For sheer versatility, it is hard to beat the AR-15 platform. An AR can function in a multitude of roles — defending your home, hunting varmints, or competing in Service Rifle or High Power matches. If you’re planning a new AR project, it all starts with the lower. That’s the part that carries the serial number and is logged into the books of your FFL. Once you’ve got your lower, then the fun begins — you choose all the other components: trigger group, stock, handguards, and upper.

Right now, Brownells is running a great deal on stripped lower receivers. You can get an Aero Precision Stripped Lower for just $59.99. It’s hard to beat that price. Aero Precision is a good manufacturer that makes durable and dimensionally-correct lowers. And these lowers are backed by Brownells’ 100% Satisfaction Guarantee.

Holes, inletting and pin locations have been cut to final dimensions and accept standard AR-15 magazines and components. The safe/fire switch position indicators are stamped on the receiver. FFL required for purchase.
