1903A3 Sporter Questions

How can I check this?

The barrel should be stamped if it has been rechambered. If it is an 30-06AI, it will still fire standard 30-06 rounds, the cases will be fired formed to the AI dimensions when you extract them. The only way to know for sure is to make a chamber cast with Cerrosafe. It's easy to do and will answer the question of what cartridge the rifle is chambered for.

cant tell is that a stamped or milled trigger guard?

I think the guard is a stamped guard. It does not appear to have any milling done to it. Is there any place in particular I should look to be able if it is milled? Also, I did notice that there was some welding or soldering done to the guard right by the mounting holes. I'll take some pictures when I get home this afternoon. The trigger itself looks like it was changed, as it is grooved.

On the inside of the stock where the magizine is, there are grooves in the wood from the box. One thing I think might be happening is that the stock is squeezing the magizine at the top, which it turn pushes the follower toward the non-ejection side at the top of the mag which could cause the final round to roll a bit to the non-ejection side causing it top pop out.

thats what i would guess,
try the rifle out of the stock, and see if it cures the problem.

OK, I took a ton of pictures of the stock, trigger guard, trigger, grigger guard bolted to the reciever with and with out the stock. I also ran the live ammo through the rifle (no firing pin) without out the stock, and 5 rounds fed and ejected perfectly. I do however have a new theory which I'll explain in a minute. First here are the pictures of the stock where the mag fits from the under side and of the trigger guard, which is a stamped peice.







Trigger guard. Notice in the second picture, the weld or solder by the bolt holes.









Trigger. I don't think this is an orgional trigger:



Here is the rifle back in the stock. Notice the gap between the the bottom of the trigger and the trigger guard:



Now, here is the rifle bolted together with out the stock. In the second picture, note how the mag comes incontact with the reciever.





Here is the rifle, with no stock, where I have unscrewed the screws so that the gap between the bottom of the trigger and the guard is about the same as when the rilfe is together with the stock. Look at the gap that is between the mag and the reciever. I ran rounds through the rifle like this, and, like when the stock is on, the final round ejects with the second to last round. So I think that the issue is that the mag and the reciever are not mating up at all, causing the follower to stick and the last round to pop out.





Thoughts?

well, i see a few issues. fisrt is the after market trigger, it can give you fits, and im suprised it works with the stiker assembly without fitting, and is the reason your safety doesnt work,
second, the trigger guard looks like its been modified at the top, id find another.
third, the stock needs to be fitted alot better, the trigger guard doesnt seat into the reciever well enough, that in itself is your issue with it popping out.
i would say the stock need to be fitted by a gunsmith that knows how to fit a rifle.
