Nice gun and was good you got the original two piece bolt back, I recall many years ago some folks sent them in , got the bolts updated , new one installed and they kept the damaged/or broken ( came apart) bolts.......any I ever sent in from our shop, back in the 70s, we held onto the original bolts, same for the real early "unsupported" bolts found in the Red Eagles, if someone wanted to shoot and use them back then......Great little guns and your T-514 is one of the GOOD ones, our favorite......
...and the only way it could get BETTER........
