    Finally got to fire a 6.8 AR

    6.8 Review

    I'm going to wait and see how popular this round is before I buy an upper, but it's definitely and improvement over the M4 5.56.

    My brother-in-law has one, it's not just the ammo that's the pain right now, it's finding the mags which is really silly seeing as how it's only the follower that gets changed IIRC.

    It's got a little more kick, but the buffer system of the AR handles it nicely and in terms of ballistics the 6.8 has more appeal to me that the 5.56.

    Like Jamie Young said, if it takes off I'd probably buy one, unfortunately I have a feeling that it's going to fall by the wayside.

    It's all ready been around for a while, and not gone too far.

    The .17 HMR took off faster than the 6.8 has thus far and there was absolutely no real reason for it (wait, I have a HMR...) and while the 6.8 round itself has advantages over the 5.56, it's still using the same platform. I think that maybe if they had come up with something new design wise for the firearm they may have had more success.



    Only time will tell.

    Either is an improvement over the 5.56. If the Military switches calibers then I will, too.

    I have actually been considering an AR in 6.8 or 6.5 for my wife to start hunting with me. She has picky tastes in rifles that only an AR seems to satisfy.

    Would you folks recommend either caliber for deer or elk?
    I will support gun control when you can guarantee all guns are removed from this planet. That includes military and law enforcement. When you can accomplish that, then I will be the last person to lay down my gun. Then I will carry the weapon that replaces the gun.

    They are at my minimum caliber.

    The 6.8 and 6.5 are not varmint calibers.

    A 6.5 or 6.8 would be a good addition. I would also love to try the 450 Bushmaster when it becomes available. I've also heard good things about the .50 Beowulf. That's one of the great things about the AR platforms, all the options in uppers.

    For most shooting, I like the 5.56, especially since it's so economical. And since I've got a DPMS AP4 in .308, I don't have the pressing need for the larger caliber, but oftentimes, it would be handier just to bring another upper instead of a complete rifle.

    Some info on the 6.5 and 6.8: http://www.m4carbine.net/showthread.php?t=5818

    I don't have any interest in the 6.8 as it is pretty close to the BlackHills 77gr Mk (AKA MK262). The 6.5 on the other hand gives you much better long range capability.

    The nice thing about the 6.8 SPC is the ability to have two uppers for your AR. A 5.56mm or 6.8mm merely by removing two pins and exchanging uppers. 5.56 can be loaded in one set of mags, and the 6.8 in another. A good high speed, fragmenting round for close combat and a good penetrating round for targets behind cover.

    Uppers are available for the 6.5 as well. One of the best AR manufacturers in the country makes them (Sabre Defence).

    Anything that's fast and flat will do, right? There are some 7mm that match that.

    Saw some 20mm cartridges the other day. The pic below shows a comparison between: .223, .338 Lapua, .50 BMG and 20mm. Those sausages look like they could remove the treads from a tank. Fast & flat? Flat enough for varminting, I'd think. A bit expensive, probably.

    I don't know if you'll get the same expansion and fragmentation against a critter with a 6.5 or 6.8. Sure it'll kill the thing, but the ability to quickly transfer energy in small bodied animals tends to be with the fast lighter bullets. I think the 6.8 and .243 may be a little much for most varmints.
