    Circular RE nut - what is the best tool for the job

    Gang - what is the highest quality tool available to remove this type of RE nut?
    (I'm looking for one with a 1/2" or 3/4' square drive so I can use one of my torque wrenches)

    Thanks in advance!

    Buy a new castle nut.
    One that can take a staking.

    Torque values on the receiver extension isn't important.
    Get it good and snug, then stake the endplate into a notch in the castle nut.

    Otherwise, if you plan on using that one instead of buying a $4 part.
    You will need a spanner wrench.

    Seriously, the correct part will cost you way less than that spanner.
    If you can find it.

    i'm sure iraqgunz or someone more knowledgeable will chime in, but personally i haven't seen any very high quality wrenches for that type of nut. they usually only have a single pin which is prone to shearing off.

    are you trying to remove it or tighten it? either way, i'd replace it with a regular castle nut with square slots - there are quite a few good tools for those. you can use a punch to loosen it, then toss it as it'll be chewed up.

    I don't think that the part is actually installed.
    The takedown pin is not there.

    Guys it's installed - I removed some parts off of the KAC lower and the RE has to go to make way for an A5 RE and associated kit from VLTOR... KAC installs their take down pin detent and spring from the grip area, and it sits 90 degrees perpendicular to the original design. I already have a Colt castle nut sitting in my pile of new parts to go on the lower, but I would still like to find a nice tool to remove and install these. KAC obviously used a nice tool to torque up the nut since it is not marred in any way and I'm sure it is on there "guten-tite."

    I have fired off an email to these folks to ensure their spanner wrench works properly with the RE nut.
    I'm still open to any version that will allow me to use a 1/2" or 3/4" drive torque wrench.

    Thanks again...

    If you don't care about the nut, you can tap it off with a center punch as MM suggested.

    Otherwise, I think finding the right size spanner wrench with a 1/2" drive on it will be difficult.

    I believe the DPMS ar-15 tool will work to take that nut off. I would just try to barrow one to get it off. Then get a Hammerhead tool if you don't already have one.

    I was looking for a way to get it off and put it back on with a torque wrench without damaging it, and add to my tool collection. Thank you 556Cliff for responding with relevant info.
