I have a SAI M1A Socom 16 and a question. To those with SAI M1A's, is the spring recess for the bolt lock centered between the two lugs on your receiver or is it off-center? The spring on mine is not straight up and down, it leans to the rear. The recess is a little closer to the front lug. SAI said it was normal, I do not believe them. Can anyone advise if theirs is the same?

All the documents I've seen, indicate the spring hole for the bolt lock, is supposed to be CENTERED BETWEEN THE EARS. And the spring hole is supposed to be straight down.

http://users.nikealaska.org/~sustinemus/M14Receiver_Prints.pdf

The new Fulton I just got is that way - and the spring hole is straight down at a 90 degree plane to the surface of the receiver at the bolt stop.

Now, I'm not talking my Super apart to see - but the photo is of my '97 - with SEI extended bolt stop.

Pretty much - if the spring maintains the stop centered between the bosses, and doesn't "bunch or bind" when the lock is depressed - it should function OK.

Now - is yours 100% CORRECT TO PRINTS?

Probably not.

Is SAI going to replace it (the receiver) under warranty?

Again - probably not, unless your bolt stop is MALFUNCTIONING.

It makes noise as the coils drag against the hole but it functions. I am a perfectionist, I guess I am expecting too much for my hard earned money.

Mine is the same way. Also have what in my opinion is excessive play/slop between the bolt stop and the ears,but it hasn't failed.

Just like the scope mounts on SAI's are truly milspec and no one has ever had issues mouting a scope on their M-1A. Close enough for government work just ain't good enough sometimes....

This is my Springfield M1A Loaded. Based on the drawing that RSConsulting posted, it looks like it should be centered. I think I could have done a better job of centering that hole by hand with my 18v Makita. I think everyone should post pictures of bad craftsmanship on their rifles. That way manufacturers would be on notice to slow down and do it right or the world will see it.

Apparently I need some pointers on how to post pictures. All I see is a place holder but if I click on the place holder it takes me to the picture.
Almost looks like the bolt stop itself is too narrow (or the ears are too far apart). There shouldn't be quite that much "daylight" between the stop and the ears.

That, and the spring should be straight up/down between the hole in the receiver and the hold in the stop.

Weird...

Wanted to bump this thread. This is my Socom 16, looks off center and also has about 1/8" play side to side with the SEI extended bolt release installed. Anyone else's offset like this?

I haven't looked closely at any but my own, upon installation, but that 16 is the wonkiest I've ever seen. Don't know what you can do about that, except mayb e small washers on the rear side to keep the bolt stop more forward, over the hole. As long as it functions, i assume there is no warranty coverage, but you could ask SAI.

My SOCOM has play back & forth , the Spring can be a little off , but it works fine , & I thought about shimming it , just so I knew it was centered , but its has not failed to work & hard to see unless you'r looking for it , so no big deal to me .

Both my early 1994 preban M1As have the spring slightly off center as well, but there is hardly any gap between the stops and ears on either rifle. Operation is smooth on both stops as well...

The offset bolt hold open spring well on Springfield Armory Inc. M1A receivers is pretty much normal.
I do not know why they have not addressed that issue a long time ago; it seems like it would be a easy thing to fix at the manufacturing level.

If you are expecting perfection on a M14 type receiver, do not look for it from SAI.

That's a prime example of tolerance stacking one or all of the parts could be off..... My 238K SAI loaded isn't anywhere as bad looking as some have posted pictures of and my USGI SA heeled rifle is dead knutz perfect..
