I never said Bump stocks made a weapon automatic. They don’t. I said that pretty much they are a novelty that aren’t very accurate. In a live fire situation they aren’t t much good.
If you have that much experience with automatic weapons lay down on the ground and fire a bump stock then get back to me.
Note the last sentence of the 4th paragraph of my reply. The word “prone” means “lying down.” I did exactly that, with a bi-pod, and the accuracy performance with the bump stock in bump fire mode at 100 yards was 100% hits with all bursts on a man sized silhouette target.
Again, this was after one afternoon of practice. Maybe my experience enabled this performance, but I think that any person of normal dexterity and marksmanship ability could obtain similar results.
