Picked up an E2 stock not long ago from a forum member here.

Finally got around to placing my Scout receiver and barrel into the stock.

Just admired it for a while then decided it was time to take it out for a shake down.

When I pulled the op rod back, the bolt stopped about half way back.

Took it apart to see if I could find the reason.

Nothing obvious.

Removed from E2 stock and assembled without a stock, worked fine.

Removed from E2 stock and installed in the Scout stock, worked fine.

So it appears something is a-miss in the E2 stock.

Measured the width of the E2 stock liner at .850" and the standard stock at .860.

Any suggestions?

No help?

Well obviously something is binding. Likely issue is the spec of the M1A itself, not the stock which I assume is military. I had a similar thing with mags recently. A mil mag would not run right in my JRA but a CMI mag ran fine. If the bolt itself is being stopped,, is something snagging it or is it the op rod that is being held back? Is perhaps the trigger group really hard to close as if possibly trying to pull the rear of the receiver down so hard that it is flexing it? I am just throwing out ideas here as I have seen similar things before in other rifles. My dad had a bolt rifle bedded once and the bolt was binding for just the reason I mention above. When screwed together the rear tang was being pulled down so hard it was flexing the whole thing. I bedded the tang in line with the rest of it and cured it. Possible something similar is happening here?

Your hammer is probably too high. Try shimming the rear pad of the trigger housing a bit to lower the hammer.

Finally got a chance to try shimming as KurtC suggested.

It took four thin pieces of a playing card under the rear pad to get the bolt to function properly.

Now to take a micrometer to measure the thickness required and then find some brass shim stock.

Thanks KurtC.

Yep, I dredged this one up myself.

The shimming fixed the problem, but I would like to do a real fix to the stock if possible.

Would steaming the trigger area on the stock decompress the wood enough to eliminate the necessity for shims?

Or no way to tell until I try?

After steaming and drying is there anything that would prevent the wood from being compressed again?

It's a USGI E2 stock and I don't want to do anything to it that would devalue it.

KurtC to the rescue again.

Thanks

Use outdoors. No smoking.

And despite advertising, not in the bedroom.

"there anything that would prevent the wood from being compressed again? "
When I store my M1s and M14 types I open the trigger guard and leave it open.

For future reference, the distance from the surface where the receiver heel seats to the surface where the trigger housing seats (see images below), should measure 1.703 - .015 inches.
