Found a Feinwerkbau 124 Sport

[Nod]

Just purchased a 124 Sport that hasn't been fired since the early 80's so it looks like I'll be learning how to replace the seal & spring and doing a home tune. I'll probably be asking a lot of questions on this project but I'm sure I'll find the answers from this fine group. Cosmetically, it looks fine (from the pictures), I didn't see any rust on the bore. It has the plastic trigger and the serial # is 10886 so I know it's an old model. Can't wait to get it !

Great rifles ... Yea few of us have them and happy to assist if needed

Thanks Scott, I'll be needing recommendations on a tuning kit for sure.

Link above is the place !!

Honestly not sure which kits best, but experience tells me somewhere middle of the road and not a MAX power kit ?

I've bookmarked the link, thanks.  It will be interesting to see exactly what kind of shape it's in.

Get the mongoose seal and a lube kit. With little use, the spring may be aok. You can always purchase a JM kits or the drop in wire later on. Sometimes it takes a few 'tunes' to get our rifles "just the way we want them". Have fun and enjoy

The above advice sounds like your best option. Let us know which path you chose.

Hopefully everything will be alright.  But if it is an original piston seal it may have melted in the cylinder.  I have a friend who has a 124 with that problem.  I was hoping someone could suggest the best way to clean out the cylinder.  Thanks

They don't really melt - just crumble into a big mess.
I used a wooden dowel to dig out the majority. Then I sharpened the end at a slant so I could reach the edges. Just make sure that you get all of it out.

Great find you made on that FWB 124.  I have two of them, one with a Maccari ProMac tune kit from Air Rifle Headquarters, and the other with the stock spring and seal.  The stock one is doing about 750 fps with a 7.9grain pellet, while the other tuned one is doing closer to 850fps.  I definitely get good power with the ProMac tune kit I put in it.  However, if i were to do it again, I'd go with the "New Slightly Softer Pro Mac kit".  Maccari says its 5% less fps, but 20% easier to cock.  Here's a link:

Unless you want the most power possible, I think the kit above with slightly lower velocity is a good trade off for the 25% more cocking effort I got after installing the regular ProMac kit.  The really great thing about the FWB 124 rifles is the extremely low cocking effort of about 20 lbs, making it a lot of fun to plink and shoot with all day.  I find I shoot my easy-cocking, original spring FWB a LOT more than the full-powered one.  The new kit is great, and has less noise and the shot cycle is faster and more straight back, but its not as "fun" to cock any longer.  Not that the cocking is hard, its still a bit less than my  Beeman R9 is to cock. 

Just someting to consider if you go the tune kit route.  Just a spring/seal replacement would be fine too and keep it closer to original factory speed, with low cocking effort.    Let me know if you need more info later on.

Thanks, tjk and Mark.  I'm bookmarking all these suggestions and really appreciate the info. The seller is waiting for the paypal to clear and then he will ship, I'm hoping by this weekend.

Congratulations on a cool find. I've heard lots of good stuff about these guns. I've never even seen one though.
