MILSPEC+ AR-15 Billet 80% Lower Receiver 

Our MILSPEC+ Lower Receiver in 80% completed form, to be finished by the end user. The MILSPEC+ is precision CNC-machined from billet aluminum at our precision facility in Spring Lake, Michigan. The MILSPEC+ builds upon exact MILSPEC forging geometry and combines it with the much tighter tolerances able to be achieved with billet receivers. Billet receivers provide a significantly higher level of quality due to the stability of the raw material versus a casting or forging. 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.

  • Domestically sourced Billet Aluminum - Raw finish (As-machined)
  • Flared magwell to improve mag changes
  • Billet quality in a MILSPEC forged form factor
  • Proprietary magazine geometry eliminates poor quality broaching
  • Fully CNC machined from aerospace material
  • Take down lug slot completed
  • 100% USA Made
  • Weight 11.4oz

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.

*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.
