I am wanting to put a scope on my Rem 870 SPS-T with Tumbhole shotgun that I use only for turkey hunting. Here is a picture link: http://www.remington.com/products/firearms/shotguns/model_870/model_870_sps-t_camo_thumbhole.asp

Currently it has open sights on it. I am going to take it to a local gunsmith and have it tapped and drilled for a weaver rail so I can mount a scope on it. I have decided againts a b-square and I figured that a rail will be much cheaper than buying a cantilever barrel...that's why I am going with a rail.

I have my scope selection narrowed down to 2 low-powered scopes, but my main quesition is what rings should I buy? What is a good brand that can withstand the abuse of a shotgun blast? Also, how do I know what height rings to get? Will the open-sights that are on the gun right now be in the way of the line-of-sight between the scope and the animal? I noticed that the open sights do sit high, as seen in the pic above. Can those open sights be removed by a gunsmith if they are in the way?

I am just trying to get some helpfull information and any inputs will be greatly appreciated.
