Epc-9 8.3in 9mm enhanced complete upper receiver with flash hider - Aero Precision EPC-9 8.3in 9mm Enhanced Complete Upper Receiver with Flash Hider

I have to thank Optics Planet for making my AR9 build affordable. This was the item that I really needed most after deciding the barrel length that I wanted. OP coupon deals really came through for me and I now have a really stout, reliable, and fun AR9 to shoot. Aero Precision does this one right with their second gen barrel - revised cone feed angle. I used their EPC9 BCG and their EPC9 7.7oz buffer, and I have over 500 rounds through this unit. Hasn't failed me! I like it! Thanks again OP and AP.
