Colt AR15 and the 3 round burst.
« on: January 31, 2015, 03:54:42 PM »
       Just out of curiosity. This issue was brought up some time back but I hadn't the time to comment on it.

       For those who feel that the Colt AR15 and like type semi automatic rifle are in your opinion an assault rifle, would you care to share with us the meaning of the three round burst and why it's been adopted as a combat firing technique. Also, describe what the three round burst is and do you feel the Colt AR15 and other like type semi-automatic rifle have such capability. In the sense of modern combat please share with us your opinion of what an assault is. How many here who feel that an AR15 and other like type semi automatic rifle are an assault rifle, have you ever used an M16 or other fully automatic/mechanized weapon and or been involved in a close proximity multi combatant firefight?

It was to save ammunition. It was found after Vietnam that rounds per hit was atrocious. It was to improve marksmanship and conserve ammunition. No such thing as an "assault rifle". Made up term for the present day libs but originally I think it came from the Germans.

And yes on the last part. 4 combat deployments.

No such thing as an "assault rifle".

There is most definitely such a thing as an assault rifle.  That is a legitimate term, used by both military and BATFE, to describe a medium-caliber rifle capable of selective fire.

The made-up term you were looking for is "assault weapon."

If I am understanding the OP correctly and the point you are trying to make is that the Colt AR-15 and other similar semi-auto rifles are NOT "assault rifles", then I think most on this site already agree with you. At least I do not consider a Colt AR-15 an assault rifle and no I have never handled a M-16.

The 3 round burst operates of the selector switch as a cam. The auto sear will click the cam every time the bolt is recoil past the disconnector ,.
The cam has  teeth and a final tooth (large) will hold the sear and allow the disconnect work.
 Sounds complicated but is actually a very simple design when you examine it up close.

In my opinion controllability is the main factor , although others my differ.
A full mag will be gone is a few seconds and the climb of the bore is ridiculous. The 3 rd will allow the shooter to keep the sights on target and fire several rounds in the vicinity of the target.  At full auto I had only 2 rounds on paper out of 30rd @ 25 yards. keeping a burst of 3 I had reasonable control of the gun.

Notice in the Vid when I was firing 3rds burst with control,  and at the end of the vid the muzzle climb was uncontrolable at full auto.
Even the MPS with 9mm is uncontrollable at full auto,
However, with an open bolt its impossible to shoot semi auto.!!!!!!!

One more vote for the M-16 being very difficult to shoot full auto.

Shooting full auto is done much better by guys with lots of experience but still the M-16 is optimized for semiauto fire. Machine guns like the SAW are very easy to shoot "accurately" in full auto. I was qualified on the FN MK46 witch is a version of the Squad automatic weapon belt fed 556. It is heavy and is nice to shoot 8-10 round bursts. I was NAVY with no combat experience.
