I saw this gem on Trademe this afternoon at a very attractive buy now price and couldn't resist grabbing it.  Looks to be in really tidy condition and will be subject to a tear-down and 'tuning' using all of the knowledge () that I've gained recently from molesting my poor little MIC gun...

Hi Kruza.  Yes it's been finished for a while now but being a typical Gamo, it shoots like crap so I didn't bother with a follow up.

A couple of pics below showing the archillies heel of these guns - the plastic breach assembly!  On this model it also plugs the end of the cylinder, held in place with a couple of solid press in dowels and sealed with an O-ring.  Soooo, the whole breach flexes! And of course, the barrel can close in a slightly different position each shot due to the plastic to plastic contact. 

This means that a red dot or optical mounted on the cylinder is a complete waste of time, and even though my eyes are shot I can shoot better groups with the original open sights.

I stripped the whole thing back including removing the coloured varnish from the stock which I simply re coated with several coats of True Oil.  It looks a bit weird in the lighter timber colour but the finish is pretty good, better than when I received it.  I made up a new steel piston assembly to replace the crappy plastic one and fitted a new seal from Youngs and a spring from AliExpress.

Last week a colleague at our local club was bemused with the poor grouping of his later model IGT, but when I saw that it also had a plastic breech assembly I was able to give him my well informed 2 cents worth
