Arms Unlimited announced they will be releasing actual M203 grenade launchers to the civillian market for sale. Since these are 37mm and NOT 40mm no NFA rules apply to this product. This is Title I non-restricted, so you can just throw this on any of your Ar-15’s especially if you are wanting to do a clone. 9 inch and 12 inch models will be available for sale in limited quantities.
