AR-15 Billet 80% Lower Receiver 

Our VDD80 Lower Receiver in 80% completed form, to be finished by the end user. The VDD80 is precision CNC-machined from billet 6061 aluminum at our facility. Billet receivers provide a significantly higher level of quality due to the stability of the raw material. Forged lowers are ideally suited to inexpensively producing products in high volume, but the drawback is poor aesthetic consistency, unpredictable fit/finish and material instability - Say it with us: Billet is better.

  • T6 Heat-Treated 6061 Billet Aluminum - Raw finish (As-machined) or Cerakote
  • Flared magwell to improve mag changes
  • Billet quality in a simplified form factor
  • Proprietary magazine geometry eliminates poor quality broaching
  • Fully CNC machined from aerospace material
  • 100% USA Made
  • Weight 11.2oz

Our goal is to produce a quality product at an affordable price. Machining marks are perfectly acceptable and agreed to with the purchase of this product. 

Because 80% Lowers are not considered firearms by ATF, we can ship them right to your front door with no FFL required. Finished rifles must meet all applicable laws and you must be able to legally own a firearm. Compliance with all federal and local laws is YOUR responsibility.

We ARE NOT able to ship this product to anyone residing in the states of California, Connecticut, Hawaii, Illinois, Rhode Island, New York, New Jersey, Washington and Washington DC. Should an order for 80% lower(s) be placed for shipment to any prohibited state, the order will be cancelled and the card holder is subject to a 20% cancellation fee. 

*Please note - while many of our customers enjoy the look and simplicity of the "as machined" aluminum, this finish is intended to be completed by the end user; therefore, machining marks will be visible.

**Required machining to complete an 80% lower includes: Selector hole, Trigger pin hole, Hammer pin hole, Take-down lug slot, Fire control group pocket, Trigger slot

    Lower craftsmanship

    Posted by Tom Dye on Dec 17th 2022

    Reading some reviews I had some concerns but the lower I received was about as perfect as you can get, almost didn't need any work before finishing and it came very quickly, I think it was 3 or 4 days. I will make purchases from Venom again

    I have not finished it yet. I can only say, as a machinist and welder by trade, I'm very happy with the product and the craftsmanship.

    10/10 super awesome.

    They left the trigger guard flat across the bottom to make it easier to work on the receiver and the overall quality is amazing. Super awesome customer service as well. I will definitely be visiting your shop online again.
