I like the BLM and Joe Biden signs. We have a couple houses in our tiny city with BLM signs [homemade] and a couple others with Biden signs [factory]. I think it is a good thing. Number one, it identifies people I wouldn't have known about otherwise. Number two, 99% of the homes don't have those signs, meaning they disagree, lol.
Other than they're both genuine assault rifles (switchable from semi to full auto) I don't believe there's much in common between the StG-44 and the AK47.
AR stands for "Armalite Rifle". On a side note: Armalite Rifle customer service sucks so bad I will never attempt to do business with them ever again. I still have the item they shipped that the don't carry. WTF!
