Now... If you have a whole bunch of other factors as well, you can end up with a condition called "hammer follow". It's a malfunction that will allow more than one shot, but it will also destroy your trigger group in the process as it puts a lot of stress on the sear catch where the selector cam rides. For the record, I've never tried to induce this condition in any of my rifles as they are worth more to me in a fully functional and safe condition.
This is what got that po'bucker in Wisconsin sent up the river last year. He loaned it to a buddy who took it to a range that just happened to have a Feebie at it. Buddy malf'ed the rifle, and the rest is history.
The Feebies have a long and notorious history of fudging their "test" results. Even Randy Weaver's debacle may have started because of Feebie tampering. Randy insists to this day that the shotgun he cut down was cut to 18" legal minimum. What got him was the Length over all by a half-inch. Someone had sawn off part of the stock. Before or after he cut the barrel is unknown.
If you bet on the F-troop lying to make a case, you won't go broke any time soon.
militia bump. I know you were on this.
most any semi-auto can fire full auto if you utilize the bump fire technique. You allow the recoil of the weapon to “bump” the trigger repeatedly inducinga high rate of fire. There’s tons of videos on Youtube show how it is done. It’s bad ass but pointless IMO, real rifleman fire semi-auto.
