Neil Price is rebuilding a classic target pistol from the ‘70s
Back to the ‘70s as Neil rebuilds an Original Model 6 target pistol
The Original Model 6 was one of the first ‘recoilless’ spring- powered air pistols, produced in the ‘70s, so this one is about 40 years old. This is a break- barrel target pistol and has a twinopposed piston, also known as the ‘Giss’ action. The pistons are kept in phase by a rack and pinion mechanism.
A friend of mine brought this round to me, as pleased as Punch with himself because he had bought it at ‘a bargain’ price from a gun shop, and he asked me to look over it and chrono’ it for him.
So I set up the chrono, weighed some pellets out, loaded it, shot through the chrono’ – and got no reading. I cocked the pistol again, and found that the pellet was still in the breech, and there was a piece of fibre poking out of the transfer port.
I know from past experience of these, that this was a piece of the original (pun intentional) piston seal so it had to come apart.
I asked if he had test- fired it at the shop, but he hadn’t. He paid his money, grabbed the pistol and rushed out. I suppose, if it had been a functioning pistol, he wouldn’t have got it for such a bargain price.
We have covered another variant of this pistol in Air Gunner magazine, but this one is the Target model, and differs on quite a few points in regard to stripping and rebuilding so I decided to write it up. 1 The pistol grips are taken off by removing the two cross- head screws. 2 Remove the two slot head screws shown here … 3 ... slide down and remove the pistol grip/trigger guard assembly. 4 Remove the end cap, slot- head locking screw and unscrew the end cap from the action. 5 These can be tight coming off, so to stop damaging the surface
