america has too many guns in cirulation and a healthy black market, they would have to shut down the gun suppliers first followed by hitting black markets than hitting nation wide strong hold communities all in matter of hours for communism to fan itself alive, trying to remove excess guns as in illegal ownership, would fan the black market. target gun companies and manufactoring would drive up people stock piling and blackmarkets and home made manufactoring.
It would be better to use the gun owners to take over the populace allowing them freedom to excute the masses of free thinkers dissadints, police forces etc...

I have also read this post on another site. There is no way in hell they will try and take our guns....... That would be considered work...... They will just see to it that the ammunition is scarce, and they cost to much for the average, unemployed, beat down, poor son of a bitch that owns them to afford them. Do a little more research then come back and finish your post.
