Improved AR-15 Lowers With Reliable Performance at a Great Price

Aero Precision has a couple AR-15 product lines – the M4E1 and the AR-15.

Lower Receiver Options

Aero Precision’s 2 main lower versions for AR-15 platforms in a range of models. The most recent and most popular models is the M4e1 lower receiver.

Complete or Stripped Lower Receivers

Aéro Precision offers lowers in a couple different versions: stripped and complete.

Aero Precision Stripped Lower

A stripped lower receiver is an ATF controlled other firearm. The stripped lower receiver requires a lower parts kit and buffer tube kit to complete it.

Aero Precision Complete Lower

A complete lower receiver is an ATF controlled other firearm. The complete lower receiver will have the lower parts kit and buffer tube already installed. It may or may not have a stock on it.

AR15 Lower Receiver – AR15 Gen 2 Model X15

Aero Precision’s Gen 2 (model X15) lowers are manufactured in 7075-T6 alloy. If you need a classic no-frills AR15 lower it would have to be this mil-spec lower.

AR15 Complete Lower Receiver w/ FDE MOE Grip & SL-S Carbine Stock - FDE Cerakote

The main difference between the lowers and mil-spec ones is the lower tension screw.

The lower tension screw helps make the upper and lower receiver a better fit, making it not rattle when moved. Many lowers don’t have this feature, it comes in handy when using another manufacturer’s upper. One quick turn of the screw will adjust the fit between upper and lower receivers.

AR15 Lower Receiver Gen 2 Colors

These lowers are currently available in:

M4E1 Lower Receiver

This lower receiver is Aero Precision’s most popular lower. It is a billet lower from aluminum alloy. The M4E1 lower supports standard AR15 parts, magazines, and upper receivers.

The good news is the lower also features the tension screw mentioned in the AR15 Gen 2 lower.
