I am the new owner of what I believe to be an early 80’s 110E, it has a very tight bolt, the sliding back and forth action is buttery smooth, but, the cocking action is very tough. I believe it may be the cocking piece that is inside the bolt, but it looks as though the part is no longer in production, and I cannot find one online at all! Has anyone had any luck locating this part? The one in my gun is scared and looks to be very warn, may also be out of round causing he issue. Thanks in advance!!
