I understand the incremental approach you are describing, however, you have to pick your battles.
Banning bumpstocks didn’t infringe upon my right to keep & bear arms. I don’t own one, and probably will never need to own one.
I will make my stand at the banning of semi-auto firearms, common caliber ammo, and ability to obtain both.
Glock switches and bumpstocks are fun to have, but not the hill to die on, imo.
