Really like what KAK did with the lighter and smaller 2.0 version of the brace! They look particularly nice folded, and the FDE color is a pretty good match with my Aero receiver. Installs easily too... just like a regular buffer tube assembly, then the brace slides over and secures via the multi-position latch. I looked at a lot of braces, and I ultimately decided to go with the one from the folks with not one, but TWO ATF letters of approval on the device and its use. NOTE: The carbine-esque tube that comes with the 2.0 is a proprietary tube with slots (not holes), and the blade will NOT clip onto your regular carbine tube. The little metal bar that acts as the latch is also a little hard to operate and will hurt a non-gloved finger with continual adjustments. Some oil on the tube and a little use should continue making that better over time.

The pin seems nice and sturdy, with a really nice fit on an Aero Precision AR15 lower in FDE cerakote - there is a minute amount of extra length and therefore wobble due to the different tolerances of various lowers. The push button mechanism is solid and isn’t going to budge unless you want it to, but I’m still looking for an R-style hitch pin that’s small enough to secure it. Maybe the best part is you get to avoid another spring + detent with finicky installation - no spring flying out the back out your receiver from under the rear plate, so it makes complete removal of the pin(s) as easy as just another button press. This .250 diameter pin will fit MOST “mil-spec” (or commercial) AR15/M4 type receivers, but if unsure, just ask your manufacturer or check KNS’ website.
