cocks nice and easy , maybe a little bit lazy on firing ... going take it apart and look at the spring guide , just wondering now if its got hw77 internals like in a early forum post I read over the weekend.
just for reference how tight does the fit of the spring guide need to be when slipped into the spring , should the spring spin on the guide or should the whole lot spin on the block.
lastly re reducing the stroke , is it as simple as putting a tbt piston extension on to existing piston .
Thanks
