Command Arms Accessories have designed an interesting AR magazine called the the CountDown Magazine (CDMAG). It displays a self-illuminated round count indicator that as well as showing the number of rounds it also changes color. 20 – 30 rounds have a green background, 10 -19 have a yellow background and less than 10 have a red background
It also includes an indicator underneath.
Interesting concept. No word of pricing or if it meets STANAG specs (compatible with all firearms that accept STANAG magazines).
Hat Tip: American Police Beat.
