Mine are single fire.
And I have AR15 also.
No need to choose. I watch both Star Trek and Star Wars and laugh at the debaters. (For the record, Babylon 5 and Firefly are both better than both)
Do you also own a Ford and a Chevy?
Yeah, the debates on these issues are kind of stupid. Different machines, movies, etc. for different purposes. WRT the AK vs. AR debate, both do exactly what they were designed to do - and quite well.
The AK is designed to be an ultra-reliable rifle shooting a medium-sized .30 cal. rifle round. Accuracy was never deemed to be its strength, because the Soviets’ doctrine of the time was oriented toward massed fire by incredibly numerous troops. Its tanks and artillery of the time reflect the same doctrine.
The AR was, OTOH, designed to fire a heavy .22 cal. bullet (heavy for the time - obviously we now have 77 grain bullets vs. the original 55 grain FMJ) at a high velocity and accurately (for a regular issue combat rifle), so as to produce wounded enemy soldiers (wounded soldiers, so went the theory, need 4 people to haul them off and more to fix/heal them, while a dead soldier needs only 2, and only temporarily). The AR has improved steadily over time, whereas the AK is still the basic rifle that it was when designed.
Lots of people that I know have both, and either will send bad guys running the other way when you point it at them. If they don’t run away, either will kill them, or at least take a lot of the fight out of them.
P.S. Trek is better than Star Wars, and Chevy better than Ford. :>)
