Joe I can  help you out.
Just drive on up to R&L  and face the Jkhan thus causing you to break Jkhans hold on you.
Remember to document this moment so you can look back and be proud if yourself. And post it to be an inspiration to us all.
( not working hu)
Fine then go to Randy's take pictures to make us drool.

It cycles the pellets really well. Action is really smooth. One of the mags had one hole that had a burr and after filing a little it was fine.

Dave

You can adjust the power by putting in a lighter or heavier hammer spring in.

The 'big screw' that holds the hammer spring in can be adjusted inward to increase the tension but can't be adjust outward because of how the stock fits.
