Six months ago I decided to design and build a custom chassis and make some accuracy improvements on my 1967 Ruger 10-22 that I have had since it was new. I drew it up in 3D CAD and added items as I aquired them. Starting with 6061T6 aluminum billet and bar stock and my old Ruger receiver I made a rear tang mount with a cleaning hole and attached it to the receiver. Then I machined the mounting surfaces and bottom of the receiver flat and parallel to the bore. I added a "0" moa picatinny rail secured with Devcon titainium epoxy and (6) 8-32 flathead cap screws, machined and mounted parallel to the bore. I had previously installed (4) set screws (2 pairs) 45 degrees off center at 10 and 2 o'clock through the barrel bore of the receiver to keep the original barrel from drooping. I decided to use them with the new Ruger hammer forged bull barrel, and added an integrally machined and bored barrel block to clamp two inches of turned barrel one inch ahead of the barrel retaining clamp in the chassis. For easy transport I made it a side folding stock incorporating an adjustable bag rider with rapid and fine adjustments utilizing a Desert Tech SRS monopod assembly in-between two linear ball bearing guide rods. I added flush cups in both sides in the rear ahead of the hinge. For grins, I put an FN M240 butt plate on it with it's shoulder support, that I had on hand. I really like the way it works too when moving between targets! On the other end I built a coaxial bipod mount using Evolution bipod legs and rotating components on a custom designed center section of aluminum on a titainium pivot tube. I threaded the barrel and installed an AAC flash hider / 
suppressor mount on the muzzle. I headspaced and cross pinned the original bolt and firing pin, and installed a Kidd cocking handle, springs, mag release and trigger group. I added 4" picatinny rails with flush cups on the forward sides and bottom of the chassis, and an arca rail under the forearm.
On top is a Vortex Strike Eagle 5-25 x 56 on a Spuhr 13 mil inclined mount with a Knights Armament level under the eye piece. So far it is actually shooting quite well. It seems to like SK Long Range Match and Lapua Center X. Last weekend I shot groups at 100 and 200 yards, the weekend before I shot at 25 and 50 yards. I am happy with how it is going so far, and thought I would share the project with you.
