Feinwerkbau 127 1975

I have the V-Mach spring and kit in my FWB sport and was easy enough to get the spring back in with out a spring compressor,as gary has mentioned.
The spring was also a nice snug fit on the rear steel guide.

Thank you so much. 👍

"Ahhh, almost forgot the important part--how I adjusted the trigger. Here's the procedure: Turn the trigger adjustment screw in all the way. That will give a 2-stage but heavy pull with a very definite second stage. Back out the screw about a half turn at a time until you feel the second-stage get lighter--eventually, it'll disappear. Turn the screw back in--in quarter turns if necessary--until you can just feel the second stage pause. That's about as light as it'll get and still give the 2-stage feedback."

Here's my 124 in "the compressor"

Brilliant idea. My drill press is bench mounted so probably not enough reach. Great thinking though. 👍

Probably the very best FWB 124/127 springs are from Jim Macarri in the ÚS. You can probably find a cheaper one in the UK though.

I'll second that , their piston seals are good too but the one I just fitted needed quite a bit resizing as it was far too tight robbing 100fps off the power of my 124m the one in my mk2 124 I had had a perfect fit without resizing.

JM makes most of his seals oversize so they can be fit to a wide range of tubes.

Really ?i was under the impression the green seal which I have were a standard size & he does a red oversized one for slightly larger tube dia's that some of the mk1's had.

Is maccari still in business? He used to do fwb tune kits and often had spares

He does different sizes for some guns but a lot of his seals need sizing.
