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.
