FJB and The Tyrants

  • We at Tactical Machining are sick and tired of the “man” making up whatever rules they want to try to hinder law abiding citizens from manufacturing their own firearms.
  • While we are fighting that battle on the legal front we would like to introduce the FJB Logo Series 80 Lower receiver marked with Safe/Fire. (LIMITED RUN)
  • We are offering this to everyone at below our manufacturing cost to help arm as many Americans as possible in these tumultuous times.
  • No FFL required. Does not reflect FJB serial numbers.
  • Thank you all for your continued support it means more to us than you know.
  • Limit 5 per customer, and please no multiple orders.


  • Set screw not included, available for purchase.
  • ***Trigger guard not included***
  • Features

    • Forged from 7075-T6 aluminum by Cerro, these 80 lowers start from the best materials available.

    • Our 80 lower include an upper tensioning set screw hole to tighten the upper and lower fit to your liking.

    80 Lower

    Looking for 80 AR-15 Lowers? This is the most commonly built and the lower that started it all. Currently all of our 80 lower offerings are from Cerro and have the ability to be laser engraved as well as anodized. We also offer AR-15 handguards and AR-15 Upper receivers for completing your build. If you want all three, check out our 80 Build kits.

    Tactical Machining has been manufacturing firearms parts and accessories since 2008. Tactical Machining was the original manufacturer of 80 lowers for the AR platform. No FFL is required to ship this item as it is not considered a firearm.

    What is an 80 Lower?

    If you're looking for more information on what an 80 lower is we built a good guide explaining the 80 lower builds. We also encourage you to ask questions through the "ask question" button on our website. One of our experts will get back with you regarding an answer.

    What about the rest of your build?

    We offer support through your build once you have completed the 80 lower itself. If you're in need of gas port sizes, we list those. We also provide information on basic troubleshooting on your AR-15 as well.

      I’m debating on milking this one or keeping it as a display piece! Either way, it’s pretty cool!

      Excellent lower, worked as expected, some minor fitting may be necessary, filling/grinding, but that makes your fit perfect.
