FWB Feinwerkbau 150 - help needed

[Bear-of-Grayling]

Just acquired this FWB 150. Looks nearly new. Serial number 35059 indicates it’s a 1968 model I believe. Having a traditional stock design makes it suited for either side shooters. And I shoot from the right side. I feel very blessed to have found this rifle in this condition. It Chrony’s in at 634fps using RWS Hobby 7.0 grain. Beautiful Walnut stock. Came with a bipod and adjustable Iris. The only thing it needs is a new breech seal. Does anyone here know where I can get one? Thank you.

If the breech seal (tanish brown, probably original) is decomposing, is it fair to assume that piston buffer is also? I’ve never taken a 150/300 apart. Is it fairly straight forward? Who is a good person to contact if I wanted to send it out? Thank you.

Macarri for the seals, Slade for repair. I would think the same, if one seal is bad likely the other is also. I have never done one but some very inexperienced people said they have. A lot of clips and such but numerous YouTube videos on how to...

Must be a reason there sold as a set to replace each as needed or together.. you could ask arh if he has just the breech seal to sell standalone. I guess they figure if one is going out so is the other so its sold together in a set .

....p.s ....

I think the old fwb seals materials/ formula to make them used back then were easy to degrade . So that kinda adds up to get a set .. maybe .. i guess ..lol

Feinwerkbau 127 (124) Piston Seal Replacement

In Hawaii in 1981, when I was 15 years old, I was heavily into airguns. At that time, I saved up and bought a new Feinwerkbau 127 .22 caliber air rifle. I still have the receipts for it, and all the accessories I bought for it. It was my favorite possession for the next 3 years, until I turned 18...

Thanks Mike. Do you or anyone here have a contact number for each? I’ve never used either one. Thank you.

Beautiful gun. I got two of those earlier this year so my son and I could have matches using identical guns. Equipped both with adjustable iris apertures. I have a newer FWB 300 and prefer the stock on the older 150.
Here if you wish to send it out. David has reworked several FWB guns for me over the last few years Excellent work.
I have a 150 sr 32718 and an email from FWB says it was made in 1968, so am guessing yours about 1970-72

Nice looking example! They are great guns and built to last. The buffer is definitely a weak point, but you shouldn't have to replace the piston ring. Here's comparison pics of a new one and one out of an old work horse club gun FWB300s. No visible or measurable wear. The buffer had crumbled on the same gun.

Looks like you did the replacement yourself. I’m going to do mine also. I have watched a couple videos and it looks pretty straight forward. This gun has seen little use. I can’t see replacing parts that do not need it. The spring and piston ring are still basically fresh. Any tips you can share with me? I see the two trigger screws seem to be the tough spot. Thank you.
