I recently sold a 39A thru GB to an individual in Maine. Before sending, I took it to the range and did a thorough check-out, running about 20 rounds. The result was as expected, smooth as silk and dead-on accurate. I cleaned the gun and broke it down for a very complete series of pictures, reassembled and checked for proper cycling.... everything was fine. Today I received an e-mail from the guy saying that over the past week he has disassembled and inspected the rifle and determined that it was worn beyond repair... and that when reassembled, the lever action would not even cock the hammer on the gun! Is it possible that he made an error as he put the two sections back together (such as leaving it in a cocked position), or otherwise misaligning the reassembly. If so, what are some common mistakes that he could have made. The rifle functioned flawlessly when sent to him, and my visual inspection indicated no overly worn components (documented with detail pictures). Any ideas guys??
