Do paintball and pellet pistols have to be registered?
MCL 28.421 It has been determined that paintball pistols, as they are currently being manufactured, do not propel a dangerous projectile, and therefore are not considered firearms. Although, there is an occasional misconception that pellet pistols only require registration if they are over .177 caliber, that caliber designation only applies to guns made exclusively for propelling BB’s. A pellet pistol, does fall under the definition of a firearm, and is subject to all License to Purchase, Safety Inspection Certificate and Concealed Pistol License requirements.
