AR10 & .308 Build Kits

WHAT IS AN AR-10 BUILD KIT?

The 80 Percent Arms AR-10 Build Kit is a convenient package with every major component you will need to build out an AR style rifle chambered in .308/7.62 x 51mm NATO. Build kits are for those who want to build their own rifle rather than buying a pre-built firearm from a manufacturer, or who don’t want to piece every component together themselves.

WHY CHOOSE AN AR-10 BUILD KIT?

The AR-10 is an extremely practical and versatile platform much like its successor the AR-15. It’s often used in long distance precision shooting, hunting, and tactical situations. AR-10 80% lowers allow you to build a larger platform rifle at home, without any additional work over a typical AR-15.
