On the birthday of the 722, I have a story. I just brought home a pretty clean 722, in 222 Rem, rebored to 222 magnum. The bluing is very nice. Wood is B-. Trigger was pretty heavy, so, I took the action off.
Note, a smart man would have taken pictures of the puzzle, I mean rifle, as he disassembled it. There is a magazine spacer. This rifle is right out of WWII. Getting the magazine back attached to the rifle or stock was a real chore. It had me stumped for quite a while. Adjusting the trigger was pretty straight forward. Lots of alcohol and toothpicks to clean out gunk and hardened brown matter. I did not take the trigger off of the receiver. I spent a few hours on the internet and found my issue. I finally found an old thread. on Shooters Forum, it was right on the money. I attached the magazine to the receiver. I THINK I have the spacer installed correctly.
The tolerance was extremely tight. It barely fits attached to the receiver. When I got the rifle put together, I beat on the rifle pretty good with a hard plastic mallet. The bolt never let loose. I will check it more tomorrow. Currently, I do not plan on putting any locktite on the adjustment screws, but I am not closed to the idea.
It gave me some insight into Mike Walker a bit. In older military rifles the wood stock was considered a piece or part of the rifle. I got the receiver and barrel into the stock. It was a little bit high. That is when I used the screwdriver for a mallet to tap the magazine flush with the stock. I hit paydirt when all of a sudden it slipped in flush with the bottom of the wood stock.
I get the idea that the magazine was never meant to separated from the receiver or the wood stock. It was not meant to be messed with, if that makes any sense. I think the magazine is probably the same for 721 and that is why there is spacer. The spacer is a U shaped piece of steel with rounded square corners.
I have two 722s. The spacer is a different design between the two rifles. one is a very early rifle, the other is a bit later. Although the earlier model has been customized a bit, so that could account for the different spacer.
Like a damn jigsaw puzzle. I will be very careful with the trigger. I will beat on it for a few days before I take it to the range to see how it shoots. I put a dab of oil on the bolt and on the receiver rails. The bolt works slick as a gut.
I will update this note when I make sure the rifle is safe to shoot and see if I can hit a barn door at 100 yards. The safety is extremely firm on the rifle. In fact, I would say it is downright stiff. It has a 26 inch barrel. The rust bluing is almost like a 1950s Browning A5. I have an older Weaver scope with some fine cross hairs to try on it.
