So I am wanting something with more knockdown and for closer range than my 5.56 AR so am thinking of getting a 300blk. I didn't realize until I started looking how short the barrels are on these things, 7-8" in some cases which seems insane for a rifle round.

Recommendations on barrel length and manufacturer?

I dont need anything special and not looking to break the bank. My 5.56 is a PSA which has served me well but not sure if they are still a reliable brand. I went to their website and was surprised how cheap they were.

<-----@gmail.com. I have one for sale. BTW, you have to have a Tax Stamp to own a short barrel.

If it isn’t suppressed, prob best barrel length is 14 inches with a pinned comp.
it will perform great with a good barrel.
Can use big bullets subsonic or lighter weight bullets loaded to about 30-30 ballistics. Has very little recoil.
Really a great round for a kids deer rifle out to about 150 yards or so.
I have an ar and an encore w a pistol barrel and a contender w a carbine barrel.
Shooting deer w the pistol and varmit bullets loaded hot is a hoot.
At 100 yards, sounds like you hit them w a baseball bat.
Really shines suppressed.
Good can on a ar sounds like a 22. On a single shot carbine or pistol is really nice.

Only if it’s a rifle (SBR). If it’s a pistol you don’t. Last I checked, If you get a lower receiver and it’s listed as a pistol lower you can put a rifle upper on it, but not the other way around.

Not with a pistol brace ( the lower must be bought as a pistol, FYI)

Also, anything and everything AR is cheaper now. It’s a buyers market to say the least.

The 300 was designed to shoot from an 8” barrel. A longer barrel doesn’t really help, but it doesn’t hurt. I believe you lost a little in the ballistics with a rifle length barrel.

You can shoot super-sonic or sub-sonic rounds and those ballistics vary a good bit. Sub-sonic is great if you put a suppressor on.

Ygm

Okay so yall will have to excuse my ignorance, the AR platform is not something that I am well versed in.

I saw on the PSA website they called all there 300blk pistols however the looked like regular short barreled ARs to me. What constitutes making it a pistol?

Also yes I would like to be able to hunt with it so need a barrel that will give good accuracy at 100-150yrds.

Also I won't be running a suppressor, atleast not for right now.

The pistols utilize a brace that can look similar to a butt stock but it’s not. The braces are not collapsible and cannot be “shouldered”.

It’s simply a legal workaround for the ATF, which IMO shouldn’t be in the business of telling people how to use their firearm, but that’s another topic.

I have. 10.5” PSA 300BLK with a flashcan. shite is awesome.

Get a SBA3 brace. They’re awesome and let’s just say they’re very akin to a stock....

There are several adjustable braces and the ATF has said use doesn't constitute a redesign.

You can have any caliber as a “pistol” just need the brace or pistol buffer tube. The 300bo is best suited for suppressed and if your not gonna suppresse it their are better calibers to use as a “pistol” such as the 6.8 or 450bushmaster just to name two. Not saying you shouldn’t go 300bo just maybe keep looking and asking.

Neither of these statements are true.

I ended up getting a pistol lower because I wanted to shoot suppressed. Just be aware that subsonic rounds have the trajectory of a rainbow. It is also hard to get a bullet that will deform at all at such slow speeds. At standard velocities they do just fine though.
Really is a fun gun to shoot.

Cotton, why did you bring your gun to the golf course? If that's your lawn it looks like a damn fairway

You can shoulder a brace and there are adjustable braces

My statement was pretty clear that you statement was wrong.
