Gus would be the guy to answer that for sure. If it fits tight and locks up tight i cant foresee any long term affects IMHO.

Hopefully he will check in sometime soon and let us know. I took final measurements. It is approximately 5/16 of an inch on the left side of receiver. So about 5/16 from the the back of the receiver it starts to not touch and goes back to the tip of the heel. The right side is approximately 10.5/16 of an inch from the back of the receiver. 10.5/16 from the back of the receiver it starts to not touch and goes back to the tip of the heel. I illuminated the inside of the receiver from the selector with a bore light so I could see the light coming through from either side and marked appropriately. So the measurements are not going to be off by much if at all.

If only the last 1/2 inch of the heel makes contact on a fiberglass stock, that is enough contact. However, I am at a loss to understand how only the back 1/2" is not contacting unless someone filed down the stock back around the rear of the receiver heel. Bottom line is that on that stock is though it may hold acceptable accuracy now, it is going to wear out and shoot loose faster.

I don't want to beat the hell out of something if things are not working as they should. | It will cause the rifle to shoot loose faster than normal, so yes, I would fix it as soon as possible.

Sounds good Gus. Like I said it looks as though when the stock was received it was sanded a little too much and that is what caused the heel to not contact at the rear.

IOW, there is NO contact until the last 1/2 inch or so of the heel. Anyway, yes, this is enough with a G.I. fiberglass stock.

Gus,
I have an LRB receiver in a GI fiberglass stock. As you can see below, I have a small bit of clearance between stock and the heel of the receiver. There is enough room to slide a thick piece of paper, may be hard to tell from photos. Except at the lower right edge, which makes contact. Is it your suggestion that I have the action bedded to this stock to prevent undue stress?

All the pressure is being applied to the right side. On a fiberglass stock, I doubt that would harm the stock. However, yes, I would fiberglass under the heel of the stock and once again, I would NOT clamp the trigger guard down when doing it. By not clamping the triggerguard down until the epoxy sets up, the heel area will be uniform and will remain just high enough that you should get good heel contact after the epoxy sets up and you tighten the triggerguard in place then.

| 1998 SAI Standard with synth black stock
Not to thread crap here, but this is my SAI 108xxx receiver on the "standard" black SAI (USGI) synthetic stock.
I guess I got lucky, but I also wonder what is going to happen when I try to fit a wooden USGI stock to the rifle.
