.308 DPMS SASS Barrel – Muzzle Threads Removed and Barrel Crowned

I recently came upon a good deal on a DPMS 7.62 SASS Teflon Coated, Fluted Barrel. The problem is I cant have a threaded muzzle in my home state so the threads needed to go.

Rather than send the barrel out to a gunsmith I decided to machine it myself in the lathe at my day job. It was pretty easy and I think it turned out well.

Here’s what I did.

  1. I wrapped the barrel with a precision shim stock perfectly for nearly 360 degrees. This was done to protect the teflon finish from the lathe jaws.
  2. Then I placed the barrel in a 4 jaw chuck. I used the 4 jaw because its the easiest way to get the bore centered.
  3. I indicated the bore and adjusted the chuck until the bore was rotating perfectly centered.
  4. Next step was to remove the threads from the muzzle
  5. After removing the threads I adjusted the tool holder to give me the 11 degree crown.
  6. Cut the crown to a mirror finish

I have read that a brass ball with lapping compound  is typically used to fine hone where the crown meets the bore. I decided to skip this step for now just to see if it matters.
