If you want to use your own extension, this brace also fits mil-spec receiver extensions.

Either way, the adjustment gives you enough customizability to ensure that this brace fits your body comfortably.

There’s a QD sling socket so you can carry your pistol comfortably, and use your hands for other things with your pistol slung. And, the L-shape design offers maximum stability in a variety of shooting positions.

The only drawback to this brace is that the arm wrap portion isn’t super supportive. So, it can feel a bit mushy when you’ve got it on.

If you want more support for one-handed shooting, the SB Tactical AR-15 SBA4 Adjustable Brace has a sturdier arm wrap.

Even so, the adjustability, sling attachment options, and price make this an ideal brace for anyone looking to add stability to their AR pistol.


  • Excellent adjustability.
  • Includes receiver extension.
  • Integrated QD sling socket.
  • L-shape design works well for multiple shooting positions.


  • Arm wrap isn’t super supportive.

Check on OpticsPlanet

5. Brownells KAK Shockwave Pistol Brace & Law Tactical Folding Stock Adaptor

Brownells KAK Shockwave Pistol Brace & Law Tactical Folding Stock Adaptor

Folding AR-15 Pistol Brace

Even though AR pistols are already fairly short, a folding brace makes it easier to stage your pistol in a vehicle, or store it in a tight space at home. The Brownells KAK Shockwave Pistol Brace & Law Tactical Folding Stock Adaptor gives you a pistol brace and a folding buffer tube all in one package.

Check on Brownells

First, the brace itself is the KAK Shockwave Pistol Brace, which we talked about before. It delivers great stability for a wide variety of shooting positions. But it does lack a QD sling socket and adjustability.

But, the real star of the show here is the included Law Tactical Folding Stock AdaptorThe stock adaptor adds a hinge to your buffer tube, so that it can be folded to save space.

This comes with some ups and downs.

Making your AR pistol smaller for storage and staging makes it possible to keep your rifle in a lot more places. 

However, you can’t fire your pistol with the brace folded. So, account for this when considering how long it will take to retrieve your pistol and get it into action.

Also, adding the hinge changes the length of your buffer tube a bit. For most pistols, this is no problem. But, some users have found that adding the hinge can cause reliability issues. So, this kit isn’t ideal for pistols that combine a short barrel with a long gas system, such as a 10.5 inch barrel with a carbine length gas tube.

However, the folding stock works with both direct impingement and gas piston systems. So, you’re not limited in the type of AR pistol you can use.

But, if you have the right pistol for it, this Brownells kit gives you a lot more options for storing and staging your AR-15 pistol, so you can have it ready when you need it.


  • Comes with a fully functional pistol brace.
  • Folding buffer tube adaptor gives you a lot more options for storage and staging.
  • Includes all the necessary hardware for installation.
  • Works with both direct impingement and gas piston AR pistols.


  • Brace isn’t adjustable.
  • Folding stock adaptor may cause reliability issues with some pistols.

Wrapping Up

If you’re building an AR-15 pistol, the brace you use is a critical choice for ensuring that your pistol is comfortable and capable of meeting your needs. If you’ve already got an AR-15 pistol, a good brace will make your pistol far more comfortable and easy to shoot.

In improving your performance on your AR-15 Pistol, take into account your pistol grip to have more stability and better handles.
