    What caliber would you like to see become mainstream in the AR-15 platform?

    (I know everyone wants to say 7.62x51 but that fits into the AR-10 platform)

    Excluding 5.56/.223, what caliber would you like to see produced on a more regular basis?

    6.5 Grendel would be my favored round among all the other choices.

    I would like to see more of the 6mmAR. The grendel is a great idea but a bit on the slow side. http://6mmar.com/

    You didn't offer the 6mm-.223, aka 6x45, so I went with the Grendel.
    The 6-.223 offers the least expense in the changeover process for existing guns.

    7.62x51


    It really is a fantastic caliber, and if it were more mainstream it would be cheaper to stockpile and shoot. So my vote will always be for 7.62x51 in a battle rifle.

    Y??? the AR - 15 platform has evolved to what we have today. After 40+ years, 22cal still seems to work well.

    maybe 20-30-40 years from now, we could change again.. or, if you want another caliber, you should just get or have it..

    7.62x54r. Pretty much the only reason I'd own one. But from the research I'd done when first looking to buy one, the 6.8SPC showed the best in comparisons.

    re read the OP. this is for an AR15 not an AR10. So the 243, x51, x54, 22-250, ect are not available.

    6.8SPC

    I'd like to see 3 personally.

    - .45ACP with a high cap mag that will fit in the AR15 magwell. While pistol calibers suck, they are great fun. And the current 9mm conversions are just, well...9mm.
    - Either/Both 6.8SPCII or 6.5Grendel, with a 30 rd. mag to match. You could get much more performance out of these, but then it wouldn't fit in the AR-15 platform (need more length). But currently, ammo is still close to $1/rd. If it became common, we could see the ammo drop. But, I don't like the weakening of the bolt head that 6.5G creates. The previous poster with the 6mmAR has a good thought.

    If they would produce enough to get the price down, 6.8 would be perfect.

    6.8 SPC

    It's a great overall calliber...the .223 it outdated. The 7.62x51 is a beast to lug around to try and carry enough bullets for a sustained firefight. 7.62x39 is OK at best...but the 6.8SPC takes the magazine capacity that the .223 provides and adds some "oomph" to it to reach out and still take down a target at 500 meters+.

    The 6.8SPC is the rifle equivilant to the .40 S&W. The .40 bridges the gap between .45 and 9mm...while the 6.8 bridges the gap between .223 and 7.62.
