Only if they are properly holstered!
A lot of concealed carry only people say exactly the same thing about open carry of handguns. People who claim to be pro-2a.
i get the oc of handguns but why would you want to oc a rifle...lol. I wish it would be acceptable for people to oc rifles and shotguns but people know, it is un-necessary to oc a rifle now a days because of the handgun options. a rifle is a little more intimidating that a holstered handgun. unless...it is at a 2a rally where it would be expected.
