No. Two different cartridges.
Ar-15 for one. You can use .223 ammo in 5.56 barrells as well.
$1200Kplus tax. The ammo is going to cost $400/1000 rounds. in 2012
Yes, it can be. It either requires a dedicated .22 upper receiver, or else an adapter which replaces the bolt carrier group.
The AR 15 is a semi automatic firearm- it fires one shot with one pull of the trigger. It can fire as fast as you can pull the trigger. However, that will NOT be accurate, aimed fire.
Depends. What is the caliber of the AR-15 rifle? If it marked 5.56, yes. If it marked .223, no. While you MAY fire 5.56x45 ammo in a .223, they are NOT the identical cartridge, and it is not a good (or safe) practice. .223 ammo can be safely fired in a rifle chambered in 5.56 mm. The 5.56 chamber is cut a bit longer than .223 to help insure operations in the field in the presence of dirt, etc. 5.56 NATO ammo is also loaded to a higher pressure than .223. So- to recap- 5.56 in a .223- NO. .223 in a 5.56- yes.
catching fire is 17 ar points and mockingjay is 15 i think :)
The AR-15 was created by a design team led by Eugene Stoner. Initially, the AR-15 was intended to be a companion rifle to the AR-10; the AR-10 was intended to replace the M1 Garand while the AR-15 was intended to replace the M1, M2, and M3 carbines.
The AR 15 is a rifle, not a caliber. the .223 is a caliber. Usually the AR-15 is made in caliber .223.
The M3 is the semi-automatic version of the Ar-15 (M4).
"Armalite rifle" is a term used to describe two rifles developed for the Armalite Division of the Fairchild Aircraft Company - the AR-15, and the AR-18. The AR-15 was developed from the earlier AR-10. The AR-15 and AR-18 were both designed by Eugene Stoner.
The AR 15 was designed in 1957 by Eugene Stoner. The original manufacturer of the AR 15 was ArmaLite, but they sold the rights to Colt's Manufacturing Company in 1959.
