DEALS US Color Anodized Aluminum Extended Lever for Ruger 10/22 (Silver)

There are quite a few places selling very similar looking mag releases. I don't know how many actual mfgs there are, but this one had quite a bit of slop in the lateral movement. I ended up placing a thin (~0.4mm) nylon washer on the pin between the right side (from firing position) and the mag release lever to remove the play. After that it operates well enough, but if this was more precisely milled, it wouldn't be necessary.

Not too bad to install since I was working on the trigger anyway, makes releasing the magazine much easier

Well shaped but not precision drilling very loos and flops under trigger guard
