Almost a step backwards in styling...and the lightning cuts on the lever won't help that.... - SB Tactical SBA4 Stabilizing Brace for Mil-Spec Carbine Extension Platforms

This is very well made, but the rubber straps on the sides are a "No" for me (similar to their earlier braces). They provide some stability, but not enough when shooting to make me ditch the SBA3 - which I love. I have the VSeven custom strap and it keeps the rubber on the rear of the stock from collapsing as good or better than the upgrades found on the SBA4. The SBA4 does have a better cheek weld, but, personally, I don't have a problem with the cheek weld on the SBA3.
