Good luck with this one! - Aero Precision AR-15 BAR Barrel Nut and Shims

Anyone considering buying one of these barrel nuts... BE WARNED!!! This will not be able to be installed with any armorers tool that I have found with the exception of the Tapco Intrafuse wrench! They can say you can use a standard milspec wrench, but it's ac dirty lie! This is a well known problem online once you start trying to figure out why all your milspec armorers tools won't work on it. They're a little fussy about getting the hole in the proper position to fit the gas tube through, but that's the least of the problems. Also, the Tapco wrench that works for this nut is now not available because they've been discontinued or "out of stock", and since they're discontinued, probably always will be. Also, the holes the wrench goes in are way too close to the edge of the nut so be very careful when torque is set. Great idea, horrible execution with this model barrel nut...
