I bought my first air rifle a couple of months ago.
I didn't realise at the time, but it was a rather ropey 30 odd year old .177 MK1 Anschutz 335.

The stock had a bad finish with brush strokes and runs in the stain, the stock screws were all chewed up, and the original sights had been removed.
I was naive and ended up over paying for it.

I decided to give it a rebuild after it showed 9.5ft/lb over the chrono. Upon stripping I discovered a cut and unfinished spring, no spring guide and a knackered bolt holding the leather piston in place.

I stripped and re-stained the stock with tea.

The fore end screw holes were oval, so I found some top-hat nylon washers and fitted them in place.

A new main spring and ptfe piston seal went inside the action, the stock was finished with tru oil, and a nikko stirling gameking 3-9x40 and slip over silencer were fitted.

(I had to fit a spacer to the stock to get the pull right).

After running the rifle in, a four shot string with JSB exacts over the chrono gave:
774 fps
778 fps
779 fps
775 fps
Which is around 11.30 ft/lb

With three sighting in shots, I managed a nice 1/2" five shot group, with shots three in the same hole!

I'm really happy with the rifle now, even if I was ripped off to start with.
Next on the list is a spring guide and a barrel re-blue.
