It's pretty close but I get more fliers when I'm shooting the .22, I dont change settings. But my barrel is chambered for 5.56 with a 1/8 twist. I think to fire .22 more reliably you are recommended a 1/12 twist, but dont quote me on that because I'm going off memory here. If you dont care about SS and just want a phospate one you can find them for around $140-$150 all the time.
I'm probably going to buy the parts to assemble a dedicated .22, I'd be looking around $300 in parts for a cheap plinking upper.
