Thanks Bruno. I am going to polish the inside of the tube and the outside of the piston, hopefully that will help. I think there may be rough spots inside from the machined cutouts.. I hope it is that simple lol.Originally Posted by Bruno27
I had the same problem on mine and did the same as you did. I took the opportunity to replace both breech cap o'ring. I had measured 15N IIRC to get the piston to move. I had put it down to over doing it with dry firing (to size the PTFE piston seal). I just use it as it is now and gave up trying to get that extra ftlb.
