Basically just get the upper to me with the device you want pinned and welded (or order a muzzle device through me) and I will P&W for free. The $20 shipping charge covers the label, box, and packing back to you.
*** Please write your name, address, muzzle device, barrel length and any other pertinent information on a note and place it in the box so your upper does not get confused for another***

The P&W process is not always the prettiest or cleanest on a muzzle device. The are done to satisfy the ATF's 16" minimum requirement for rifle barrels.
