Piston lengths
Just to explain the earlier comments ref piston length.. the overall lengths are the same, but the cocking slots and sear engagement points differ..
The one on the left is the regular short stroke, with full piston head and buffer arrangement.
The other two have are long stroke; the sear engagement is further forwards, meaning the piston has to be pushed further back to engage, increasing stroke.
The middle one has been modified to remove the buffer washer - gives about 0.5mm clearance on the cocking slot - too tight really, but this represents as long as you can go for a buccaneer stroke just by spacing the piston head spigot inside the piston body to remove the slack after you remove the buffer washer. I will be changing it to take a diana 28mm parachute seal and see what power we can get out of it

Always looking for any cheap, interesting, knackered "project" guns. Thanks, JB.
