Lower Features

The JT-9 Lower Receiver in 80% completed form. The JT-9 is precision CNC-machined from solid aerospace billet aluminum. It is not a cheap forging. This is a top-tier AR-9 lower receiver perfect for any high quality AR-9 build. Some of the features we include are last round hold open, ambidextrous bolt release, internal magazine lock (CA only), and steel magazine stop. If you are in California, please choose the California Compliant option. This comes with an internal magazine lock and our Hellfighter rear pin assembly. IF YOU CHOOSE THE CALIFORNIA COMPLIANT OPTION, THIS LOWER IS ONLY COMPATIBLE WITH OUR UPPER DUE TO THE INTERNAL MAGAZINE LOCK FUNCTION. FOR ALL OTHER RESIDENTS, THIS LOWER WILL FIT ANY OTHER STANDARD AR-9 UPPERS.
 
Because of our AR-9 design, we were able to keep all of the mil-spec dimensions from the AR-15. This will allow you to use almost any jig compatible for AR15 to complete the JT-9.

If you would like to finish your JT-9 80% Lower at home, we offer a jig-kit here. Because 80% Lowers are not considered firearms by ATF, we can ship them right to your front door with no FFL required... but finished rifles must meet all applicable laws and you must be able to legally own a firearm. Compliance with all laws is YOUR responsibility.

Note: This item is restricted from shipping to New Jersey, New York, Hawaii, Connecticut, Rhode Island, Washington D.C., Maryland, Illinois, California, Washington, and Denver Colorado.

Note: Due to ATF final rule 2021R-05F (more info here), you cannot order an 80% Lower and jig-related products at the same time. If you have both in your cart, you will not be able to complete the checkout process.

High quality

High quality receivers. It had a tight enough fit where I didn't need to use the tensioning screw.

Excellent Quality

Absolutely no wobble between upper and lower. Cerakote coating is clean. Easily the best 80% on the market atm.

Love it

Fit and finish are awesome! I could have gotten parts faster elsewhere, but worth the wait and I will wait again when I decide to build another. Worth the wait for the quality, look, and function.

9mm combo upper lower

Extremely tight, actually too tight fitting. You must hammer the take down pins to remove them. To put them in you must use an extreme amount of pressure.
