Bullet button for rimfire?

Hey guys..happy holiday! Bullet button required for Kaiser defense lower with Spikes dedicated .22 upper? Thanks.

No. Rimfire is exempt. You only need a BB if you put a center fire, semi-auto upper on your lower and the weapon has "evil" features.

Dont have a centerfire in the vicinity..(i.e. if youre at the range, dont have your 5.56 upper laying on the bench etc..)dont give them anything to work with.
