AR15 Stripped STS Lower Receiver

Manufactured in the U.S.A by Aero Precision

The Aero Precision AR15 Stripped STS Lower Receiver (Short Throw Safety) is the perfect lower to start your build. Custom designed markings accept short-throw safety selectors. In doing so it still keeps mil-spec dimensions and correct component interface. Furthermore, selector markings will work with 45, 60 or 90 degree safety selectors.

AR15 stripped STS lower receivers are marked and milled to accept short-throw safety selectors. No worries because they will work with standard selectors as well!

Arm or Ally is proud to team up with Aero! Since they make their products in house, they offer a great value without the extra costs. So, be sure to check out our Aero Precision Bolt Carrier Groups, and upper receivers offers a fine selection of Aero handguards. Another interesting offering are the handguard combos. Furthermore, Arm or Allyoffers barrels by Ballistic Advantage. An absolute great deal at even better pricing. Lastly, BA guarantees sub-MOA accuracy. Nice!

Federal law requires that you be 21 years or age or older to purchase a stripped receiver or frame. If a frame or receiver can only be made into a long gun (rifle or shotgun), it is still a frame or receiver not a handgun or long gun. However, they still are “firearms” by definition, and subject to the same GCA limitations as any other firearms. See Section 921(a)(3)(b). 18 U.S.C. Section 922(b)(1) makes it unlawful for a licensee to sell any firearm other than a shotgun or rifle to any person under the age of 21.
