No dummy, there, just one here. That Glock sure has the go button, so there is something very odd.
There was an M14 for sale a while back that was a BATFE sting. The "seller" (BATFE) claimed it was legal, etc. When the sucker bit, they shipped the gun. Then they waited a while and got a warrant based on "information", confiscated the gun and arrested the buyer. The gun went back for another round. The buyer went to prison or could have, but most ended up setting for a fine and confiscation of all their guns, which is what BATFE was after to begin with.
