...as usual, eGun is a brilliant place to pick up stuff like this Fwb *MINT* P70 Running Target.. Project Plan (have received Fwb price quotes for parts) 1. Fit 15J chamber plate 2. Fit 15J hammer & spring ; fiddlle regulator & use chrono. 3. Try out gun with existing barrel at 10m, 20, 30, 40 50 yards etc... 4. If groupings suck, use Fwb spare barrel holder, to have custom made barrel fitted...and try groupings once again.. 5. Try & source/get a Fwb Junior stock as well...(ideal is gun like last 2 pics).
