CASM M1A Mount in Aluminum or Steel?

The one issued to me was steel and so were all the others.

I went with steel. From an engineering standpoint steel is tougher than aluminum - and while aluminum won't rust, it will pit. If you get to dissimilar metals in contact you will get the cathodic reaction thing happening over time.
All that is ivory tower engineering and labs - here in the real world it probably doesn't matter. My M1A is now my primary rifle and I intend to spare no expense with it.

mount goes with steel and rings use aluminum.
Yeah but the gun is steel and if the few extra ounces matters it's time to go rimfire.
I just wanted to add my experiences today. With a Leupold MK4 ER/T, 4.5-14x50 scope with a 30mm tube and steel MK4 rings, the aluminum CASM did fine today. I shot it out to 300 today after working from 50, 100 and 200 since I had removed the scope after my last trip and re-mounted it.
My friend shooting it...
The targets on the left were adjusting the scope to different loads...
My only 300yd target. The high shot was the first shot and I made one scope adjustment to bring the POI down. The second shot was a flyer and the next 8 shots settled in for a very tight group.
I'll try the CASM out to 600yds tomorrow night.

You might consider the Basset scope mount which is aluminum, however it has steel inserts which allow it to be dismounted and remounted without large changes in the point of impact. This scope mount is quite popular in the US with M1A owners and a lot can be found on the web about it. It is possible to order it directly from Basset and is possibly the best scope mount if you do not want to have a permanently mounted scope and want to use iron sights sometimes.

^ Exactly what he said, you can still use the irons with the Bassett!
Now the CASM mount seems to have a lot of success as I yak with folks at the M14 clinics!
What I really like about it aside from the : light weight aluminum, Picatinny rail for a variety of optics is the fact that if you buy a Norc M14 and the sights don't track correctly or are not repeatable, then just scope the rifle with the CASM mount and then your rear sight issue is solved
I've noticed that when you employ a CASM mount, the probability of goofy scope mount issues are less likely, as opposed to the side-of-the-receiver mounts. Many of you guys have learned that cheap mounts are really cheeep and less likely to give you positive results. IF you do get things right with a cheeap mount, then buy a lottery ticket and count your blessings. You got lucky.
That's a good thing to get lucky. Nothing wrong with that. Now if you want a higher likely hood of getting things right so the scope base don't shake, rattle, and roll, then I would put my money on a CASM mount. My only problem is I'm an iron sight shooter with Mr. Jean Garand's creations. Just a personal bias.

Me too. I have a virgin Smith Enterprises mount in a bag that has never seen recoil.
