AT3 Tactical AR-15 Cerakote Stripped Lower Receiver

The AT-15 is the AT3 Tactical take on the classic AR-15 lower receiver. This lower starts with a solid base of forged 7075-T6 aluminum construction. The same durable, lightweight material used from the beginning of the AR-15’s adoption as the M16 rifle ensures the AT-15 is as tough as they come. Plus, the AT-15 comes in a classic anodized black, and a full range of Cerakote colors that you can match with all your favorite colored parts from AT3 Tactical.

The AT-15 also features a deeper magwell flare than mil-spec lowers, making it easier to reload. This lower receiver serves as the perfect starting point for your next build. Add a lower parts kit of your choice, or piece together something that’s exactly to your specifications. The AT-15 will accept any part compatible with a mil-spec lower receiver. Plus, you can save a little extra cash right away if you add an AT3 AT3 Enhanced Trigger Guard when you buy now!

FAQ

Is this lower Mil-Spec?

The AT-15 uses 7075-T6 aluminum construction, and is availbale in a type 3 hardcoat anodized finish, which are mil-spec. The AT-15 also accepts all mil-spec AR-15 components. Most triggers, pistol grips, lower parts, buffer tubes, and upper receivers will have no issue fitting into this receiver. With the Cerakote options, the thickness of finish in some areas may make the fit a bit tighter.

What is Cerakote?

Cerakote is a ceramic paint and adheres to polymer and metal very well. Since the the lowers are painted, some wear marks may be seen on areas of heavy use. AT3 doesn’t warranty against Cerakote inconsistencies or the wearing of coatings. Our parts are Cerakoted using the official Cerakote colors.
