Tac-14 upgrade

by -

Not much wobble like a standard stock has and comes with a buffer tube. Great service like usual.

Quality brace

by -

Shipped very fast!!!! Ordered on Friday afternoon and received Monday afternoon. Fit, Form and Function is excellent.

Outstanding brace

by -

This might not be as cheap as some of the other braces but it's well worth it. It's not bulky like other braces and it's fully adjustable. I'll be replacing my other hard plastic braces with these.

Does the job well

by -

Surprisingly sturdy and light little brace which is comfortable in all aspects. I have detected only minimal wobble if that is something that would bother you and the positions lock very clearly and audibly when changing length. It is an interesting thing to note that the velcro strap seems a little springy like elastic. The hard plastic gives enough good space to consistently aim down the sights.

Brace to replace other braces


This is a great brace and is being used to systematically replace any/all other braces I’ve got or had considered getting. This is perfect.

The pistol brace to replace them all!

by -

Ordered it on Friday got it on Tuesday! For the price this pistol brace is very well built and rugged. Slapped it on my lower works great feels great! Primary Arms is a great company! A+

Best Pistol Brace

by -

The SBA3 brace is the perfect marriage of form and function, and it’s a BEAUTY!

Excellent brace

by -

Excellent brace, especially for the money. Very sturdy and reliable.

Is anyone even really second guessing this?

by -

We've seen this brace too long but for those of you still second guessing let me quell your worries. This thing is built like a tank and as light as a feather. My coworker let me beat the shit out of his before we put it on, slamming it on tables throwing it across the shop floor, etc. If you're building a pistol this is the #1 go to guaranteed.

SB Tactical's QC Needs To Step Up Their Game

by -

Probably the best brace on the market right now. However, ran into a problem while installing it. The buffer tube refused to line up properly, even after several attempts. I build AR-style rifles & pistols for a living, so this wasn't even close to my 1st rodeo. SB Tactical needs to pay a little more attention in their QC department. Primary Arms' service was fantastic as always though.

Before ordering make sure you don't need this

by -

Excellent brace, replacing a first gen Shockwave Blade which fits on a regular pistol buffer tube. My buffer tube has a step that bottoms on the lower receiver so does not require a castle nut. The SB Tactical brace DOES require a castle nut and it is not included in the kit. You will need to order one if you don't have one on hand.

Great Product, good price on sale

by -

I ordered this pistol brace to finish a 10.3" pistol and it is great. I had never been to excited about the price but after seeing it was on sale I ordered it immediately. As soon as the SBA4 goes back on sale I will order one to compare. Castle nut is not included so make sure you order one as well. Primary arms shipped my order on the day I ordered it and I couldn't be happier with my purchase.

neat brace

by -

What can I say, the SBA3 is true to what's been said before it is an amazing innovation comfortable to use, easy to install, and by far the best brace out there.

Clean and no rattle

by -

Good engineering and very ergonomic. No issues with lower attachment in terms of tube threading. No rattle. Tight tolerance. Exactly what you need and lightening fast shipping as always. PA is unmatched.


by -

Wonderful and innovative product. It does NOT come with a castle nut so make sure you have one.

Solid brace

by -

Comfortable, study, and easy to use.
<br>Save yourself the hassle and just go ahead and buy this brace.
<br>Worth every penny.

Works better than expected

by -

I was pleasantly surprised with the SBA3 brace. I'll be honest - without any prior experience regarding pistol braces I just ordered this based on a bunch of online reviews. It's very sturdy regardless of the brace design and feels great when you present the pistol.

Great product

by -

Very solid. Little to no slack in the parts. Best thing second only to a real stock. Also can’t say enough good things about primary arms customer service.

The Review Is Self-Explanatory


I ordered my second SB TACTICAL SBA3 AR PISTOL STABILIZING BRACE because the first one was so great in my 5.56 that I decided to build a second AR pistol......this one in 300BLK.
