Description

I have been asked on numerous occasions to make a kit for the excellent Feinwerkbau Sport 124 /127. I have designed this new kit to breathe new life into this sporting classic. The kit I recently designed I have been testing & has given superb results, with a new piston seal fitted and over 30 shots it averaged 5.2 fps variation this should improve as the kit beds in power output is 11.6 ft lbs with virtually no recoil.

I Have been told this kit will also fit the FWB MKI as the only difference is trigger is plastic not aluminium as on the MKII.

There is currently 25 – 30 working day turn round time on all WW Kits
