Looks to me like it's a Ruger 10/22T Laminate Factory stock. Which is a pretty dang nice stock from the get go, but c'mon man, it's a 10/22, if you're building one up, you gotta pour on the glam!

I have a few of those stocks sitting around from my own builds/re-builds. Such a shame having such pretty bits of stockwork just sitting in the back of the closet.

Another option on a barrel, I bought a Blue (like royal blue) Aluminum Tactical Solutions barrel for one of my personal 10/22 builds. I taped it up and painted the flutes a matte silver/grey to match the blue and grey/silver of the rest of the rifle. Also added a DPMS muzzle break made for an AR-15, which I painted matte silver/grey... Just for looks...

I'll work on a pic, but she's blue and grey/silver from top to bottom. Blue Tac Sol barrel with matte silver painted fluting, Boyd's Revolution "Sky" stock, barracuda style in blue and grey laminate, stainless Volquartsen trigger (painted the trigger itself gloss blue), Tactical Solutions Blue aluminum mag release, Nikon Buckmasters 4.5-14x40mm side focus in Silver with 4" silver sunshade, Gloss blue painted flipcaps, silver aluminum Ruger base, Leupold rings painted gloss blue, Matte silver painted Harris Bi-pod, with gloss blue painted knobs, springs, feet, etc. She's blue and grey/silver from top to bottom. (It's an act of love, mostly just fun doing the work... but man she looks good!)

Barrel ran $250, I really just bought it for the looks, but it's been a real shooter.
