This started off as a non-pal TR77 NP. They are very hard to cock. I swapped in a shortened quest spring. It has delrin spacers to take up the slack in the spring. Zero preload. Easier to cock than a stock quest.

This spring and piston set up were in my wifes Quest which I built to be easy for her to operate. She never uses it so I put the guts into a almost new TR77. The TR77 has better finish then I have seen on other B18 guns. The stock is from my Phantom, and is in good shape. Would be a bit smoother cocking with a few more coils cut off and a larger spacer used.

Asking 120.00 shipped, or will trade for Chinese rifles like a B3-1 sidelever, B3/4 underleaver, XSB9, or ????
