Help: Stag10 barrel nut very tight going on

[stevendorazio]

I just got my X1 handgaurd from Maple Ridge Armoury, as I begin to thread on the barrel nut it turns about 1 1/4 of a revolution and then gets very tight. The upper is new and has never had a barrel installed onto it. I am new to building AR platforms and I am worried about stripping either the nut or the upper. I have tried lubricating the threads but it does not help.
Any advice or help would be fantastic, thanks.

Best advice I can give is don't buy maple ridge armory. Do not force it and ruin your upper! I'd be emailing them and telling them to send one that hopefully works...

I just got my MRA X1 handgaurd from Maple Ridge Armoury, as I begin to thread on the barrel nut it turns about 1 1/4 of a revolution and then gets very tight. The upper is new and has never had a barrel installed onto it. I am new to building AR platforms and I am worried about stripping either the nut or the upper.

Probably out of specs as I doubt STAG is the problem... RETURN your barrel nut to MRA asap.

Almost sounds like it is Armalite thread pitch not DPMS.

After a closer look, it appears the thread pitch on the nut is more fine than the stag. Does anyone know if the BCL102 has fine threads? If that's the case I was maybe shipped the wrong nut.

I think DPMS and Armalite are different barrel nut thread pitch....

 

[sky52]

Dpms is 16 tpi. Armalite is 18tpi.

I heard bcl runs its own thread pitch only the mk7 runs the dpms thread

I had zero issues installing an MRA barrel and X1 handguard on the stag-10
sounds like they sent you the wrong barrel nut.

x2 with the wrong nut...let us know their response and what the reason/s are in the end!!!

Turns out I was shipped the BCL102 barrel nut. They're sending out the right one today.

Glad to hear you got a resolution

Glad I came across this. It appears I have the exact same problem. Glad I didn't try to keep feeding on it when it got stuck.

I guess I wait for MRA to send me a proper barrel nut...

Good stuff, in any case never force it.
Unfortunately MRA also had a batch of unproperly threaded brakes, ask me how I know...
