AR10 & .308 80% Lower Receivers
What is an AR10 / LR 308?
An AR10 (also known as an AR-308) is one of the most versatile high powered rifles on the market, shooting the venerable .308/7.62x51mm round. It’s most commonly used for long-distance target shooting, hunting, and other precision rifle work. AR10 rifles are capable of shooting out to 700 yards and beyond which makes for a great sniper or hunting rifle. The AR-10 is also a great option for hunting due to its ability to take down nearly any commonly-hunted game in North America. It’s mostly used to hunt deer, elk, and pronghorn. Out in the desert, it makes a great coyote gun across wide-open distances.
WHY BUY AN 80 PERCENT 308 LOWER?
An 80 percent lower receiver is not considered a firearm until the remaining 20% of the work is done by using one of our Easy Jigs. There is no need for an FFL, transfer fees, and or registration. They ship directly from our warehouse right to your doorstep!
