Well, first off, I have to say I am not sure that Nordic kit is a "drop in" for an average 10/22 action.
It would appear you have to strip the 10/22, the take the factory action and bed it in their lower assembly to be able to accept the stock and fore ends like you would do with an AR Platform.
As for the stock, what is your specific question? The pistol grip has two choices, ERGO ( which is a brand name you can look up ) and black plastic.
The butt stock is either a 4 position or 6 position collapsible, like on tactical M4/AR's
The foreend is being offered as free floated, which is better for accuracy. YHM is Yankee Hill Machine and they make very good products, so if you went that route, and accuracy is your ultimate goal, that would be the direction I would suggest.
Having said that, this a .22lr - it's not like you are building a 500 yard varmint shooter. A bone stock Ruger, with a trigger job and some glass bedding will probably shoot just as well as one of those expensive kit jobs. Were talking 100 yards or so here....
