300 AAC Blackout Questions

Post by Alohakid » Wed Jan 16, 2013 2:05 pm

Aloha again,

From my 'blowback" post, noted that I've not shot nor kept up with the AR15/silencer world in 3 years. With that said, my questions below:

1. With my existing Rock River .223/5.56 and AAC Ranger II, may I shoot 300 AAC Blackout ammo with no modifications?

2. If modifications are required, must I A.) Get new can and B.) 300 AAC upper?

As always, your comments/suggestions are greatly appreciated!

Aloha,
Kid

300BLK will NOT shoot from a 5.56 gun... It will blow up! Also, it will not fit through your Ranger. 300BLK is .308, your RR is .223, and so is your can. At a minimum, you will need to swap out the barrel to 300BLK, but I recomend a whole new upper and a new can.

Will a 5.56 bolt even close on a 300BLK round?

I have not tryed it, and won't but I have seen (on the net) at least two guns blown up from putting 300BLK in 5.56 guns. I do not know if they forced it in with the FA or not.

Krammes - Great stuff Sir! Must most move quickly to order before obongo and minions trample on our gun rights. Hell, most likely have new can in hand before finding 300BKL ammo! :wink:

J Krammes & 700PSS - Thank you both.

Holly mutha of pearl - 7.62SDN-6 = $1,050.00... so much for my bonus going to just a new 300BLK build with Aimpoint Micro H-1... maybe I can cut laws for 5 bucks a yard as I did as kid in the 60's....

Here is a good thread about using the wrong ammo in your gun.

Not my picture, i cant remember where i stole it from, it just looks cool...
It is almost artistic the way to baffles peeled the jackets off a few bullets before completely clogging. I think the caption was that this is what happens when you fire 300BLK in a 223 can...
