Ah so that's why people are into the blk. You can use a standard lower and the same mags. Hmm gonna have to think on this some more.

Nope. It is a larger lower. And the lower really doesn't see much of the stress in an AR.

Also keep in mind that Stoner's original rifle submission was the AR 10. The AR 15 was a down sized version.

Thanks. With all the new cartridges I get fuzzy on some details. I did think that was one of the benefits of the cartridge though.

300 is not a version of the 308 Winchester, and AR10 rifles are huge and heavy compared to 300 BLK rifles.

Yes there is - the most popular rifle of all, the AR15.

The 300 blk uses all AR parts except for the barrel. Using a trimmed .223 cartridge you can make your own cases. Uses standard and readily available bullets made for the .308 platform. Uses standard AR mags and all that out to 300 meters no problem.
The 300 blk does what all the predecessors have been trying to do Make a round that cycles and performs well using a many standard AR parts as possible. The only thing you HAVE to change is the barrel all other parts interchange and THAT is why it is becoming so popular. In states where you are not allowed to hunt with .22 cal the 300 black gives you the ability to take big game with your AR.
The only downside to this round is the long distance shot is much more difficult our just not worth the math for most shooters. Not a bad trade off in my opinion.

"300 blk vs 7.62x39
Which is better and why?"


Personal preference.

I don't have any use for the AKs or their ammo. This doesn't mean that it is bad/no good/(insert your own adjective).

Standard/normal weapons:
AKs are loose. Run dirty and just keep on going.
ARs are tight. Some run dirty, most like to be clean and well oiled.
AKs have 'crap' ammo. It is cheap and plentiful. Not great accuracy, can do better (some say much better) with good stuff.
ARs have good and consistent ammo. Quite accurate for most.
AKs, military surplus is 139 or so grain FMC. Not the best bet for hunting.
ARs, military surplus is 55/62 grain FMC/steel core. Not the best bet for hunting.

But we are talking about the 300 AAC Blackout.
An AR built for the Blackout is tight and accurate. Great ammo with bullet weights and types for all needs from 110gr to 220gr and more.
No, it is not fair to compare great loaded stuff for the 300 BlackOut to crap stuff for the AK.

The AR in 300 AAC Blackout is the standard AR15/M16/M4 configuration with a carbine gas system and buffer. Same everything except barrel and tend to favor shorter barrels at that.

But which is better? Personnel preference. If all you want to do is bang away, go with the AK. The 300 BlackOut is more expensive, but then they are no more expensive than any comparable AR in .2233/5.56. Factory ammo (I have never shot any) looks to be reasonably prices. I cut down dead .223/5.56 brass, form it and trim it, same primers and have my selection of bullets. Oh, it uses less powder than it's little daddy round.

So, pick your weapon. I've picked mine..... But I still have and like my other ARs.

it uses .308 bullets in a necked up .223 case. my scar17 weighs in at 7.9 pounds hardly a heavy weight.
