stre-tch Posted November 17, 2013 Share Posted November 17, 2013 2 questions. Could you install it on an upper with the gas block under the handguard (i.e. is it a system where the tube goes on after the gas block)? What is the ID of the tube?

californiasushi Posted November 17, 2013 Share Posted November 17, 2013 You can with the standard NC-1 free float tube. I'm pretty sure you can't with the small diameter free float tube but not 100% sure. It looks to be a little over 1.8" ID. Link to comment Share on other sites More sharing options...
stre-tch Posted November 18, 2013 Author Share Posted November 18, 2013 Perfect thanks! Does it have a steel barrel nut? Link to comment Share on other sites More sharing options...
ac4wordplay Posted November 18, 2013 Share Posted November 18, 2013 ...(i.e. is it a system where the tube goes on after the gas block)?... Barrel nut gets installed first, then the gas block and tube, then the FF tube. I'll check ID when I get a chance. Link to comment Share on other sites More sharing options...
mic2377 Posted November 19, 2013 Share Posted November 19, 2013 I have one and it fits over a lo-pro gas block with ease, in the pistol position. It is an aluminum barrel nut. I seem to recall the ID was in the 1.75-1.8" range. Link to comment Share on other sites More sharing options...
atvman400 Posted November 21, 2013 Share Posted November 21, 2013 I just installed one of these this fall to replace a shorter hand guard and found that I had to drill and tap some holes for set screws because I couldn't get the hand guard to keep from rotating with just the jam nut. Anyone else have this problem? Link to comment Share on other sites More sharing options...
Dan Sierpina Posted November 21, 2013 Share Posted November 21, 2013 I just installed one of these this fall to replace a shorter hand guard and found that I had to drill and tap some holes for set screws because I couldn't get the hand guard to keep from rotating with just the jam nut. Anyone else have this problem? Did you get a proper spanner wrench for the nut? Yankee Hill Machine has one that works extremely well. I think the lock nuts are the same between those brands, or at least close to the same. Link to comment Share on other sites More sharing options...
atvman400 Posted November 26, 2013 Share Posted November 26, 2013 I had one that was very close from the shock on my snowmobile. I held the tube in place with a strap wrench and cranked on the locknut. I gave up when it came loose the second time and drilled and taped into the barrel nut. No problem now.

Shooter115 Posted November 26, 2013 Share Posted November 26, 2013 Interesting. I have four of the Nordic HG's mounted and I've never had one come loose. Best buy in the market IMHO. I've got 3 builds in the works now and pretty sure they will all be wearing NC hand guards. I have broke a lock ring before, but it's my own fault for not having the proper spanner wrench. It's also worth mentioning that the one that broke had been installed and removed several times. When it broke one phone call to Nordic had a new one in my hands in a couple days.
