Someone talk me out of the .300 BLKout

[Wisehybred]

I like the idea of a bit longer barrel. KAC rail on the AAC is putting me off a bit. I really don't need the longer barrel as this is a "for fun" gun. Would anyone advise against 10" and under barrel lengths?

SBR = Short Barreled Rifle
BCG= Bolt Carrier Group
AAC= Advanced Armament Corporation

Most of what we are discussing are short barreled rifles.

So are all the 300's SBR's? Do people use the 300 on a fully size AR?

No
Yes

There isn't significant gain between the 9" - 16" barrel. That's why a lot of people opt for the shorter one. It's why I did at least. Always been enamored of sbr's

I agree. But my 16" is accurate.
Can't wait to build my shorty upper and see how it handles, because 16" plus suppressor is a lot of forward weight.

Technically speaking, longer barrels do not make the gun more accurate unless you're using iron sights 'cause you have a longer sight radius. Longer barrels give you more velocity and therefore will give you a flatter trajectory if all else is equal. Just sayin'........

You're right. That's why my .308 is 18"
I guess I should be a bit more clear in my choice of words. My 16" 300blk will shoot lights out with no troubles out to 100 yds using cheap Magpul flip ups

The stamp is for the can not the firearm it's attached to correct? If so, bring the can and you can try before you buy.

Winchster, usually they are two stamp rifles. One for the can, the second for the SBR'd rifle. So you got $400 in taxes along with the parts.

My stamp is for my can. Haven't sent off for the SBR, yet.

Thought so, just clarifying. Point was if he's got a can that'll thread on my AAC he can see what he thinks at Hicksville.

I'd fall over dead if I got a baffle strike doing that.

 

[winchster]

Shows how much I know about cans. Didn't realize that was an issue.

It could be...if the threads on the barrel are off a bit, the bullet could strike the can's baffles. That is a sure fire way to ruin your day.

I'm sorry, I thought you wanted to be talked out of it. Oh well, I don't think I could have succeeded anyway. I love mine.

2 stamps.

I have both a 9" and a 16" 300 BLK gun. The only real difference I have noticed is that the Remington 220Gr subsonics are loaded pretty hot and do not stay subsonic out of a 16" barrel.

 

[deemus]

So, if I bought a 300 Blk, I could use it on my regular AR lower?

Yes*. Same lower, Bolt and magazines. That's part of the attraction.

Unless you are getting a short barrel, then you'd need an AR lower registered as an SBR.
