Ever have a build where you think you have everything at hand and you will be able to hit the range tomorrow? That’s where I was 3 weeks ago.

But then I needed to order a Griffin fixed barrel spacer to direct thread my Rev9 on the 8” AR9 barrel. Then I saw that with the 9” Aero enhanced Gen2 rail I could tuck the can inside for more grip space than the 7” I had. It uses a BAR barrel nut and the instructions say “standard AR15 armorer’s wrench“ so between my Magpul, and cheap Tapco I’m all set, right? Not so fast bucko. It’s needs the 3 round hole nut end type. The Magpul has 3 square pegs that don’t line up anyway and the Tapco has no pegs at all.

So what are you using for the BAR nut? Aim sports has a wrench with the three round pegs, but on close up it looks like really cheap construction. And one of the pegs was shorter than the others and rounded off. If the MN Twins hadn’t just made the post-season I’d be grrring.
