Awesome! saved me from a pricier custom build - TANDEMKROSS Advantage Charging Handle and Picatinny Scope Base, Ruger 10/22

I love being able to keep my firing hand in place, I have an aftermarket grip that's easier to control and faster to return to firing. I have a side-charger on another gun so this is great for training/swapping. I could have build a custom left-handed receiver but then it's more money and I'd have to worry about ejection.

Mounts perfectly, can be a little heavier to pull back the bold but still functional/reliable/consistent. Only possible cons I see are 1) raises scope a smidge, but just get lower mount rings; and 2) exposed spring may get dirty, but doesn't connect to existing charging handle so you can still do it the original way.
