I got a Uberti spring to replace the broken one in my Remington #2 rolling block rifle.  This is the one with the little semicircular jog in it to clear the trigger screw.  VTI Gun Parts has them.  The spring fits, and functions perfectly on the trigger side.  It doesn't have quite as much "snap" as I'd like to see for closing the rolling block, but it has enough to work, and it keeps the block up for firing.

Too bad Uberti didn't make the breech block end of the spring just a teensy bit longer, but their version definitely works better than anything I could make.  I got an extra one, just in case.

Hard to go wrong with Rollingblockparts. com    You can even talk to Ken on the phone.  Very helpful.  He had some #2 Springs  (forged by a blacksmith)  earlier this year.

Well, the spring arrived and I installed it. It does not work. The sear arm is so short that the trigger pull is very hard and the arm that tensions the block must me too short also. It will hold the block almost closed but the hammer can't fall. I will call Rolling Block Parts today and ask about one although they do not have it listed.
