Well my new Aero handguard arrived at the house and this was the last piece of the puzzle needed to put together my 6.8. I got out my Magpul do all super mega wrench and discovered it won't work on the Aero barrel nut so looks like I'm gonna be looking for a new wrench. How do they measure barrel nut hole spacing is it center to center or outside to outside? The Aero nut is 1/3/4" on the outside and around 1/9/16" on the center , most sellers of these wrench's do not list the dimensions of them, I think it was Right to bare Arms listed the Mcstar wrench at 1/3/4" for the barrel nut end it looks like this is the one I need what do you guys think? Anyone have experience with the Aero handguard barrel nut I don't want to buy another wrench that won't work for this application? Thanks for any help you can provide.

Any of the three prong style barrel nut wrenches should fit. If you buy the M4E1 upper it comes with a barrel nut wrench which is different than the BAR nut that you use if putting the handguard on a standard upper.

Thanks for your reply's guys . Crayj I have a regular ole garden variety Aero upper not enhanced and I do believe it is called a Bar nut and it didn't come with a wrench, thanks again.
