Editor’s Take:

We’ve put some rounds through the original MCX-Rattler around here, and it comprises one seriously awesome PDW machine. With the current state of the pistol brace favorable once more, look for manufacturers to start pushing pistol platforms again. The MCX-Rattler LT has the bones to run as an SBR or pistol, depending on your preference and tax goals. In any configuration, this one looks like a winner. We hope to get a true field test conducted in short order, so stay tuned!
