2 round bursts possible?

Just out of curiosity, which models in the m16/ar15 family offer 2 or 4+ round bursts? Are they actual production rifles, or just experimental models?

The rifle I have actually seen with a 5 position selector was modified by a police armory. So it would be experimental then, I suppose.

An AR-15 rifle is NOT a full auto or even a burst fire weapon. It is a semi-auto only rifle. There are, however, AR-15 recievers which have been converted (both legally and illegally) to fire fully-automatically. The AR-15 was built as a title 1 semiautomatic rifle and then converted into a class 3 full auto rifle. The method of modifying an AR-15 to fire full-auto is not the same as a M-16.

Also, it has been impossible to legally do this conversion to an AR-15 since 1986.

An M-16 reciever is milled differently in order to recieve the more complex fire control group. The M-16 has a milled space for the GI auto sear, and a little shelf for the return spring on the auto sear to fit. The M-16 has a different hammer (with a J-hook to interact with the auto-sear) and also has a different bolt carrier.

So a full auto AR-15 can have any configuration of fire control the Modder wanted. Some AR_15 full auto mods are so-called "drop in" mods because there is a bent piece of metal inserted in the weapon which renders it full auto only when off safety. Other modifications are less crude and make the weapon function just like a military rifle (just that it's .223 and not .556mm).

The selector switch literally looks like a miniature crankshaft from a car engine but with flats milled into it. The position and configuration of those flats are what engage the different fire control modes.

I actually didn't read any information before I posted earlier. I just wrote all this off the top of my head from experience. I have manufactured firearms in the past from raw materials. I have also assisted and advised others in the manufactire of rifles and pistols from raw materials. This includes scratch built AK-47s, M-16s and M-1911A1s as well as experimental weapons which have no nomenclature.

So, just to pop in some non-original data, here is a excerpt from wikipedia:

Most M16 and M4-style weapons issued are capable of semi-automatic fire and 3-round burst. The burst-fire mechanism utilizes a three-part automatic sear that fires up to three rounds for each pull of the trigger. It is non-resetting, meaning that if the user fires a two-round burst and releases the trigger, he will encounter a single round fired the next burst.

I dunno what game engine you are referring to, but not in BF2. There are 3 rates of fire:
0 = single shot
1 = 3rd burst
2 = full auto

There is no "mosability" to the fire modes.

Really, it'd be pointless to have control over the fire modes anyway. 2rd and other bursts are as rare as dodo birds, especially in the BF2 setting. Maybe if we make a meth-lab faction with illegally converted weapons there'd be all that stuff.

One thing that the game lacks, but I am afraid is not doable because of hardcoding and all that is the "flaw" in the ratchet design of the M-16. The ratchet is non-resetable. Each time you fire the rifle on semi-auto the ratchet on the auto sear will advance one position. The result would be like this:

Bang...
Bang...
*switch to 3rd burst*
bang...
BangBangBang

Even though the selector is in the burst fire mode, the ratchet isn't. If it has one or two rounds left before resetting, it won't fire a full 3 rounds until the second trigger pull.

exactly. i dont know why it is so hard to explain that it works this way because for some reason some people seem to want to deny it.
