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

    Venom defense makes a quality product! I've been using Venom products for several years and they never disappoint. I compared my latest purchase with a lower from 5 years ago and it's the exact same specs!

    80 lower

    The fit and precision is second to none. A billet lower at this price is just mind boggling. So much quality for mere scheckles.

    Lower and all related items

    Posted by Paul george on Aug 22nd 2022

    Besides the fact it took 4 months to get the product which is crazy to me because I just gave up on getting a response back… that will be the one thing that hurts your the most Better communication is key --------------- VDD Response: Hey there! Thank you for the taking time to leave a review. Every lower page is updated several times per week with next available to ship order numbers. This is written in the banner of the website, on the product pages, on advertisements, in emails, FAQ page, etc. It would be impossible to have every customer email me and ask for a personalized update on their order every day. Imagine the thousands per day. This is why I update the product pages, so everyone can see the queue, quite literally, in front of them at all times. I am transparent about all delays and all extended lead times. I am saddened you were let down by non-personalized emails; though, it is simply not something we can accommodate. I do hope you enjoy everything you received. Please note... customers should read lead times, follow all policies, search FAQ pages, and follow all instructions before reaching out to us. VDD

    80% lowers (raw)

    Posted by Blake w. on Aug 3rd 2022

    Honestly the over all craftsmanship is decent for the price but the finish is terrible. I've purchased raw unfinished lowers from quite a few companies and these by far are the toughest I've seen. The tooling marks are so prevelant they 100% will require sum sanding and finish work before being painted or whatever your final coating is going to be. Usually companies do a once over with the cnc to smooth out the surface before they're sold but these were definitely manufactured as quickly as possible and it shows in the quality. ---------- VDD Response: Bummer to hear you are not loving the finishing you need to put into your lowers. You did, however, receive the same 80s as everyone else, Blake. Detailed pictures of the products show all of the tooling marks each lower will feature and the description of the product, on all 80s product page, is as follows - Please note - while many of our customers enjoy the look and simplicity of the quote as machined quote aluminum, this finish is intended to be completed by the end user; therefore, machining marks will be visible.

    Better than expected

    Posted by Don on Jul 12th 2022

    I picked up a couple when they had them at $40. I was skeptical, but figured why not. I’m really impressed with what I got. They mate up great with several different uppers I have. A little snug on the rear lug pocket, so it’s perfect for making a wobble free fit with any upper. Took several weeks to ship, but they stated that up front and updated the ship list every couple weeks.
