Hard to use - TANDEMKROSS Advantage Charging Handle and Picatinny Scope Base, Ruger 10/22

Not very smooth and it's much harder to pull back than than the standard bolt handle. My kids are unable to use it. The handle also sits so high it makes it impossible to use with the cantilever scope mount I am using. That can obviously be fixed with different rings but it's still something that makes less compatible.
Installed easily and looks good, but I removed it after day one.
