The SB PDW brace is available at PSA without the LPK for $299.
In stock, now.

I just picked this up. I added the sites, Magazine grip, and forward grip.

Very nice

I'll second gearhounds post...that does look nice...we will need a range report

Edit to add...if anyone is considering in building an AR pistol, do it, they are a blast to shoot and very handy...I wouldn't put it off much longer though with things being the way they are.

My arm brace arrives in a couple of days. Now, to think about the upper.
I want this pistol for discrete carry in a backpack or similar. That means a barrel shorter than 11.5", probably.
How short is too short? I want reliable function and I also don't want to lose all the velocity in a noisy fireball at the end of the barrel.

What's the sweet spot for a 5.56 pistol? 9" or 7.5"? I just don't know.

Picked up my SB Tactical PDW brace this week.
Need to order my LPK and slap the 9mm upper on and see how it runs.

I decided to go with a 7.5" 300 BO upper. It seems like more pop from that barrel length, in that caliber.

I went with the Maxim Defense brace and it is built very well. I may try an SB Tactical to see how it compares.

When I started looking into building my SBRs, it seemed the consensus on barrel length needed to allow time for all the powder to burn was something like 9” in .300 blk and 11” in 5.56.....or something pretty close.

I’d not mind building a PDW, but like you, I’m kinda curious as to what would be a good round for it.

FWIW, when I built an AR pistol with the same intention of being able to put it in a backpack, I went with an 8.5" 300 BLK upper (Sig M400) with a Law Tactical folding stock adapter and a Gearhead Works Mod 1 brace.

My thought process was that 300 BLK is optimized for the shorter barrel, and to fit in a normal-sized backpack, the overall package needs to be as short as possible. With the stock folded, the pistol is exactly 19.5" long.

That PDW brace looks very nice.

BTT with a new question.

BTT for a new question:

How reliable is the Dolos takedown system? Has anyone put significant rounds through it? Put it through a class? Is it a gimmick or a solid piece of equipment that you would rely on in the gravest extreme?

While I have no experience with it, I've heard positive things. I've watched some reviews and such and considered one for a while. My focus, however, is just intended use. With an AR pistol, I have a folding stock adapter on one of mine, and that lets it fit in my backpack for storage/carrying and it has a more rapid-deployment than a takedown system. I'd also worry a bit about the gas tube getting bent when broken down.

I have no direct experience with it, but from what I've seen it is a solution looking for a problem. They advertise getting into action in 10 seconds or less. If I need, or want that, I can easily put an upper on the lower, push in the takedown pins, insert a mag, and charge the gun, in 10 seconds or less. All without worrying about damage to the firearm, which the manufacturer highlights as a possiblity. If not the very rare case you needed to rapidly deploy your rifle,with the adrenaline pumping, will you really be able to, "ensure that the lock collar is securely attached to the tri-lug and there is no freeplay in the barrel before shooting your rifle, take care to protect the gas tube when your barrel is separated from the rifle,
be careful when inserting the gas tube into the upper receiver, because it can and will bend bend if improperly installed?"

how effective will that rifle be in a high stress incident, if you damage your has tube?

Just my 2 cents. YMMV.

Just a question, a little off target, is the 9mm AR/M4 platform starting to take a larger part of the market
Is the pistol with brace the mass that fills the small void created by the decrease in the 5.56/300bk share of the market for the same purpose.

Back to the discussion, the 'forearm' brace is just a necessary evil for me. I actually prefer the plain padded extension tube.

I have a Dolos on a 300blk and a 5.56 barrel (10 & 7.5 respectively), the pistol also has a LAW adapter.

I love it. I chose the longer 300 barrel to easily tell the two caliber a apart.

It's not designed to react to immediate use, as it takes ten or so seconds to deploy.

The draw to it was the ability to carry it covertly. I use a laptop bag. No one knows any different.

A friend carries his in a Herters range bag. It looks like a camera bag. If you didn't know what Herters was you would not think "gun"

Where are you guys buying from?

I've been looking at PSA but they're still talking about a minimum 10 day wait to process orders. Then add in shipping time.

PSA quotes 10 days. Most of my recent orders have been received in less than that. 2-3 days plus shipping time has been my real world experience, in March.
YMMV,

Bruce

I thought I'd share my experiences as of today. I have been shooting a 7" 5.56 that I pieced together a year or so ago. No issues at all, and I used the KAK brace on a regular pistol tube. I like it alot, enough that I went on a hunt for something "nicer" to add to the collection. I came across a used Sig 516 10.5 complete upper, and brought it home. I started looking at new lowers, and found a source for Sig M400/516 stripped lowers. Snatched it up, and was overjoyed when it arrived. A couple months go by, and this past Saturday night I ordered the SB PDW stock. It was a long 5 days waiting, but it was in the mailbox Friday afternoon. Opened it up, inspected, and it looked great!! I had already built the Sig lower, minus the buffer tube, so I grabbed it and the SB and headed to the garage. I put the mag block in the vice, threaded the supplied buffer tube in the lower, and torqued it down. All thats left now is adding the "brace" onto the buffer tube. Perfect fit, and it looks awesome. Quality is top notch.

Now the kick in the crotch.... If you notice, which I did not.... The Sig lowers have built in QD mounts in the rear of the lowers. They are located EXACTLY where the two sliding rods move along the sides of the lower. So...the stock fits, but it will not collapse at all. It can only be used in the fully extended position. Pretty bummed...

With that being said, now I'll just build another one!!

My friends and I buy direct from PSA, off the website. Some stuff comes quick, some does not, but I'm usually not in a rush to get "toys."
