I just recently struck a deal for a SA M1a Loaded Rifle, Model MA9826.
I'm looking for information, from learned persons, on what the best Scope Mount and Brand of 20 or 30 Round Magazines they would recommend.:confused:
Thanks in advance for sharing your knowledge,
Mike - SW Florida

The 3rd Gen mount that SA has for the M1a isn't bad for light duty. If you plan to use the rifle with scope for serious work you'll want to look for a different mount. Fulton Armory (http://www.fulton-armory.com/) isn't a bad place to start looking. Sadlak (http://sadlak.com/si_rifle_parts_sm.html) also has a serious mount. As for mags stick with USGI. The FA site has details about those also.

The Sadlak mount is the way to go.Sadlak makes an improved version of the now defunct Brookfield Precision mount,its THE way to go on a M-14/M1a.The mount is expensive but well worth it.Yes,stick with 20 round USGI.

I have this on gunbroker.
The mount works good if you throw a bit of loc-tite on the threads before tighening it down. I have two M1a. ONe I am keeping iron, and the other has an aimpoint w/ the 3rd gen mount. I have never had a problem with the mounts, but then again, I am shooting at paper and varmints...not dodging bullets and hunting insurgents. I would let this go for $300+shipping.

Welcome to THR!
Avoid the 30 round magazines. None of them are milspec and it would be difficult to sort the garbage from the gold.
Plenty of 20 round magazines are out there and it's difficult to sort those as well since they get counterfit markings all the time. That said, look for small even spot welds and good finish and almost all of them are good these days. The best are old military mags or the new magazines made by Checkmate industries. They make the magazines for Armalite and Armalite sells the M14 magazines for $25. Wideners (http://wideners.com/itemdetail.cfm?item_id=6721&dir=625|629) has blued aftermarkets that the folks at m14firinglineforum.com like them pretty well. Wideners sells them for $15 each.
Look here (http://www.m14firinglineforum.com/upload/forumdisplay.php?f=65) for more mag information.
My scope mount is from Mcann Industries. http://www.mccann.shop-utopia.com/mount/m1a_m14mount/m1a_m14mount.html

The biggest downside to the SA 3G mount is it's not the same metal as the receiver. In a short shot string or even a long day of shooting with lots of time between shots it's not a problem. In a longer or rapid fire strings of fire the rate the metals expand with the heat makes your zero go out the window. Two 20rd mags were enough to cause a problem for me in 3 gun shoots. I learned to do my longer shots first to reduce the heat effect. Even at closer ranges my zero moved by up to 4 inches.
The biggest question is how will you be using the rifle? Slow fire, short shot strings? The SA 3G mount will work fine with a little loc-tite. Faster strings or a demand for less zero drift? You need to look elsewhere.
A side note to go along with the mount, expect to use GOOD glass on a M1a. A scope that might be fine on a bolt gun will be beat to pieces by a M1a. They have a well earned rep for breaking glass.

I have a 3rd Gen mount and never got it to hold worth a darned.
