I recently purchased an EDgun R5M rifle and noted my barrel was out of alignment. This was documented here:

Several other folks responded they had seen the same thing with their rifles. I'm terrible at eyeballing alignment so I put together a simple procedure that should get the alignment close to perfect. Here's how I did it.

Several other folks responded they had seen the same thing with their rifles. I'm terrible at eyeballing alignment so I put together a simple procedure that should get the alignment close to perfect. Here's how I did it.
- Get two 5.5mm small pieces of drill stock. I ordered mine from McMaster-Carr (https://www.mcmaster.com/catalog/2900A322) for roughly $4.50 each.
- Loosen the barrel nut
- Insert the drill stock into the two hole in the barrel nut rest.
- Level the rifle using the scope rail.
- Place the level on the drill stock and twist the rest until both level measurement places are in alignment.
- Hand tighten the barrel nut slightly and verify both level measurement have not shifted.
- Put a piece of tape on both the rest and the barrel shroud. Draw a witness mark to verify the rest does not shift during torque down.
- Torque the barrel to 12 foot lbs per zx10wall.

You can see from my original post that my barrel was out of alignment by 17 degrees. Hopefully, this procedure is useful to others.
