Which Open Castle Nut Wrench?

[titsonritz]

I knew better and I bought a POS anyway because I already have a Magpul armorers wrench and figured to only use it once or twice where a closed style would not work. It's not going to cut it. What do you guys recommend for an open or spanner style Castle Nut Wrench?

This is the hunk of crap I got.

I've been using the wrench that comes with KMR rails for the castle nut for years.

^ That. When I sold my KMR I took money off the price so I could keep it and use it as a castle nut wrench.

BCM wrench is what I use. Sturdy, inexpensive, small, simple, and also works on KMR barrel nuts: https://www.bravocompanyusa.com/BCM-...cm-kmr-bnw.htm

Thanks everyone, I forgot the KMR wrench doubles as a castle nut wrench. I'm on it.

Out of curiosity why wont the magpul wrench work? I thought it was designed to slip over both rifle and carbine extensions.

It is and does well, but not necessarily with pistol extensions and in the case of a Vltor A5 RE there is a raised ring that will not allow a closed designed wrench such as the Magpul or Hammer Head to pass over it to allow access to the castle nut, thus the need for an open style. That KMR wrench is just the ticket and I still can't believe I allowed myself to buy that POS I bought from a LGD, I got in a hurry and didn't think things through. At least it was a cheap booboo.
