B21 Power.
« on: July 09, 2009, 07:53:49 AM »
Can anyone tell me what kind of power a new B21 would put out? And also if it would be easily knocked down to sub 12ft/lbs. Any help would be appreciated.

Cheers, Graham.

they are usually in the 900's in .177 IIRC, you can detune them but then have to lighten piston etc. to get them to shoot smooth....
