I emailed Daisy to ask if any thought has been given to 20V solenoid propelled BB guns. With so many tools being operated by L-ion batteries, why not a BB gun? A long-travel solenoid could propel the BBs and adapters could be made to accept Milwaukee or DeWalt etc. batteries. Trigger would be electric, so in other words...great! The solenoid could mount from the rear of the "slide" bayonet style for easy removal and maintenance. A spring-loaded magazine would feed the BBs. The question is velocity, I suppose.
