Now CT isn't the only place to dislike bayo's. Even the US has rules about new manufactured guns with bayonet lugs. For example I just purchased a Springfield M1A Match rifle and the it has the special Match muzzle flash hider but no bayo lug and yet we can get the Norinco copy with a bayo lug for about 1/3 the price.
Gun rules/laws don't need to make sense.
