Picked this one up at the Carlisle, PA show. The seller replaced the trigger with one from a LG53. At least that's what I think that he told me. Regardless, the trigger is wonderful. I noticed that it was a little underpowered, and the other day, she just wouldn't spit a pellet out. Opened it up and to my surprise, found a synthetic piston seal that was in great shape. The spring was nice and straight. the transfer port was clear and the breech seal was good. I just cleaned some really sticky grease out of everything and put it back together. Same issue. Yesterday morning, I opened it up again and removed the mainspring. I found one similar in size. same I.D., slightly heavier wire and about a half inch shorter. The new spring was also equipped with a top-hat. Something that the old spring didn't have. I tried to compress each spring by hand and they seemed pretty close. However, with the new spring installed, she's running right around 6.5 ft/lbs. What a delightful little rifle. Smooth as silk, as accurate as I'll ever be with iron sights, and it's got that classic springer era appeal....
