Or get a can from the several manufacturers that make AUG mounts.

My own experience is with Surefire's SOCOM family of cans and the flash hider mount. POI with either the 556RC2 or 300SPS I have used with my AUG is within the same acceptable range as with anything else. Perhaps within 1-4 MOA, depending on ammo choices (biggest variance is with M193 and cheap commercial 55gr blasting ammo, smallest with Speer Gold Dots, and virtually no shift with MK318 Mod 0). The Surefire mount is threaded for the AUG, so there's no need for a thread adapter.
Since we are all married to our cans now in the post 41F world, a good machinist could possibly re-thread your mount or bore it out and make a threaded sleeve adapter. Others have had their barrel re-threaded to 1/2X28 as another option. I would have opted for this choice if there wasn't a Surefire mount.
