Been doing alot of reading up on scoping the M1A. Alot of junk mounts out there. I was leaning toward the A.R.M.S. #18 mount as it has good reports. But then I happened on an M14/M1a site, and these guys over and over recommend the Basset mount for the M1a. I have to say that from the reviews and reports from these shooters, this mount is A+. It was designed by a retired Marine and tested at Fort Hood by the military and found excellent.

I am going to order one. I plan on shooting irons mostly, but this mount is on and off with scope in seconds, and returns to within 1 moa zero or less.

Read the reports from these fellows on the Basset mount. Just enjoy and go down through the threads.

Best scope mount in my opinion is the Sadlak.
Unfortunatly not all M1A Receivers are made in spec and if not the mount will not hold tight no matter who makes it
Sadlak includes a kit to measure the receiver and if not in spec will custum mill the mount to fit prefectly

I've never seen that mount, but it looks pretty sweet and simple. I like the design alot.

I agree with Orlando though, Sadlak makes some serious mounts. I have a Smith Enterprise with weaver mounts and that trough through the middle so I can shoot irons. I love it and have never had issues with it.

There are round steel rails in the mount that self-align and bring the mount back to zero even if the receiver is out of spec. Apparently these steel rails also take the stress of recoil and not the aluminum.

Removing and reinstalling and having the approx. zero is not the issue

The only rifles to have issues with mounting were the Federal Ordinance and Norinco M1A's because the mounting screw hole was drilled off center in the side of the receivers in the above independant test conducted by the University of Houston.

Guess Sadlak must be making up stories then?
I am not saying Sadlak is the only mount out there that works but there are SAI recivers that the groove is not USGI spec and mounts will not hold their zero. Sadlak offers a option to combat the issue.
Ask around on M14 forums and you will find that some SAI receivers have these issues

Not saying any SAI receivers are not up to spec, nor saying Mr. Sadlak is making anything up. Just quoting the findings of the U of Houston in the article that said that the only two brands that the Basset mount would not fit were the Federal/ Norinco because the mount screw holes were too far out of line. Just thought this mount seemed very interesting and could be of interest as to durability and price.

There is a picture of the Basset mount on the M14fl site that shows rounded steel rails in both the horizontal and vertical position machined into the aluminum mount that supposedly self align with the corresponding grooves in the receiver, helping to mate with out of spec demensions.

Here is the link and pics, but it will reguire a sign in to see. Scroll down to post #17.

Just leave it to you all to decide.

Received my Basset mount for the M1A, and it bolts right up as advertised. Have yet to get to shoot because of low temps and snow but I will post as soon as I get to the range.

The rounded steel rails in the mount self align the mount in the grooves on the receiver due to the hole in the mount allowing the assembly to "float" slightly up or down as may be needed until the bolt itself is tightened. Just finger tight and this mount will not budge. At the recommended 22 in. lb. torgue this mount feels like it is welded.

I have the high picatinny mount, and it allows the peep sight to be seen with the mount on.

But the proof will be in the shooting with the weight of a scope and the recoil of a cartridge and the inertia of a moving bolt.

I will post good or bad as soon as I can shoot.

Hickok - I just looked at their website - don't you mean 22 inch pounds of torque?

;)

;)You are so right! I knew better but had a Homer Simpson moment! DUH! Thanks for the heads up, I will amend my post. Sounds like I was torquing down engine parts!

The SAI receivers are famous for being out of spec. In my experience, more are out of spec than are in spec.

The Bassett mount is excellent and works 100% as advertised.

I'd buy the Bassett mount if I had an M1a... Dripping Springs is just down the road. Just drove through it a week ago.
