    I currently have ARs with .22lr, 5.56, 7.62X39 and 7.62 NATO calibers. What are all the calibers for "off the rack" ARs that can be added to this list?

    .17 HMR
    .204 Ruger
    .222 Remington
    .222 Remington Magnum
    .243 Win
    6.8 SPC
    7mm-08 Remington
    .300 Whisper (.300/221, .300 Fireball)

    300 AAC Blackout
    450 Bushmaster
    450 Beowulf
    300 Remington
    308 Winchester/7.62 Nato

    .260 Rem
    6.5 Creedmoor
    .338 Federal
    .30 Rem AR
    .223 WSSM
    .243 WSSM
    .25 WSSM

    The Beowulf is a .50.

    Never seen a factory AR in .222 Rem or .222 Rem Mag. Haven't seen .17HMR either.

    I'm not sure if it makes the list be cause I'm not sure if the OP was asking, "standard, commercially available" or standard commercially available." If it is the first it maybe it doesn't fit the description of "standard." If it is the latter it is more readily available than some I see listed. It is the 5.7x28. I have my eye on a 6" suppressed one like this.

    6.5 Grendel should be added to the list.
    6mm Hagar is very close. Hornady makes brass and I believe ammo is next.

    Yep forgot about the Grendel/.264 LBC. There's also the 7.62x40WT.
