One round in the chamber, and (normally) 20 or 30 rounds in the magazine. However, there are magazines that hold 5, 10, 40, 45, 90, and 100 rounds of ammunition, each with varying degrees of reliability. It also depends on what round that particular AR-15 is chambered for.
Between 600 and 900 rounds per minute, depending on how "hot" the load is and the mass of the gun's buffer. The AR-15 has a greater tendency to jam at rates above about 800 rounds per minute.
No. The two rounds are not interchangeable.
No, but it could be made to by changing out the follower.
$1200Kplus tax. The ammo is going to cost $400/1000 rounds. in 2012
catching fire is 17 ar points and mockingjay is 15 i think :)

The answer below is false, the AR-15 has no "automatic fire mode", the M-16 (to which the AR-15 looks like) has a rate of about 800 rpm (however that's more of a representation of how fast you can empty a magazine in relation to 1 minute, it would be impossible to successfully fire this many rounds while managing to reload every 3 seconds 20 times in said minute) and also has no "automatic fire mode," it has a 3 round burst. The AR-15 (if you're actually aiming at anything) is close to about 60 rpm, similar to the average hunting rifle.The AR-15 rifle has a cyclic fire rate of 800 rounds per minute. However, this is only in fully automatic fire mode. When firing on semi-automatic, the shooter can expect to put 45-60 rounds downrange in a minute depending on how fast he/she can pull the trigger.
The AR-15 rifle has a fire rate of 800 rounds per minuteand a muzzle velocity of 3,200 feet per second.
Without modification, no. The two cartridges are not compatible or interchangeable in any way. If you have a 5.56 rifle, such as an AR-15, it is possible to build or buy a 5.45x39 upper for it... you'd still use the regular AR-15 magazines, but a 5.45 follower would have to be used.
The Colt AR-15 SP1 is primarily designed for .223 Remington cartridges. While it can safely chamber and fire some 5.56 NATO rounds, it is not recommended due to potential differences in chamber dimensions and pressure levels. Using 5.56 NATO in an AR-15 SP1 may lead to increased wear or safety issues, so it's best to stick with .223 Remington ammunition to ensure safe operation. Always consult the manufacturer's guidelines for specific recommendations.
There have been several. AR style pistols use the same 20 and 30 round magazine as the AR 15. One version of the "Broomhandle" Mauser had a 20 round magazine. Several modern day auto pistols have extended magazines. The Keltec PMR-30 holds 30 rounds.
