Hey all,
Something I have always wondered about is the cyclic rate, 3 burst modes, and such on full auto rifles and handguns. I'd like to ask some questions and hope to get some information without the suspicion that I am out in my garage with a MAC10 trying to "Home Boy" it up.
Anyway, back to the REAL world. When he Thompson came out I read where the cyclic rate was too high, maybe like 900 to 1000 rounds per minute. It was taken and re tweaked and came out with a lower cyclic rate, Th same adjustments seem to happen with other main battle rifles before they are put into service. Happened with the M16 didn't it? It seems like it isn't that big of a problem to fix a cyclic rate that's too high. So I am curious to know what operations to tweak to get it to an acceptable number? Is it s process involving different spring tensions, or maybe letting less gas escape so the blowback wouldn't be as rapid and thus retard the cyclic rate for the arm.
Next is how the switch on the side is able to fire in single model, burst mode with 3 shots, Burst with 3 rounds and full auto. How does a lever like that able to control the different operating modes? One position you are shooting single shot, flip it to the next place and then you're at 3 round burst and the full auto setting that you can flip it to gives you a pure lead rainfall on your designated enemies. All by the flip of a simple switch.
How does that switch control that drastic difference in operation?
Can anyone explain to me how these things are accomplished in a full auto firearm? I wondered about it for years.
Thanks for your time.
