For some situations, an AR-10 in 308 Winchester just isn’t enough gun. If you feel the need to stretch your legs and shoot out to 1,000 yards and beyond, but with quick follow-up shots, you need Miller Precision Arms’ new .300 Win Mag AR-10 style rifle.
The gun may be 80% parts compatible with existing AR-15 and AR-10 parts, but the oeprating mechanisms are all new. The magazines are stretched and polymer walled, but with an aluminum base plate and 10 round capacity. The barrel is a cut rifling Krieger barrel tailored to your desired length. The camo pattern is optional. And the whole thing weighs just a hair more than your bog standard AR-15 rifle.
The gun comes either as a standalone rifle for $5,400 or as a kit with multiple magazines, rangefinder, optic of your choice, spare pins and springs, and all in a convenient case for $15,000. As the MPA folks say, it’s a sniper in a box — minus the trained trigger finger.
