Wow. I did not even think a 5.56 AR would go in battery with a 300 blk round. Learned something new today. Good job on the gun to Colt though, looking like it blew out away from the shooter like its supposed to, although that sucks for anyone right next to him.
Gator,
I need some lernin. Can you tell me what this…

Means?
Meh.. “Trigger warnings” ??
Way too many of ’em..

@Wip, go into battery generally means “cartridge in place and ready to fire”. In the case of this rifle, the cartridge is chambered, and the bolt closed.
I read up on how this would be possible, since the .300 BLK bullet is larger than 5.56 NATO, and thus should not be able to fit in the chamber. It turns out people have forced the cartridge in hard enough to push the .300 BLK bullet back into the case. Boom.
My advice – he should take it back to the gun shop he bought it from on the weekend during peak hours and ask the owner for his money back or for warranty to cover the repair. He should also record the conversation (for legal purposes of course) and post to TBP.
for people who don’t get it,
the 300 blackout (also known as 300AAC) is a wildcat round gaining more widespread acceptance. It’s a 30cal proj (same as 308Win) but loaded into a cut down 556 case. it doesn’t hold as much powder so it is not particularly fast but has similar velocities and stopping power to that of the 762 that comes out of AK (but with a different dia proj) the greatest advantage that it can be optimized for subsonic loads (and running thru a can) and its modularity with standard ar15 platforms.
this round allows them to run a 556 BCG, upper, lower etc with the only necessary change (and super important change) being the barrel.
i think it can go into battery because the overall length of a 300aac is nearly the same and the profiles aren’t all that much different, plus its popular to use full lead proj (over 200gr for subsonic) it could be forced inward.

personally i run 300aac but clearly color mark my mags to avoid these very types of problems.
that exploded upper was catastrophic but then there is possibility too:

harry p., nice explanation; pictures being ever so much more helpful.
Stuff I have read is that folks have jacked in a .300 blackout round into their 5.56, and whacked the crap out of the forward assist to get the bolt to lock. If you have to do that, it may be a sign that something’s up.
Rdawg & Harry p.
Hmmm, thanks for the explanation. So, DON’T use the .300 BLK? Harry made it sound like you can use it. I have wished I bought my AR chambered in .762.
Wip,
Harry was saying he shoots it, but only because his gun is chambered for it. Sounds like he has another AR in 5.56, and he keeps them straight by marking his magazines.
May I suggest an SKS for your 7.62 needs? Inexpensive, reliable, and I shoot the steel cased commie ammo, so I never feel bad leaving the cases on the dirt. Definitely lacks the “tacticool” factor though.
Wip,
300BLK is great round and runs well in AR’s as long as the operator isn’t a retard and does the proper checks.
its particularly a great round if you reload, you can get cheap bulk 556 cases, rework it to use as 300blk, the case pressures are low so the cases will last damn near forever as long as you pick them up at the range, proj options are plentiful and can be found cheap and they don’t use a ton of powder (like 30-06) so the reload price is super cheap. with inexpensive lacquered lead 203 gr proj my cost is $0.16/rd not counting the original case cost (that gets amortized over a number of firings).
i have multiple uppers chambered in each and I’m not worried about it because they are easily discernable, i train with them regularly so i am highly familar with them and i have clearly marked mags, plus, I’m not retarded (so i’ve got that going for me).
this guy would likely have a problem with 300BLK because his IQ is close to the temp of the room he’s occupying:
yes, i have both.
i have a legal SBR lower shown in the pic (approved tax stamp) and 2 uppers, the 556 is above to the right, the 300blk is installed, its an 8″ barrle with a suppressor (another approved tax stamp) attached with a rifle length rail covering most of it. with 203gr, 8.5gr of h110 its safe to shoot without hearing protection.

Greetings,
I have a love/hate relationship with this particular weapon having carried several versions around with me over the years. One of these that happens to be clean, oiled and with proper ammunition is a shooters dream as there is very little recoil and it is silly accurate easily up to 400 yards with open sights. They are light weight and will take more than average punishment.
If I were involved in some kind of long term fight where I didn’t have access to endless supplies of parts and cleaning materials then I might opt for something different. Of course, it always depends on the environment.
” I have wished I bought my AR chambered in .762.”
For the 300 it’s as simple as changing out a barrel.
You may be better off just buying a barreled upper if you don’t know how to do this, but every gun owner should know how to repair and modify his weapons so it doesn’t hurt a bit to learn.
FWIW, only thing I consider a serious round in the AR arena is the 50 Beowulf, Big slug with 50% more energy than a 12 gauge slug and a 200 yard usable range. You need the entire upper for that though, it needs a 7.62×39 bolt group even with the Beowulf’s rebated rim.
NickelthroweR,
Ive head the difference between the AK and AR design being explained as the AK 47 being designed by a solder and the AR being designed by an engineer.
They’re both good weapons, but the AK runs almost endlessly with little work or maintenance needed to make it run while the AR needs work to get it running right and a good deal of maintenance to keep it that way.
@Anonymous
That is a good way to describe it. Again, if I were, say, fighting as a insurgent and my weapon spent a lot of time hidden or buried then I’d want something other than an AR type weapon. If the fighting I was to be involved in was street fighting or house to house then I might want something different than the AR as the .223 does an incredible amount of damage to a person if it hits them but I might wish for something that could blast open doors or shoot through walls. If you are engaging targets that are further than 200 yards away and you have a good supply chain then nothing is going to beat the AR.
Ruger came out with a Mini-14 300 blackout last year. I have the 5.56/.223 dressed in pistol grip and folding stock (581 series–more accurate than the early Mini-14’s since it was retooled to tighter specs).
