New Noveske NSR rail!

[Hmac]

My barrel nut would NOT index correctly, waiting a new one from Noveske. Should be here today, excited for that!

Decided that the giessele reaction rod would be a really great tool to have and I want one!

My barrel nut did index OK, but it took every bit of 80 ft-lbs (and maybe a hair more) to get it there. The reaction rod took a lot of the anxiety out of that process for me.

Out of my 4 NSRs so far, all have indexed fine. 3 I had to switch to the 'other' side of the nut (thank freakin' goodness John thought to give us two options to time it) but all worked great.
I tend to like barrel nuts on the tighter side, so I'm accustomed to getting a foot into it. Always with the moly grease, 4 tighten/loosen routines.

Just about perfection on the design IMO. Maybe a titanium nut would've been perfection?

My BBL nut wouldn't index right either side so my gunsmith lathed it out a bit and the worked fine.

I have put 2 NSR's on and haven't had a problem indexing. I did have to swap to the other side but, that was it. I wonder why so many are having issues.

Honestly not sure!!!

But I got my second nut in today and that one STILL doesn't work! So.... I'm definitely not going to make it to 3-gun tonight! I think with this second nut I could force it by going to over 80lbs toque, but no thanks! I'm already not super-happy with this upper as it's showing NOTICEABLE flex at 80lbs.

I'm sending Noveske all my parts and they're going to look at it for me. They've been really helpful so far. I'm sure mine is the fluke (my luck!)

you've now successfully troubleshot out that it's your upper then

[Aaron_B]

Yeah definitely wouldn't go over 80. That's crazy 2 different nuts not working. I guess it could be a possibility of you upper being out of spec but idk. Good luck with getting everything straightened out.

I have installed 3 NSR's and all three required going just a hair over 80ft lbs.

Yes. The reaction rod allows cranking hard on the barrel nut without having to watch that troublesome receiver deformation.

Mine is indexing just fine, but I'm having trouble getting it lined up just right w/ my Vltor upper receiver. It's very close, but just a hair off...
