I did a budget build AR look alike 10/22.
Bought a factory 10" Charger barrel for 80.00 USD, bought a 556 AA stock for 100.00, a 20mm top rail for 12.00 to lock both of the stock parts together, a flash hider for 20.00, flip ups for 30.00, AR rail sight 20.00, sling for 12.00, tri angle front grip for 10.00. Used a spare AR stock I had in my junk box with a higher riser, and a spare red dot with QD rings.
So not into it for big bucks at all, and it shoots great. A gunsmith I know did a 2.5lb trigger job and bolt release mod, other than much louder it shoot the same or better than eith the stock longer barrel.
Was close to the 660mm limit so installed a collar on the slider tube, epoxied and used a pin to make it permanent. I know it's plastic but after 3 years it's holding up just fine and is nice to shoot when cold, just like a 22/45 and Glocks....
Fun to plink with and the idiotic stupid ill considered 10/22 mag limit by the so well respected RCMP has my mags limted,good news is their foolish decision just made me go out and buy another .22 without a mag limit! My gawd they just are so pathetic and Liberal water boys.
