Most of the people who will tell you how bad Universal M1 Carbines are have never even held one, then there's those who have owned them and maybe shot them informally, then the <1% who have owned and fired them enough to appreciate them and know how well they shoot.
I will start by saying the newer they are, the worse they are. I helped a friend with a late production example and I nearly gave up on it. It was in a cheesy folding stock and didn't shoot
too bad, but shot very low. By doing some serious massaging (bending of the barrel) I finally got it where it would shoot POA at 100 yds. with the sight set on 300 yds.
Not long ago I bought an early (s.n. 30xxx) 1st Generation. It was in a beautiful stock and shot lights out with the sights being regulated perfectly, at least at 100 and 200 yds.
Since falling in the black hole of M1 Carbine collecting about 4 years ago, one of the first M1 Carbine's I bought was a 1st Generation Universal (s.n. 70xxx). Of the more than a dozen M1 Carbine's I've owned, it is THE most accurate and the very last one I would sell. I put mine in a Choate folding stock so I could easily carry it on trips. It will shoot cast bullets right up to 1900 fps, as accurately as jacketed.
Judging from the serial number of yours, it's an early 2nd Generation. I'm betting it will be a good shooter. Someone mentioned the proprietary slides like yours has as breaking, which they can do. Someone is producing runs of these because I've seen new ones on GunBroker and eBay off and on.
So enjoy your Universal and let us know how well it shoots!
