Home Forums Hunting & Shooting AR and Tactical Rifles SBR with a can

I know a lot of this has been gone over, I've read the threads as they came up because I was mildly interested, but now I'm really interested and may very well take the plunge.

Would like to get a 300 blackout SBR, with a can. I've googled and read a bunch online, but would like to hear what the 'campfire has to say. Looking for feedback from them that either have them, or are familiar with them.

Obviously this ain't going to be cheap, but price is certainly a consideration. Would like to hear recommendations on brands and bbl lengths. From what I've been reading it seems like a 9" upper might be the way to go? Thought about building one, but having not built one before and this being a finicky bastard according to some I figured I'd just buy a ready made upper.

Thank you

You gonna run sub and supersonic? That seems to be an issue for some. I wouldn't see the sense in going supersonic, but that's me.

Would like the ability to do both, but primarily sub.

Build it sub, run it sub.

When you want super, get a better super round.

Just my take on it.

Yup keep it sub and simple.

Good advice.

I wonder if you can set them up so that they will cycle subsonic with a suppressor and function fine without a suppressor and supersonic ammunition? Then the trouble is you need one of those Eocraps made for the BO with two dots in it.

scope with knobs takes care of anything....

Cycling and optics are secondary issues.

The first question you should be asking yourself is, what am I going to use this for?

That will dictate the specs of the rifle.

Why would anyone want to shoot the .300BO supersonic out of a 9" bbl?

Having answered that, form follows function.

I have a Noveske 10.5 upper that I leave my suppressor on. I shoot subs ad supers. Deer die both ways. My farm is in suburbia and noise reduction is pretty good with the suppressor on shooting supers. The rifle feeds , ejects, locks on last load regardless of the round, sub or super.

Use/have used several Noveske's, AAC's and a Honey Badger or two. They all run subs and supers without issue.

I am not sure why people act like supersonic ammo is a stupid idea in a 300 BO but it can only be from ignorance or misunderstanding. It's a system, and the ability to shoot subsonics and ammo with 300+ meter range by just switching mags is huge if you need subsonics. Subs are the niche, supers are the mainstay.

That makes sense, if somebody has a need to do both.

Is there really any need for the extra expense of a SBR now that the Sig brace is available?

Sometimes I wonder if people here live in a cave.

Sub and super, suppressed or not, is how the 300 BLK AR platform is meant to be set up. A gun that won't run under some of those conditions, with no changes, isn't set up "as designed".

To the OP - easy button is a 9" AAC upper. They do cost a bit more, but are very light weight and good quality, and since it was AAC that pioneered the standardization of the round and it's "dual purpose" nature, you know it'll be set up right.

BTW, the easy way to play while you wait for the SBR stamp is to build it as a pistol, then just add a stock when the stamp is approved. Like many others, you may decide the stock and SBR paperwork aren't necessary anyway. I left mine as a pistol, and run it with the buffer on my shoulder same as if it had a stock.

You could give me an AAC. But I'd just sell it.

Honestly.... No. While being able to change buttstocks is nice and I prefer the "feel", the Sig Brace (especially V2) is functionally the same. And it has the benefit of being legally a pistol... CCW etc.

Why would you build a SBR ($200 tax stamp) and use a can (another $200), when you can build a pistol with the can in the float tube and a Sig Arm Brace and only pay tax on the can?

One other thing about subsonics that I have noticed is if you want to hit things the size of beer cans, you gotta have your dope dialed in just about as well as you would your 22LR.

You can kiss that "hold on fur" schit good-bye.

Whatever that's worth.

The quietest version will be a bolt or break action gun. I threaded a 30-30 handy rifle and it shoots subsonics very well and is quiet.

Of course the AR is plenty fun. I have only shot this poor coyote with mine but the 220 subsonic does not impart the hydraulic shock like a 223 does.

I didn't say shooting supersonics out of the .300blk was stupid, I questioned a 9" bbl if one intends to shoot supersonics much.

The fact you think a .300blk has a 300 meter range with a 9" bbl is interesting. Most of us here live in the real world, not the faux tacticool world.

A supersonic .300blk round out of a 9" bbl is barely above subsonic at 300 yards. I realize you've probably never killed a large mammal with a subsonic in your life, but advocating a 125g bullet for use at or around subsonic velocity, at that range, is ignorant and foolish.
