My target rifle project

[Finn]

Thanks for the encouraging comments. I have made some improvements and modifications to the rifle.

-New front sight tunnel with glass inserts
-Ground a set of front sight magnifier lenses
-Designed and built a custom rear diopter sight
-Longer barrel extension with integral silencer
-Paintwork in progress
-Recoil absorber system is now complete
-Balance weights added
-Fore stock height adjusters
-Increased plenum volume and stiffer valve return spring

Pictures show the operation principle of the air operated recoil absorbing mechanism and associated parts, system has two adjusting screws and can be matched to any common pellet weight.

Rear sight and shroud + couple of misc parts are currently unfinished aluminium but all those bare parts will be anodized in the near future.
Rear sight tube has threads to accept filters, polarizers and whatnot, one click turned out to be 0.1 MOA. 

I have shot over 5000 pellets through the gun and so far the only real problems have been one blown regulator o-ring and the trigger had to be cleaned from carbon fiber dust because the gun would not fire. I recently washed the inside of the stock to clean off any dust.

I think black is the color for those new parts.
