Help on M14 stock ( newbie)

hello and thanks for all the wonderful information provided for new m1a , m14 history. I have a Springfield pre ban era and just swapped stocks out with vintage sacks and son. Problem,
rear receiver is darn near 1/16 of inch high at rear, going to flush around magazine release area . I searched and found some threads but seemingly not this dramatic . Do not want to mess this stock up. Any help much appreciated in advance guys. Serial range 0308xxx

Your serial number has too many digits in it. If you mean 0308xx, then yes, you may have trouble fitting a USGI stock. The receiver has a ledge on the underside of the right rail.

If the metal 'rails' on both sides of the receiver are in good contact with the mating surfaces on the top of the stock, and the trigger guard can be properly locked closed. THEN do a DRYFIRE 'function test' of the hammer being cocked by pulling back the oprod to verify tirgger function.

Having that gap between the rear of the receiver and the top of the stock is certainly not ideal, but it's not uncommon. The only fix that I know of is to build up the rear of the stock with epoxy to mate the U-shape of the heel.

Thank you for the info so far,your correct I was one digit off on serial . Trigger will engage and op rod will function and reset hammer . However the gap is very pronounced. Alternate options to building up rear to close gap.?

When doing the function check, make sure you continue to hold the trigger to the rear after dropping the hammer. Rack the oprod while still holding the trigger rearwards.

The hammer should lock on the rear lugs. When you release the trigger, you will hear a click as the hammer engages on the front lugs.

Better to mill ridge off or relieve wood?
Who to use, (if I want this to look correct ) would be best to send to and can do work correctly and timely ? Thanks guys. I would imagine several 14 armours on this board have successfully done this .

Make sure nothing is binding in the front end, near the ferrel. That gap is not looking good. Does it have a "standard" gas cylinder?

I'd compair to old stock, look for any obvious issues.

Could be a torerence stacking issue and you might have to get another hunk of walnut. Your Sacks and Son looks pretty darn nice.

In picture 3, it looks like the receiver legs are not all the way in the stock liner.Might have to remove the stock liner and file off some metal from the inside front so that the legs of the receiver can go down... there is a post of this in the GUN WORKS OF LA. Where the receiver legs where just a tad to wide.

Thanks from hytekrednek

I'll make a statement with the caveat that others, confirm or deny my thoughts, because I'm by no means an expert. It seems that the stock meeting the receiver above the rear of the mag well is causing the receiver to not set all the way. That's the only contact I see. The receiver is not setting in the liner. I think you have to look at that receiver to stock contact point carefully. It's as if the stock height at that point was set at the dimension of the inside face of the receiver rather than the outside face. This may be the same on the left side also. If that's the case you only have to remove a little wood. You could probably tap the receiver down lightly to see if impressions from the receiver show up on the stock. These impressions will appear as thin lines because to bottom of the receiver has an angle to it- it's lower on the outside than the inside.
Others chime in please.

Thanks from habu1

Serial numbers around 34,000 and below may have this ridge on the right side. It prevents the receiver from being properly seated in many USGI stocks.

Common sense always tells us to modify the cheapest part, which in this case is the stock. There are Smiths on this forum who have modified such receivers so that they can use different stocks.

Hopefully one will chime in and answer your questions.

For those who follow any of my drunken ramblings, this is one reason why I don't collect early M1A's. SAI receivers went thru a series of refinements that didn't fully mature until around 65,000, which was when the factory rear lug appeared on the Super Match.

Early rifles can be great, but you have to understand their limitations.

Even rifles above 65K may have stock fit issues, but those are usually because the receiver legs are wider than usual (probably just a worn cutter). They fit into commercial wood and USGI fiberglass stocks, but they can be a tight fit is USGI wood stock liners. These can be remedied by simply filing open the liner a bit to allow the receiver legs to go all the way down.

I'm maybe a 2mm from the bottom of the liner and the receiver is sitting flush on wood forward of mag release. You can see how high the rear receiver is sitting up. I can't imagine that small gap closure on liner would address the huge gap on the rear receiver.

but, I have been know to be wrong on things I know nothing about.....and this is number one on my current list......my wife would be a close runner up, lol
