AR-308 Billet 80% Lower Receiver 

Our VDD308 Lower Receiver in 80% completed form, to be finished by the end user. The VDD308 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
  • DPMS Style AR-308 / AR-10
  • GIGANTIC Flared magwell to improve mag changes
  • Threaded Bolt Catch Pin Hole (Pin included)
  • Billet quality in a simplified form factor
  • Proprietary magazine geometry eliminates poor quality broaching
  • Fully CNC machined from aerospace material
  • 100% USA Made
  • Weight 

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

    Soaked to get my hands on a couple of these, doing a 6.5 Creedmoor build first. Machining looks so nice and clean I almost want to clear it and run it. All the features of these receivers are so detailed, clean and precise it really makes for a great finished product, nicer in my opinion than anything else I've built. Shipping is quick and easy and VDD is second to none in the industry when it comes to customer service, communication as well.

    I Can't imagine the hours programming and testing. An absolute work of art you have to look really hard to find any kind of Minor detail you wish could be better. Sam does amazing work with the attention to detail that everyone hopes for.
