KSG price increase due to proposed PUMP-SHOTGUN ban!
Pump-action shotguns, like many law-abiding citizens use for duck hunting and self-protection were not expected to be part of the upcoming Assault Weapon ban proposal. Kel-Tec has been made aware that the KSG is going to be one of the Pump-action shotguns included in the upcoming Congressional Assault Weapon ban bill. The KSG is Kel-Tec’s first pump shotgun and large amounts of resources were put towards its development and production. The distributor price of the KSG has been increased due to this likely ban. If the threat of a ban is removed, the price will come back down to normal levels.
We are sorry for the inconvenience this will certainly cause. Please contact your Federal representatives and tell them you do not support banning ANY pump-action shotguns, or other firearms.
