The TB-9 Billet lower receiver is precision machined in-house from hi-grade 7075 billet master plate to milspec standards making it compatible with most milspec 9mm uppers. Features a broached mag well and milspec 8625 type III, class 2 hard anodized. All that is left to do is machine the fire control pocket, for the trigger group and drill a few holes. Once complete you will have a fully functional TB-15 type lower.
The TB-9 accepts Glock OEM and after market Glock style magazines. The magazine catch is included and is machined from aluminum billet and hard coat anodized. The ejector is included and is secured with 2 set screws. The bolt catch hole is threaded and and screw for installation is included.
This is not a completed receiver and still requires machining to be done in order to have an operational firearm.
NO FFL is required for purchase, item can be shipped directly to your home.
As determined by the firearms technology branch of the ATF, this lower receiver is not classified as a “firearm” as defined by the GCA of 1968.
Ordered this 80% after looking extensively on the internet and talking to the owner via phone. Transaction went smooth, just a little slow due to a family member’s recent surgery, so understandable. I used a Tactical Machining jig that I modded for this 9mm 80%er. Only a little bit of machining on both sides was necessary to clear the mag catch pivot area and the cosmetic re-enforcing by the front pivot/take down pin. Very easy and simple, still leaves the jig intact for use with standard 556 lowers. Be sure to remove the mag catch BEFORE using the jig otherwise you will crush things that you dont want to crush. Finish on this lower is deep black and on the shiny side. It looked so nice, i didn’t want to machine it! I old schooled it on a knee mill with dial readouts and some calipers. I coated the inside of the fire control group pocket with oven cure Teflon-moly. Turned out looking good, although in retrospect, I should have masked off the lower, blasted the inside pocket, then used the Teflon-moly… maybe next time. Aluma-Hyde, Cerakoat, or similar finish makes the inside look like a factory job and protects from some corrosion. The SS ejector is solid and easily adjusted. Mag catch is about a millimeter too sloppy IMO, but still works great and is made of aluminum, not plastic like others. Magwell is flared a lot, very nice for speedy reloads. I tried and used factory Glock, Magpul and two different Korean mags in this lower, 17 and 33rds. Only one that didn’t drop free was the Khan brand. Ejector needed to be slightly adjusted for my mags and upper, but it is made for that, so no big deal there. Overall this is a very good quality 9mm billet lower receiver, I am pleased with the fit, function and appearance. I would buy this again without hesitation.

Great quality lower. 1st glock mag lowers I had done but wasn’t for me. Buddy came over and milled it on my milling machine and I helped him assemble. He’s so happy with the end result that he said he wants to do a few more and wants to get a jig to do them at his place so he doesn’t have to drive out here. Did take a little longer to get, but that was expected. Everything is taking longer to get right now, or it’s out of stock.
We choose the 7075-T6 because it is one of the highest strength aluminum alloys available. Its strength-to-weight ratio is excellent and it is ideally used for highly stressed parts.

Threaded 1/2×28 instead of 1/2×36 to give you greater versatility when choosing a suppressor.
Integrated feed ramp and barrel extension.
Since the “barrel extension” is an integral part of the barrel, the length stated is the true overall length. For example, an 11” 9mm barrel has the same outer dimensions/length as a 10.5” 5.56 barrel.
IMPORTANT: A standard 1/2×28 flash hider will not have enough clearance for a 9mm round to pass.
Before installing a muzzle device, ensure a 9mm round will drop freely through the muzzle device bore.
You may use this barrel with a lower receiver that is a Registered SBR, Machine Gun, or Pistol. Possession of this barrel along with a Non-NFA lower receiver is Prohibited, except when installed on a Pistol configuration firearm.
