...This technique is usually used for entertainment...
But, rapid fire with a “slide stock” can be very acuratec.
This public service announcement brought to you by Lake City Armory.
I think that for the cost, I’d rather put in a binary trigger like a Fostech Echo or Franklin BFS. These use the selector lever to produce a standard semi-auto fire in the semi position, then binary fire in the full auto position. But instead of full auto, you get one shot on each pull, then another shot when you release the trigger. So for every pull and release you get two shots, and can effectively get full-auto fire rates with much more control.
I remember the “Good old days” when no one had enough money to waste on shooting. You went to the hardware store, and bought three or four rounds to go hunting with and that was it till next year.
You shot that up in a $10.00 army surplus rifle of some foreign nation picked out of a 55 gallon drum at the same hardware store. Cash and carry.
Only “rich people” had bolt action Winchesters, Remington or Savage rifles.
Accurate too
I stuck a highlighter in a Glock 21 trigger guard and used it as a bump firing stick once. The Glock went full auto sure enough. Then the novelty was over and I never did it again.
My ammo budget is pretty limited so I spend my time trying to shoot groups the size of an apple at 150 yards using only iron sights.
This looks like a “How to get the AR-15 reclassified as an automatic weapon” video. Dumb.
