Hey guys, I did a search, but still have some questions unanswered...please help. (I think the Model 10 is 110 based, right?)

I'll be ordering a Mod 10 Precision Carbine in .223 soon. Some things I'll need immediately are an EGW scope mount. At Midway, they're listed as 'round rear section' or 'flat rear section.' Which one is this rifle?

Later, I'll be considering higher capacity mags. I saw at SSS they have some, but I am unclear as to whether their system will support .223, and if so, what exactly to buy.

Thx for the help, I'm a newb to Savage firearms......but so far, I do lover their stuff!
