Put this on my Ruger Precision Rimfire, and i have huge hands. Best bolt knob ive ever used!!

Advantages: Having large hands it is that much easier using the bolt, the indent rides perfectly on one finger for manipulation.

Disadvantages: As far as i can tell there is no downside that I've discovered thus far. I've sent almost 1800 rounds down range with it installed and i just have nothing bad to say
