Challenger 21

[32:1]

Hi guys
Complete Crosman newbie here looking for some info on the 21 Challenger as Ive bought a sample sent to the UK for evaluation by an importer, they had five samples and I was lucky enough to get one

Id like to find a schematic and as much info as possible as its a great little gun but has an issue of dropping shots and its random, say one or two in a 25card, the shots are low fps from 580’s it will drop to mid 400’s.

Its actually very accurate and the LW barrel seems to be a good one, cocking is firmer than Id thought a 6ftlb gun would be, trigger is predictable but heavy and Ill clean that up once I get some info on the gun as I dont like stripping things without a diagram at least, so Id especially like info on regulator and adjustments, plenum sizes, hammer weight and stroke options and anything in between

Cheers

Chris
