Just wanted to share my work.... Sun Devil Upper w Centurion Rail Mod

Customer ran into problems when the box of new parts showed up to his doorstep and tried to put them together.

The Sun Devil Upper Receiver is thicker than normal uppers so the anti-rotation tabs on the back of the rail keep the rail from mounting properly mounting.

So I machined relief slots around the barrel nut threads on the Sun Devil Upper Receiver so the rail tabs can lock into the upper.

Afterwards, the area was touched up.

Hows this for same day 1 hour service?
