Two years ago Remington jumped into the modular precision rifle platform with their MSR line, this year FN hit back hard with their Ballista rifle. Easily convertible from .338 Lapua, .300win mag, and .308. Swapping out calibers can be done under 1.5-2 minutes, and is done so by loosening 4 captive barrel screws, and uses a self-adjusting bolt for proper head-spacing. The gun utilizes a composite mix of aluminum, steel, and polymer stock, with folding stock (adjustable), and more rails then AMTRAK. Coming in around 17lbs this looks to be a strong competitor in the military precision platform market.
