FAQ

What kind of blemishes can I expect?

Blemishes are strictly cosmetic and may include minor surface scratches, small tooling marks, slight discoloration in the anodizing, or tiny forging dings. These do not affect the structural integrity, critical dimensions, or function of the lower. No two are exactly alike.

Is this lower ready to build?

No. This is an 80% lower receiver, meaning it is incomplete and requires additional machining (milling/drilling) of the fire control group pocket and other holes to become a functional firearm receiver. You will need tools, jigs, and knowledge to finish it.

Are blemished lowers final sale?

Yes. Due to the deeply discounted nature of blemished products, all sales are final, non-refundable, and non-returnable. Please review product images and descriptions carefully before ordering.
