Tackleberry
I have a Norino model 56 built in 1980. (I know this because I was able to track the serial number). All the numbers match on this piece and someone has taken care of it. I bought it used, complete with a number of mags, bayonet, and I believe, a trigger overhaul for around $250. The trigger wasn't modified, however, but just cleaned up so it works as intended: no grittyness: nice and smooth but long.
As for the sights, I put a set of Williams WSKS aperature sights on it (around $20) and was able to set to zero in short order. There are two screws on it. One for elevation and one for left/right. So, you can easily compensate.
As for the action not locking open, that is the result of a piece missing on the clip. On the back of the follower, there should be a small bump about 1/8" diameter and high. Like the head of a small screw. When the last round is fired, this small bump forces a small spring loaded metal tab, found in the receiver, up to hold the action open. I have two 10 round clips which did the same thing. I modified them with a little work so they do hold the action open. However, I've abandoned the other clips that came with this rifle in favor of the fixed magazine for two reasons. First, I can load 10 round with stripper clips as fast as you can change a the detachable mags and second, I hold my rifle in a shooting stance which requires that I palm the bottom of the fixed magazine area. After-market mags are too long or sharp. So, consider going back to the original magazine and buy some stripper clips. As for the length I agree that the original stock is too short and the "soft rubber" butt extension is too long. I, too, cut it on my bandsaw so that it is about 1 1/4" long which is perfect for my arm length. I don't want to change stocks and would prefer to keep the original wood although I refinished it (I'm a cabinetmaker). If you need more info about altering the clips, let me know. I can email you photos of my clips modified clips if you like.
One more thing. I read many places about the barrel getting hot after rapid fire. Every single rifle at the range had the same experience. I don't know why this becomes such an issue. Even after five round in three minutes, the barrel was pretty warm. After 1 1/2 hours, the barrel was down right hot. Big deal, so was the M1, AK47, and the Bushmaster. As long as it isn't glowing cherry red, I figure I'm ok.
