Talked to the manufacturer, disregard thread.

Next time, remove the clothes before you proceed with the pounding.
This will significantly reduce the damage to your tool.

LOL shhhhhhhhhh!

By the way, never thanked you for the great job you did on that last upper.

I took it to the range to zero the irons and that Centurion Arms barrel is one of the most accurate chrome lined barrels I have ever shot.

I would have loved to have kept that thing, but it was a gift - I'm going to start buying parts to build a similar upper with the same barrel and I'll let you know when I have everything.
