I built a custom 10/22 from the receiver up. This is what I have on mine and it was expensive. First i got a Lilja .920 barrel. http://www.riflebarrels.com/
I got my stock from Richards Microfit Gun stocks. http://rifle-stocks.com/
The stock is what took the most time. If you decide to go this way take your time and the results will amaze you. I bedded the barrel on this one because someone told me that the receiver was to week to bed and hold that much weight. Maybe someone will have more info. on this. To this I put a Volquartsen trigger. This trigger is a work of art. Smooth with little trigger creep and very light on the let off. To top it off I put a Weaver type rail on top with a Bushnell Elite 2300 scope. One thing that I almost forgot to say is that the Lilja barrel has a tight chamber. This it very accurate and some 22 ammo will not feed right. I had this problem and sent the barrel back to Lilja which they fixed with no hassle. This little gun will hit 20 ga shotgun hulls at 100 yds. off a bench. Good luck on your gun.
