    I have been using the Hammerhead here in country since I picked it up at SHOT. I like it. I even grabbed some for a couple associates of mine.

    I'm tired of marred castle nuts and scracthed buffer tubes and am looking for a new wrench.

    How does the Hammerhead tool fit into *most* extension nuts? My current wrench only has three lugs and it seems the main problem is that its lugs are too narrow to interface properly with the corresponding grooves in most available castle nuts. This poor fit allows the wrench to slide around when force is applied. This will invariably result in a marred nut and an occassional scratched tube.

    The tool isn't laying flat in this pic, but there are four solid point of contact made.

    This one I've used at least a 1/2 dozen times and it holds up fine.
