Just took this off to go with a lighter profile.
Factory AAC .308 1:8 twist 18” medium contour barrel (lighter contour than the 20” one that comes on the Remington rifles)
Factory threaded 5/8-24 with lots of meat in the shoulder.
Fired less than 50 rounds. Excellent accuracy with 180gr Lehigh subs.
It is melonited from the factory but I also had it cerakoted flat black so should be impervious to weather.
No thread protector
