I have an older Kac lower and the buffer retainer doesn’t have enough coverage so I need to give it one more spin but I can’t get the dimples castle nut off. People recommend the brownells tool but they seem to be forever out of stock. Anyone else know a good tool to get it off?

Look into a Williams Adjustable Pin Spanner Wrench.

I also am interested in locating a tool. Hoping to find one with ability to properly mate to torque wrench

This is what I use, Tapco, basically what JohnnyUtah427 uses. I modified the pin to fit better, made it slightly smaller diameter for a better fit and shorter so that it didn't bottom out early, so that the castle nut now fits the entire radius of the tool. ETA: forget the torque wrench, just tighten it up snug as possible

I had an older DPMS wrench and the pin sheared off. I bought the Brownells tool and have been using that. I also bought a $330 jig to hold the lower in place when tightening castle nuts. Expensive, but everything stays in alignment now. They’re only produced in small batches, so snag one when you can.

Lower Jig VISM makes a lower receiver block that does the same thing for much less |

KAC uses the brownell tool. The fact you can attach a 1/2" torque wrench to the tool that applies properly radiused torque makes it better than anything else available. It's in and out of stock often.
Similar tools that utilize a dynamic jaw are particularly bad because they move, slip, and damage components of both the tool and the work. https://www.brownells.com/tools-cleaning/gun-tools/rifle-tools/ar-15m16m4-buttstock-tool/ https://www.brownells.com/tools-cleaning/gun-tools/rifle-tools/ar-15m16m4-replacement-pins-for-brownells-buttstock-tool/ |
