Not for ar22...unless you have a dremel - Wolfpack Armory Armory Gas Blaster Charging Handle

I got this for my AR22 build but it kept jamming when trying to rack it. At first I thought it was too tall but after comparing it to my other charging handle, I realized it was where it grabs onto the bolt. Instead of being 90⁰, it was more like a 45⁰ for extra reinforcement and as such it sits around the top of the bolt instead of just in front. But 22lr bolts are wider than others so it was pushing itself into the top of the receiver and causing a ton of friction. So I took a Dremel cutoff wheel to it and rounded it out. Just like that, no more jamming it's smooth as butter
