Just picked up my very vintage Benjamin .22 air rifle that they resealed and resoldered the barrel. Before I left the shop, they had to pump it up and shoot it one last time one last time to verify their work.
Nice guys in the middle of Ohio doing good work.
A place to consider if you want to get an old (or newer one) back in action.
Just my 2 pennies
Haven't made it home to try it my self, got waylaid at a gun shop, an antique construction equipment show and a couple of bier garten's.
This old geezer stuff is tough.
