AT3 Tactical Blemished AR-15 Stripped Lower Receiver – Black

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. This blemished version comes in a classic anodized black finish and features standard “Fire” and “Safe” selector markings instead of pictogram markings.

These blemished AT-15 lowers have a cosmetic chip or finish blemish near the hammer pin area. The blem does not affect standard AR-15 parts compatibility or normal lower receiver function. 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!
