New DIY AR…0% Lowers Now Available

80% Arms, makers of many types of 80% lowers looks to be throwing brickbats at the ATF by introducing the 0% lower.  Yes, that’s right… Your very own billet aluminum block to mill into a completed lower.  I must admit, when my brother Chris emailed me a link to the page, I literally fell out my chair laughing.  So, if you would like your own 0% lower to turn into your very on AR with just a little bit of work, check out 80% Arms page here.  Take that ATF!


We are pleased to offer the finest 0% lower receivers in the world. What is a zero percent lower you ask? As the name suggests, it’s a lower receiver that is zero percent complete. In other words, a solid brick of aluminum. Our lowers start off in the form of these bricks and are machined to 80% completion on our state-of-the art 5 axis CNC mills. These 0% lowers are heavy and have sharp edges. They could make a good weapon if thrown at an attacker. Don’t tell the Obama administration, lest they try to ban these very scary things.

    This is a step in the right direction, but what I’m really looking for is some ore so I can shape it into a zero percent lower. Anybody know where I can find some?

    • in the ground?

    • I believe you are looking for a -50% lower… Those can be had with a shovel and pick…

      • gunslinger

        if you have your own rocket ship, you can get a -100% lower by going out and lassoing a star cluster to create the atoms you need.

    Now let the innocent people fear me! And my assault…aluminum..block…thing.

    Its…got edges and is…pointy. That’s, like, deadly, and stuff.
    It’ll hurt a lot if I throw it at something and hit it!

      Just the thing for an OC demonstration!

    • Justice

      This Assault Block is perfect for Open Carrying to Chipotle and Starbucks!
      I just checked the website, its $29 each with $8 flat shipping. I’m buying a bunch to OC my assault block when I get my coffee and lunch =]

    Aluminum conducts electricity, and electricity can electrocute someone. I’m writing my Congressman right now.

      it’s a ghost gun, it has the ability to disperse a 30 magazine clip in half a second

  • wetcorps

    Ha ha ha awesome. Sometimes a little bit of funny doesn’t hurt in a generally very serious industry 🙂

    • As long as it isn’t taken too far, like the zombie trend.

      • Agreed, but in reality it brought people into the firearms world that might not have thought about it before. So as much as those of us that follow the firearms community got sick of it, it wasn’t all bad.

  • Payce

    Ah man, that’s great. I love it when companies have a sense of humor.

  • herb

    “Kaiser Aluminum” still on the side, lol!

  • Eugene Berman

    I hope they have a letter from ATF…

  • Munkfish

    Sad thing is this cost more than the complete-except-for-anodizing lowers that I got from Palmetto State Defense. Didn’t stop me from buying one though.

  • To Tin Fung

    Erm what’s the point of buying a brick of aluminium if you don’t own a CNC?

    • I think the concept here escapes you 🙂

    • Aurek Besh

      Machine tools also come in manual versions. 🙂

      ^^ The noise of the joke flying over your head.

  • Seth Hill

    The term “firearm” means

    (A) any weapon (including a starter gun) which will or is designed to or may readily be converted to expel a projectile by the action of an explosive;

    (B) the frame or receiver of any such weapon;

    This will still be deemed a firearm: as it can be used as a weapon, will be converted into something that can expel a projectile, and will be a frame/receiver of a weapon.It is all about intent and not about what actually is a firearm. This would be akin to a frame of a car being considered a car because it could be converted into a vehicle. The above definition would also make a piece of pipe a firearm.

    The definition needs to be changed to something like a collection of parts assembled to expel a projectile by the action of an explosive.

    I think Lowes sells sten gun receivers on the plumbing aisle. Better not tell ATF….

    • Eric S

      There was a bill a while back that wanted to make 80% receivers require transfer paperwork. Part of me wanted it to pass just for the epic backlash of things like having to make Lowes file for a FFL.

  • glock9handy

    This is a 0.001% lower. A 0% lower would be hydrogen atoms still floating around in the sun. Actually wait, come to think of it, a true 0% lower would be the singularity at the beginning of time.
