Which alternative AR15 caliber(s)? 6.8 SPC, 300BLK, 9mm, .50

Post by ZombieKraft » Sat Feb 23, 2013 1:32 am

Just like the title says, I'm looking to expand the swiss army knife of the AR15. Right now all I have for the AR is .22LR & 5.56. Putting this in general for those that say "SBR". What route(s) should I go?
  • 9mm
  • 300BLK (I have suppressors :-) )
  • 6.5 Grendel
  • 6.8 SPC
  • 458 Socom
  • .50 Beowulf
just to name a few.....

FYI: I have guns that shoot all popular NATO and Comm Block small arms calibers. 9mm, .40, .45, 5.56, 7.62x32, 7.62x51, 7.62x54R... And I reload.


============================================================================
EDIT: Since some need me to narrow the topic down...


I tend to just put ideas out there and watch where they go. Sometimes I'm pleasantly surprised.

If you must have a scenario.... Your safe house is in the country. You are going into the city to grab supplies (open country exposure but you have a vehicle). 1 hour drive to the city... at least. Then a day of foraging in the concrete village (travel light and fast... no car).

This scenario was seen in Walking Dead. Season 1.

Now you have a scenario that is quite common. But im all ears for alternative insights.

What is the easiest to reload with materials you already have?

Be useful in the ZPAW, EOTWAWKI, etc....

300BLK is great for running suppressed.

6.8 is short/medium rang.

6.5 is medium/long range

458 Socom and 50 Beowulf are the big boys.

Or you could just list all the alternative cartridges for the AR. Oh, wait.

Can we get some pics of your current set ups?

I'd go .300BLK, as it uses standard 5.56 mags, just need new upper.

FWIW, that’s my choice too. Love the 6.8 (no experience w/the 6.5) but if I’m looking to shoot longish-to-long range I’m reaching for a .308 anyway.

I think one of the .458 or .50 uppers would be a hoot but not sure what they'd do for me that a 300BLK wouldn't do (at close-in range anyway). Bigger hole, sure, but a lot more noise and a lot more buck ($$) for the bang.

Why not go with 7.62x39 and reload that for subsonic?

At worst you might have to switch out the main spring when putting the 7.62x39 upper on to keep it cycling subsonic ammo. But maybe not if you up the bullet weight to over 180gn.

That way you can run another common ammo and if you run a silencer you might be able to use it on a .308 gun also if you have one.


I wonder if they have mags for that AR variation?

Subsonic 7.62 will not cycle the action of the AK or the AR. It was tried and it just doesn't cycle very well at all. So far, only the 300 BO does both reliabily.

ACC tried it. Russians tried it. ACC scraped the plan and developed the 300 BO. The Russians scraped it and developed the 9x39mm and an entirely new weapon system for it. True story.

Sorry I also forgot about AK ammo is tapered so good working mags for the round in an AR lower is unworkable.

Yea .330 BO would be the way to go if all you really want is suppressor fun.

.458 SOCOM also can use the 5.56 mags. 30 round 5.56 becomes a single stack 10 round .458 SOCOM.

I'm still tossing between the .458 SOCOM and 300 Blackout. Luckily I have plenty of expertise in my chapter and they like to keep me confused. :clap:

Id love to run a socom or beowulf upper. But I just dont have a practical need for it that justifies the cost. That said I really want a CMMG .22 bolt carrier.

How long is your barrel? For a shorter barrel Im partial to the 6.8 SPC. But, suppressors are also fun...

9mm if you're concerned with cross compatability and availability, and less about ballistics.

300blk if you're concerned with suppressed performance, want a short SBR, and have the hardware to support.

6.5/6.8 if you specifically want to hunt with it.

.458/.500 If you're wanting to hunt larger game, or just have self security issues. :rofl:


I personally went with 300blk for the reasons above. We don't have game large enough in Florida that I'd need anything larger than a 75gr .223 anyway.
