A not-so-new notion seems especially apropos to our JP pistol caliber carbine—the only thing better than a clean GMR-15 is a dirty one. And the more, and more recently dirtied, the better.
Lightweight and light duty are easy to equate, but imputing that notion to either the Xanthos-Lite 6.5 mm Creedmoor or the Balios Lite .22 Long Rifle from 2A Armament would be a heavy-duty mistake.
