I just checked their website and they seem to be on our side. A lot of the gun-grabber groups have started using terms like responsible and violence prevention to mask their objectives. MCRGO's name raised red flags for me but the group is most likely OK.
Thanks for the serious input. Now that I know what this gun is, and it's not an anti-aircraft gun that someone in the Bush campaign office told me, I will oppose adding additional restrictions of the .50 cal BMG rifles to private citizens.
I asked a simple question. I needed a simple answer. I thank those of you who gave me the answer. I would rather make an informed decision then answer a question of which I know nothing about.
