My kit was supposed to be here Monday but arrived yesterday. I tore the rifle down yesterday afternoon and found the chamber and the end of the piston scored so I cleaned up the chamber and put the piston in my lathe and polished it. Today after church I cleaned everything twice and reassembled. The piston seal wasn't as much trouble as I expected. I heated it with a heat gun and worked it on with a small round pick, much like installing a tire on a wheel. The piston, back side of the seal and the spring was lubed with the supplied grease. The pivot sleeve, barrel pivot area, the pins for the cocking lever and the stem of the piston were lubed with moly.
WOW is all I can say, it's like shooting a different gun. The cocking effort is less and much smoother. There is no vibration during or after the shot, just a thwak sound. It still recoils but it's a different recoil, not like that fly on the double bass string lol.
My advice to anyone buying a new 34 is to take it apart deburr and lube it from the start. My factory spring is already bent in two places and the seal had some pretty good gouges.
Now it's time to order a scope.
Thanks guys, Justin
