I had begun this thread previously and removed.
Having done my share of builds on stripped lowers, 80% “Glocks” and most recent RIA 1911 Kit I wanted to do an AR 80 and decided on an AR10 and then a Noreen 80 for the name, being billet and the sale price.
For a jig I decided on a Juggernaut Tactical Ultimate Jig for the option to do most any AR caliber from 9mm through .500 Auto Max
Currently I have emails in to both companies on what appear to be compatibility issues.
First I discovered I could not even assemble the jig with the lower in place, bolts were to short and a thread popped before any actual tightening began
Some abbreviated email correspondence with Juggernaut:
and I’m still emailing with them, all good.
While working it out I got 2.5" bolts and cut down .250, this snugged things up nicely.
The next thing to happen that make’s it look as though these two do not play well together is that the top plate on the jig is supposed to allow side-to-side movement for centering the pocket cuts but is maxed out, no movement at all.
But, that should mean it is centered, right?
To be able to tell I tried to thread the alignment tool through the buffer threads to check.
Well, turns out that portion of the lower was 80% also, the threads did not go all the way through.
And I have emails in on this issue also,
While working it all out I ordered a tap
and found the alignment tool still did not fully reach the lower as it’s supposed to.
plus, its NOT centered and has no room for adjusting…
I’m not sure what will happen with this particular lower but I do not plan to toss in the towel, I may simply find a more compatible lower for this jig and plan to keep this updated as it concludes.
