It's nothing too special. Here's the specs:
Ruger 10/22 Carbine:
-VQ hammer kit ($34 and brings the pull down to around 3 lbs)
-Sling swivel studs (I drilled for them)
-Uncle Mike's QD 1.25" sling swivels
-M1907 sling
-Tech sights TSR100 sights
I screwed up installing the front sight so I had the gunsmith finish the job for me (and he used some red loctite). The Tech Sights are made in Taiwan and are made out of aluminum. With the TSR100 model, windage is adjustable at the rear only and elevation is adjustable at the front only. The Tool available from Tech Sights is pretty much mandatory for adjusting the sights.
Thanks for looking.
