Everyone here agrees with responsible firearm ownership. Among gun owners it is my guess that the majority would agree on the current restriction on automatic weapons for example. This is reasonable. It is not reasonable to ban a weapon because of its "look".
A "repeater" AK-47 type weapon can indeed be modified with an appropriate kit. This is highly illegal. It is also highly illegal to buy a fully auto AK-47 as it should be. But if someone wants an automatic weapon they will get one and they will break the law doing so. Banning a "repeating" AK-47 ( functionally just the same as a "repeating" deer rifle ) will not prevent this from happening. It only infringes upon law-abiding citizens and the founders did not intend this right to be infringed upon.
If you are interested, do some research on why Thomas Jefferson valued the second amendment and why it ranks number 2 only behind the right to free speech.
By the way, I do not own a firearm, but I understand the reason behind the amendment and how vital it is that we retain that right and when frivolous gun laws are posited we all need to take note and be concerned.
