WTS a complete AR9 upper receiver, but in parts. I collected these and just never got around to putting them together. I hand-tight assembled them to mock it up and paired it up with a lower and did a regular function check, worked great - did not actually shoot anything through, however. I then took it apart again for storage purposes and just never got around to it, as i have another ar9 setup. you will need a lower and a regular carbine spring, and this kit will be GTG.

If you do not have an upper jig, I can assemble it for you, just let me know. yes I have the grease and torque wrench and all.

I'd like $300 PPFF please.
