    the best size caliper for an ar 15
    .22
    9mm?

    i like the 9mm because ammo is not that expensive and has a little kick/ more than .22

    9mm is a pistol cartridge and as far as I know no one makes a 9mm upper for an AR but it could be out there. Why hump a rifle around if you want to shoot 9mm, get a handgun. Most AR-15 type rifles are chambered for 5.56/.223 caliber ammo although other calibers are becoming popular. As mentioned, .22lr conversion kits or complete rifles are now available for inexpensive plinking and target shooting although .22lr would not be my first choice for HD or SHTF type scenario.

    The 5.56mm/.223 rounds are not very expensive either. Plus, since most are chambered for those, they are more readily available and pricing has some competition. The .22lr conversion kits are easy to find and relatively inexpensive. The 9mm (or any other pistol round) carbines do not have the reach out and touch something ability that the 5.56/.223 rounds have. Jmho. :)

    How big do you want to go?

    There are bolt action uppers available for an AR15 lower that are chambered in .50 BMG.

    There is the .50 Beowolf if you want to stay semi-auto and magazine fed.

    There is the .300 OSSM that may be the meanest round in an AR15 package.

    Then there is always the AR10 family. Starts in .308 (7.62x51 NATO) and I believe can be had in .300 Mag.

    So the question is, what do you want/need it to do?

    Just MHO

    For home defense get you a 12ga shotgun, for fun down at the farm get a .556 AR15 (I have a Bushmaster M4A3) for me I like shooting 1.5" groups at 200 yards or more can't really get that with a 9mm maybe a real good .22. While I'm here I just happen to have a picture of my Bushy & a couple buddy's

    Id stick w/ 5.56 for a versatile, tried and true round that the rifle was designed for. You can buy enexpensive ammo for it or get expensive ammo depending on the task at hand. Sometimes when you deviate from the original platform reliability becomes an issue. In this case 5.56 was the original caliber. Ive heard of people having trouble w/ pistol calibers as well as the larger calibers in the AR platform. Not always but more then 5.56. Theres always exceptions tp every rule. I have a 7.62x39 AR that has worked fine for me but not as well as my 5.56s. If you really want to go w/ a larger round then 5.56 in your AR go w/ 6.8. Its more expensive but the word on the street is manufacturers are gearing up to start producing a better veriety of 6.8 factory loads. Id also suggest a .22 conversion kit to make shooting your AR even less expensive. As for home defense a lot of guys prefer to use 5.56. I know of a couple LEOs that use an AR in 5.56 for HD and others that have the theory of using a pistol for defense until they can get to their AR.

    Colonel, this poster is someone who is also asking for basic caliber information in another subforum. Your answer will be a bit confusing for him, probably. I understand 556. .223 6.5 .22, but those numbers are a little esoteric for his main question.

    I agree: 12-gauge shotgun is the best FIRST firearm for home defense. Then a handgun in 9mm or .45acp. Then an AR-15 in 5.56x45mm (also known as .223 Remington...sort of).

    Until you know more basic information, you should keep handgun calibers like 9mm for handguns. .22lr should be reserved for "plinking" (which just means shooting targets and such for fun) or hunting small game from hunting rifles.

    I really think that 5.56 (.223) will do what you're looking for and be the most common and easiest to get parts and upgrades for.

    Every able bodied, responsible, legal adult in this country should be trained with the basic operation of the AR in 5.56 IMO. All those who can afford one and can legally own one should do so. From that point you add different calibers and barrels, but you should start, keep, and maintain a 5.56 model AR.

    Quoted for TRUTH! .458 SOCOM is really cool and is probably a good 3rd caliber for an AR-15 (.223, then .22, then .458 SOCOM), but .223 is the mainstay.

    And I agree that EVERY American who is least bit inclined should maintain one (as long as they agree with me, that is...).

    Your origenal post:

    what else are there what is the best.

    let me know what you think

    I took it as you asking what we thought was the best caliber for the AR15. I responded that I thought 5.56 was the best round for the AR15 due to greater reliability and larger field of use. Did I missunderstand your intended question?

    And I suggested 5.56 because of its versatility and reliability due to the fact that the AR15 was designed for that round.
