ok, a few facts about the lightweight ammo

"The rifle—and 20 rounds of ammunition—weighs a total of 9.7 pounds. By contrast, the standard M4A1 (pictured above) and 30 rounds of ammunition weigh 8.74 pounds."

"the 20-round magazine is at least as long as a standard M4A1 30 round magazine. While a 30-round magazine may be possible, too long a magazine blocks the user from shooting while prone. In fact, it appears polymer-encased telescoped rounds are actually wider than brass rounds. While each round is lighter, it takes up more volume than its brass-encased peers.

"If that's the case, then Textron's design choice is understandable—if you must carry fewer bullets anyway, you might as well make them hit harder. There are always compromises in small arms design, and the new rifle is no exception. Is losing a third of available ammo and adding three quarters of a pound to the rifle worth a 300 percent increase in bullet energy? Decisions, decisions.
