The Evolve’s CARS mechanism automatically ejects the empty/expended magazine after the last round is strip from the mag (and fed into the chamber), and then automatically drops the BCG upon fresh/loaded magazine insertion, without requiring the shooter to manually hit a bolt catch/release lever, i.e., the “ping-pong paddle”. Obviously, not having to manually eject the mag or release the BCG can shave precious fractions of a second or even second in a match. Defense Review is therefore optimistic about the potential speed/performance advantage the Evolve can give competitive 3-Gunners–but warfighters, LEO’s and civilian tactical shooters will arguably benefit even more when their actual lives are on the line, assuming they can afford it (see farther down).
When it comes to military combat or civilian defense applications, i.e., martial applications, while your humble correspondent has been skeptical about the need for CARS for this purpose, we also believed that having it as an option certainly can’t hurt, provided you can disengage it if desired, the system/mechanism is designed to be “bulletproof” in terms of reliability under adverse conditions like cold, heat, mud, rain, sand, water, snow, etc., and the additional controls don’t get in the way or cause any problems. As long as you can switch the system off, and the additional parts/complexity doesn’t cause you any trouble, what’s the down side?
