Mr. Chair, I really appreciate the efforts that some are making to confuse this issue, but the reality is crystal clear. The government, under prohibitions of military-style assault weapons, has not banned 10-gauge shotguns which have a bore capacity of 19.69 millimetres, which is under 20, nor 12-gauge shotguns which have a bore capacity of 18.53 millimetres, which is obviously under 20. The threading of those weapons for the affixation of a choke in no way changes the nature of that firearm. They will not be prohibited.
