The absolute best pistol brace so far, bar none - SB Tactical SBA3 Pistol Stabilizing Brace for Mil-Spec Extension Platforms

The worst problem with all prior pistol braces is that they are friction fit to the pistol buffer tube so they are a little loose and the material is a little too rubbery for the (ATF correct) Proper and Occasional shoulder and cheek weld.

Also most prior pistol braces do not telescope so length of pull is an issue for most people.

This new SB Tactical offering eliminates ALL of that. The plastic is a little tougher, more sturdy, and comfortable, and the telescoping option is excellent. Plus the buffer tube it's attached to is carbine length which is a plus.

Please keep in mind that due to ATF restrictions on what constitutes a stock v.s. a pistol brace the SBA3 is permanently attached (pinned) to it's provided buffer tube. If you remove the brace portion from the tube, it is no longer a legal pistol brace because you just modified it and putting it back on a short barreled upper may constitute the making of an illegal SBR.

Best of all this is probably the most affordable and high value SB tactical brace yet. The Gear Works Tailhook is also well constructed and telescopes but is far more expensive. The SBA3 is a no brainer.
