Quote History Quoted:
I have two, a relatively early 17.4" barrel model, and a more recent 20" barrel model. The 17.4" is slightly more accurate, and shoots about 1.7 moa consistently. The 20" gun basically shoots 2 moa, I assume because of more barrel whip.
I think the trigger is pretty great. My 17.4" gun had to go back to the factory immediately because of a hammer issue but has been perfectly reliable since I got it back (~1800 rounds so far). To their credit Kel-Tec customer service was great. My 20" gun has been perfect out of the box (~1100 rounds).
I know the RDB doesn't have the combat pedigree of the AUG, Tavor, and FS2000...but I find myself shooting my RDBs more than my three more storied bullpups. That being said I can't shake the distinct, let's call it commercial, quality of the RDB. I'd trust the RDB for home defense, but if I had to go spend time on a two-way range I'd still grab an AUG. I do wish FN or Colt or someone would use Kel-Tec as a design house.

They're more accurate than 3-4moa, but that's the practical safe bet because the barrel isn't floated. Nothing about the design suggests it can't do 2moa, provided the forearm pressure is consistent (but it's hard to do that in practice)
I really wish FNH or better yet B&T would buy a license for the design.
-modular, simpler, trigger group, select fire option
-floated front end
-simpler 3-pos gas valve with suppressed setting
-QD silencer mount brake
-fiber reinforced lower receiver
-titanium sheet upper receiver
-hammer forged barrel
-loaded chamber indicator
-cheek rest pad that can slide back to view/access chamber
-positive detent on magazine latch, and an articulated rather than flexible latch arm design (like a dog bone lever thing)
Ta-dah, modern service arm fit for any soldier, that probably only costs twice as much to produce as the current RDB.
