    Fits good but will it last?

    I needed this tool to remove and install a barrel nut. It fits the barrel nut and the castle nut very well with little to no wiggle. My only knock on this part is that the metal seems a little thin around where it attaches to the ratchet. Only time will tell if it holds up well.

    Perfect for its intended use

    Excellent tool, fits on any standard torque wrench with a 3/8 drive, and works on both the KMR Barrel Nut and the Castle Nut (which is actually why I bought it). BCM quality, well worth the $7 or so that it cost.
