No, it does not. The M4 carbine has a three position selector - Safe - Semi - Burst, while the Diemaco C8 and M4A1 also have a three position selector - Safe - Semi - Auto.
Perhaps they just forgot to add the "A1" to the nomenclature in CoD4. But yes, you are correct - the standard M4 carbine has the three round burst feature, while the M4A1 and the Canadian variant of the M4 (the C8) have full auto capability.
.30 Carbine
The M16 rifles have three selector settings. On the M16A1, they are Safe - Full - Auto, and the A1 series rifles are capable of unrestricted full auto fire. On the M16A2, M16A4, and M4, the selector settings are Safe - Full - Burst, and they are limited to three round bursts.
Yes. The M4A1 is a variant of the M4 carbine that replaces the three-round burst mode with fully automatic fire. Both rifles can also fire in semi-automatic mode.
There is a selector switch for the barrel you want. Not both barrels at the same time
yes and no the m16 veitnam was auto the one to day is 3 round burst
Depends mostly 3 round burst though can be fully aoutomatic mos accurate with da 3 round burst
10-round, 15-round and 30-round magazines.
All right, first of all, Hopup does not control the firing mode. That's determined by the selector switch. As the 3 round burst, they do not make guns like that, as the electrical current will have to be cut off to stop the gun from shooting a fourth, fifth round, etc. This is very difficult, because different internal parts, as well as battery size, power, all effect how long it takes the gun to fire 3 rounds. They do make a wiring set that runs between the gun and battery to cut off the electric current for a 3 round burst, but I don't think it's very reliable. Have fun with that.
Yes it does.
M1 Carbine
This answer will be for more than a SKB 500. On any over/under or side by side there will be differences in the mechanism that makes them work. Therefore, place a cartridge in a barrel and in a safe place, pull the trigger. If the cartridge goes off, the feel the barrels and note which is warm. Note where the selector switch is and now you know which barrel is fired when the selector switch is in that position. In the other position, the opposite is true. If when you pull the trigger and the cartridge does not go off, you know that the selector switch is set for the barrel without the round in it. I'd check it with the above method just to make sure. lcj
