Re: Air Rifle Stock Help

hey mate if you make the stock out of multiple layers then you can use a router and a straight fluted bit to cut out space saves you messing up with a chisel .

Re: coaxial so far need some help.

so the piston should be tight fit but easily moved.
the plastic bit (isn't a support) should be smaller than the piston.
the barrel supports are made of small plastic washers glued onto the barrel.
i will take pics keep u guys updated :)
