I've recently started shooting Steel Challenge, and built a 10/22 ....design criteria was to use the reliable factory Ruger 10 round rotary magazines, and have a similar feel to the rest of my AR competition carbines...... in case I used something that might be of interest to you

receiver is Brownells BRN22 with integral rail (had a rail loosen on an earlier Ruger used for the Chevy Truck Sportsman's Team Challenge)

barrel is also Brownells companion barrel for the BRN22 receiver... threaded... I polished the feed ramp, and took a slight bevel cut off the mouth of the chamber with a reamer... if at some later time I can switch to a light weight carbon fiber.. with my shooting ability, this will most likely not happen

bolt and charging handle factory Ruger

trigger group Ruger BX...in the mid 90s there was not a lot of aftermarket competition support for the 10/22 ... I built a fixture that changes the angle and depth of the sear notch on a factory Ruger hammer, and with a couple of other spring mods, got a reliable 22oz trigger... that is not necessary for the Steel Challenge

chassis PMACA lightweight with a cantilever rail off the nose to mount an angled fore grip

stock is ArmaLite SOCOM angled cheek piece stock,

grip is a Hogue over molded

sight is a Holosun 510

Honestly the most cost effective way ( unless you go all premium aftermarket parts like kidd or volquartsen-$$$) is to buy the cheapest off the rack Ruger you can find.
Unlike AR’s where you could find parts kits for less than complete rifles for builds ( not sure about now with the current frenzy)
No such resource exists for the 10/22
If you can find a mass merchandiser that puts a 10/22 on sale for $199, or find a good condition used one for $175 or less, you simply cannot buy all the parts needed for less.

SAP Outfitters sells OEM Ruger parts; some takeoff, some new.  Their prices are eminently reasonable.

This past summer when I did my first printed 10/22 I just made a post here asking for take off parts.  Quite a few members came forward with parts.  




It's a shame you want a 10/22 I know a guy who does Marlin's.

It seems that 10/22 parts are still hard to find.  If you have the barrel and receiver, it isn't difficult to piece it together.  Signup for alerts like Midwayusa and Brownells etc. for out of stock items.
