Midwest Industries Upper Receiver Rod (MI-URR)

So, just to clarify, is the torque hitting the charging handle slot, or the hardened locking lugs?

I like this design, but not sure where the pressure is really supposed to be applied.

My biggest concern, of course, would be busting an extension, anyways, because it's not fully "locked in".

It looks like those slot exist for the lugs, but they don't seem as deeply cut/prominent as the others.

Grea job guys, you really continue to push the envelope with new tool designs.

Both, just like the Windham Weaponry barreling jig and the 2UnqueLLC barreling jig. This type of design keeps your indexing pin from shearing and your sights in alignment while tightening or loosening a barrel nut. Unlike the standard reaction rod style tools.
