SBA3 brace buffer tube on a 9mm AR 15 pistol?

**WWGunslinger** · April 19th, 2018, 11:13 AM

I'm interested in the new SBA3 brace for my 9mm AR pistol, but wondering if I can use it?
I have a pistol buffer tube (completely round, not like a normal AR15 buffer tube). Can I use a normal AR15 buffer tube on a 9mm AR so I can use this brace?

i think it would depend on the lower you used or the manufacturer of your ar. i can only tell you that PSA 9mm lowers use a standard mil spec extension.

It is a PSA 9mm lower.

It's a standard milspec buffer tube so yes you can use it. There are a number of videos on YouTube regarding this brace already.

I have one ordered I'm just waiting for it to ship.

Maybe I'm not following, but I thought you could only use a PISTOL buffer tube on a PISTOL?

Or by "normal" do you mean a standard "5.56" AR15 pistol buffer tube?

The new SBA3 comes with a standard milspec buffer tube a d it's removable. SB tactical has addressed this and has been confirmed legal per the ATF at least for now.

Well, that makes zero sense, but... "ATF", so go figure.

Yeah I hear ya. I saw them address this in the comments of a YouTube video a week or so ago and they put all the info with days in when these things vs were confirmed with ATF. Unfortunately I cannot remember which video it was. I'm going to use one on the PAK-9 I'm working on and from what I see it should be excellent.

All these new adjustable braces have really blurred line on SBR, your seeing a lot of manufactures jump on it too, SBR and Supressors need to get off the NFA list.
