My first response is, Yes, you might absolutely mount a scope on an M1A.
And my recommendation is always the Springfield Armory scope mounts.
Which mount do I prefer?
Its not a quick answer for me, as I have several M1As and each has a specific task.
The steel mount locks into the receiver and once it is attached properly, it is rock solid.
The softer aluminum mount is hammered against the side of the receiver as it is being mounted.
This method works very well too and makes for an extremely solid attachment.
Tools you will need are as follows:
First, ensure that your rifle is unloaded and clear.
Put the rear sight of the M1A in the lowest position.
Let the bolt forward and turn the rifle over.
Remove the trigger assembly, and then separate the barreled action from the stock.
Using the 3/32 punch, drive out the pin from the stripper clip guide from top to bottom.
Next, using your mallet, drive out the stripper clip guide from right to left.
Next, plant the new mount guide in the stripper clip guide groove, and check fitment.
If the fit is too tight, carefully file on the new clip guide.
However, be sure not remove too much material.
Once this is done, tap the new mount guide into the groove.
Then align the pin hole in the clip guide, and tap the new pin into the clip guide.
Next, align the raised guides on the scope mount with the slots on the receiver.
You will now set up the front screw and hand tighten it.
Once hand tightened, you will then tighten it further with your screwdriver.
Here comes the time for the mallet.
Repeat this process until you’ve got the option to no longer tighten the screw.
The aluminum scope mount is now fully fit and seated to this receiver and wont fit any other.
Insert the rear screw and tighten with your screwdriver.
You now may reinstall the barreled action into the stock and lock in the trigger assembly.
Your mount is installed and you are ready to mount your scope and zero the rifle.
Once the mount is installed, there is really never a reason to have to remove it.
I know that is sometimes hard to do, especially if youre a know-it-all like I am.
But you and your impressive shot groups will thank me in the end.
