Did you get the other jig yet?
What are your thoughts? Pics?
I received the JC Machine and Motorsports jig at least a couple of weeks ago. I haven't used it yet but I did test fit a few barrels into an upper to test the fit of the jig.
I noted that barrel extension portion that engages the locking lugs seems to fit better, with less play than my Geissele Supper Reaction Rod. Also, (as far as I can tell) the upper bottoms out on the charging handle slot support at the same time that the locking lugs bottom out on the barrel extension engagement portion of the jig, which should be great for keeping the rear sight aligned with the front sight and completely eliminating any possible chance of shearing the indexing pin in half.
It's a pretty hefty tool and probably weighs around 5 pounds. It looks exactly the same as it does in MAC's Windham Weaponry factory tour video, it has no finish so you do need to make sure to keep it oiled up.
I will keep you guys updated with any new info as I get it.
Sorry, no pictures... I don't have a camera, or even a very good phone for that matter... I know I suck.
