limit was 12 foot-pounds for rifles, and 6 for pistols - not relevant to these guns.

The FWB's swept volume can't realistically be boosted much past that, but Jim Maccari makes (or used to at least) a single spring which ups power a bit at the expense of some firing smoothness. The OEM powerplant is two short springs, wound in opposite directions, and joined at the ends to reduce vibration.
