So all the whining about semi automatic and “AR-15”s by the left is ridiculous. There is no fundamental difference between the way semi automatic gun operate. The difference is the capability of AR-15 and like weapons is their ability to handle the high pressure bullets generate. These bullets are what cause the horrible damage when used. There is a long history of laws that limit ammunition and magazine capacity being constitutionally acceptable. The reasonable and effective way to reduce the effectiveness of these weapons is to limit the ammunition and magazine. Thoughts???
