Thanks AT

Congrats on the .22 MM tuned B-26-2

Sorry haven't located a supplier that sells BMK stocks seperately....

Since I'm very happy with the XS-B28 I purchased 2 Xisico XS-B12's from Mike, and a scope and pellets.

The .22 is for a friend, I'll keep the .177.

Only had time to take them out of the box and take a few shots, very busy at the moment, they look great, easy to cock

Made this video a week ago, polished the piston's cocking notch today which improved it a lot.

Sweet rifle

The Quest has been sold, bought a Xisico XS46U from Mike @ BestAirgun instead, arrived at Dutch customs, hope it will be delivered next week

Better picture

Received the Rap4 12 gram quick change adaptor today and could finally test the rifle using Superdomes / no modifications:

Average shots 01-10: 609,3 fps 6,84 fpe
Average shots 01-20: 595,4 fps 6,54 fpe

Pitty I'm on 24/7, hopefully tweaking will start next week.

Once tuned will switch to 88 gram.

Bought two oldies today, the springer looks nice for it's age, feels like the piston seal has gone, the pumper is rather tatty, barrelband/sight missing.

Did the basic tune last night, didn't feel like checking tp mod and probe mod seperately.

Allignment valve/porthole was ok.

De-burred screw-hole inside breech to prevent barrel o-rings from clipping.

Fitted new o-rings on barrel, lubed with silicone grease the o-rings came in.

Enlarged probehole, ellipse shape forward direction.

Fitted new o-ring on probe, lubed with pellgunoil.

Lubed bolt (thin coat nd-oil)

Replaced transferport seal after cutting off a few mm first to prevent it from crushing.

Reassembled rifle.

First shot: tissue over breech, not a whiff of co2 from the top nor sides.

Before tune / 12 gr co2
Average shots 01-10: 609,3 fps 6,84 fpe
Average shots 01-20: 595,4 fps 6,54 fpe

After tune / 12 gr co2
Average shots 01-10: 678.7 fps 8.49 fpe
Average shots 01-20: 659.3 fps 8.02 fpe
