6.8 SPC or 300 Blackout

[Member 34319]

I am thinking about buying a second AR rifle and I want something with a little more punch than my current 5.56. I was looking for some advice as I have not owned/fired an AR in 300 Blackout or 6.8 SPC. It will be a target, self defense rifle. I don't plan on running suppressed. Which is the better caliber? Pros/Cons of each caliber?

For brand I'm looking at LWRC, DD or POF. I have an LWRC now and love it, but have owned the other brands and liked them also. Any advice/experience on the calibers will be greatly appreciated!

If your on a LWRC high, stick with it and get their Six8.



300 black is a suppressed caliber. Yes some run it solely super, but it's meant for quiet operation hence the name designation "blackout".

On the other hand, with a 9" barrel .300 blk shines even with supers. It isn't JUST for suppressors, its about having similar ballistics to 7.62x39 in an AR that can still change parts with other ARs, while also being short. In addition to having subs for suppressors.

That's why you just go with 7.62x39 in AR. Honestly how many parts do most of us swap around? Complete uppers maybe...same lower can run 7.62x39 or .300blk or 5.56 or 6.5 grendel.

6.5 grendel and 7.62x39 can share magazines.

I don't swap my BCG's around. I don't swap anything around really other than my EOTech...that has been on every rifle I have built at least once LOL. My go-to test optic.

Love my 300 BO, but the ammo is expensive, so it doesn't get shot very often. SO unless you re-load...

Well this is true, thank God I'm a reloader!!!!

On the other hand I didn't have to buy new mags for a .300 blk pistol as I still have old mags (colt 5.56 marks with alloy followers, and adventure line mags). Granted I don't have plans to get another AR, unless the ar74 psa plans comes out (then I'd get an ar74 lower and brownells ar180 upper), so having to buy more mags didn't appeal to me.

I have the option for subs and supersonic ammo, out of a 8.5" barrel. Which is better than 7.62x39 as far as powder burn goes. Not to say I never intend to get a short 7.62x39 (plan to sbr a draco someday), just that in the one AR I have it made no sense.

I've never shot a 300BLK but I've owned 3 different 6.8 SPCs and I love them. I've taken 3 deer with the caliber. First deer the round demolished the heart, 2nd deer the round demolished the shoulder and the 3rd deer the round when through the nose and out the ear. Needless to say, they were accurate for me and quite deadly.

I'm in Tacoma, shipping would likely equal it out for as much as I shoot it.

Not yet, only played around w/ 150gr. as I'm real new to .300... Sounds like I need to try some Speer 125gr tnt's. Next investment will be a short suppressor for it. I've got a flash can on it now, makes a difference redirecting the blast and sound forward...
