A couple of stock questions

I recently bought some stocks from Fred's and am very happy with them. They are cleaning up very nice. Have a couple of questions though.

Is it possible to remove the forward sling swivel without drilling it? It looks to me to be riveted. And if so, how would I replace it? I'd like to get all the hardware off before refinishing.



And the metal liner inside the stock looks like it needs a very small spanner wrench to remove it. Is there a special tool to do that, or should I just leave it in and work around it?

Question 3, the metal bands on the fore end and hand guard, how do I take those off, and put them back on?

Sure would appreciate any advice on this, thanks!
