300 Blackout???

[alfred1222]

I agree here. On a suppressed SBR it's gonna be hard to beat.

That's what the cartridge was designed for, right? Close quarters suppressed fire??

Without any changes in gassing? I'd expect to need to be way overgassed when running 7.62x39 numbers in order to get subsonic to work properly.

A lot of people running them in free states that switch between super and sub are using adjustable gas systems.

Not really.

The cartridge was designed to replace the .45 in close quarters suppressed fire and also the .223 for medium range engagements. The point was to have one weapon system capable of both objectives, basically combining the MP5SD and M4 platforms.

4.6 and even 5.7 are better for a pure CQ suppressed role given their compact size and zero recoil.

Large PD around here dumped their 5.7s SMGs

I paraphrase the guy I talked to
"We had to swiss cheese the ****er to stop them".


How accurate this is, I don't know, but they are back to SBR'd m4s.
Just found the perceived feeling on it funny.

Why does everyone compare the 7.62x51 to the blackout?

because its a rifle round

and im willing to bet that 99% of the people here CANNOT OWN A SUPPRESSED rifle

so it just becomes a regular old rifle...not a CQB gun

so its an over priced....hard to find ammo gun youll hardly ever shoot.

what "luck" do you need for 7.62 nato ? recoil is nothing in a M14 platform....have you ever shot one ?

[SA227driver]

Just built a 9" 300 Blackout pistol with the Sig Sauer SB15 Arm Brace. It is an amazing "rifle". Nice and short, quieter and softer than 5.56 and just now waiting for my silencer to arrive for it. So far in my own testing I've found that Pmags work the best for the most reliable feeding. I haven't tried to many USGI style aluminum mags, just some C-products mags that did alright as well.

Just go 7.62x39 and shoot all you want ! Ammo is like 230$ a 1k rounds

My understanding in a CQB shorter is better correct.

A CA legal Ar15 w pinned 14.5"bbl in 300AAC OAL= 31"
Ak-47 with slant break= 34"
Socom 16 = 37"

All 3 rifles are .30 cal.
The 300AAC has the least recoil.
How is the AAC round "not a cqb gun" just because the lack suppressor?

We all know that rifles are the most effective against people. In a home defense situation i would prefer the AAC over any other round.


I have shot a M14 (yes the military version) and am aware that the recoil is not bad. But you can't compare it to a 300 AAC

[bigred1]

suppressor has no bearing on CQB. CQB really just means from 0-50m. Now you become more effective when your weapon is shorter only because it makes you a smaller package ergo more maneuverable. There is no such thing as a "CQB" rifle.

300 blk shines in the fact that there is no major velocity loss/gain between a 7" and 16" barrel. Meaning that you still get that big thud @50,100 and 150 from a pistol/SBR that you do from a full length carbine.

Doesn't surprise me. Those 4.6 and 5.7 rounds are designed for burst fire where the intent is to put a half dozen rounds in a small hole. They were a NATO design spec for PDW weapons capable of penetrating body armor. Damage to the flesh was always an issue with AP rounds, which may be why NATO never actually accepted the weapon systems. Can't complain about the success of the MP7 though.

For a PD, that just means bad PR. I honestly don't feel 223 is much better, but rarely does a PD pick a weapon system based on performance, there are far too many budget and political decisions to be made first.

From what I remember of the conversation, they were not issuing the AP stuff. Not sure if the non-ap is any better though.

For 223, they are running Gold dots and Hornady TAP.

The non-ap stuff is hideous, it's basically plinking ammo for civilians. Yeah it's no surprise that they have better luck running good HP ammo in their AR's.

Same with the guys here. They went back to the m4

The thing with CQB is not the round it shoots, its the length of the barrel. a CQB gun should be between 7" and 10"
