Air Venturi Feinwerkbau (FWB) Seal Kit, Breech & Piston Bumpers, Fits FWB 150/300

Fast delivery, well made reproduction

You need to add the metal piston seal ring !!

This does NOT come with the metal piston ring (seal) I could only find it in Canada for over $27.00

Restores the function of my FWB 300 Universal to like new function. The new material the seals are made of seem to be firmer than the original material. I am pretty sure that material science has advanced in the last 40 years since the rifle was made.

Nothing to change, the seals work as designed and restore function to the airgun.

This seal combination can be hard to get. Consider having a set available in your kit. When the originals go your fine airgun becomes a tomato stake.

This seal kit fits the FWB 300 perfectly. Shooting performance after installation is excellent and has restored the air gun to like new state.

Nothing, just fine as provided

The FWB is not an easy rifle to work on. This high quality kit will mean it only needs to be done very seldom.

These seals are hard to find and Pyramid Air had them - - it was the only way I could get my Feinwerkbau 300S to work again so they were critical. Top notch quality seals and the air rifle shoots great again.

This part was exactly what I needed. It worked well.

this part fitted inside a small envelope. Why did it cost almost $8.00 in postage and take almoat two weeks to get here?

you inventory concerning FWB parts should be posted in your catalogue

the parts fit and seem to be O.K.

These are U.S. made repro parts, priced as high, or higher, than the readily available German originals.

The parts are grossly overpriced and there is no excuse for not changing this ASAP.

I bought the kit for spare parts and the breech seal. It all appears to be a perfect fit.

You get the special wrench you need to take the valve out of the gun. You get all of the seals you need.

A little more detailed set of instructions on handling procedures to reassemble it.

The white Teflon check valve disk has a radius on one corner. No mention in the instructions as to which way the radius should go in. (facing front or back)

I like the idea that these parts are available.....

There are 3 parts that make up the sealing system in a 300 ( breech, bumper and piston ring...for $30 bucks and $8 bucks shipping ....wouldn't ya think they'd throw in a piston ring?....no-o-o-o...you gotta go hunt it down else where ....and pay through the nose for the part and the shipping bend over yet again....SELL ALL 3 PARTS TOGETHER...and ease up on the shipping for small parts.

This is the Pyramid way...

I recently rebuilt three FWB 300's, one in pieces. The seals had deteriorated completely. These were easy to install, and I had them in in very short order. The quality of the seals was high and they functioned perfectly.

nothing

If you don't feel very comfortable with a fairly complicated build, and don't have a spring compressor,don't attempt to install the piston seal yourself. Have a competent airgun gunsmith perform the service.
