Recomendations for castle nut wrench and ASAP

hey everyone,
I’ve got my lower receiver assembled with the Magpul ASAP but, the castle nut wrench I’m using is a pain because the rail section of the ASAP is in the way and my wrench keeps slipping off.

Anyone out there could recommend a good castle nut wrench that will work around the ASAP rail without slipping off?

I’ve done a search but haven’t found anything

Thanks guys

I’m not sure what wrench you’re using but mine was a $7 wrench from Brownells and I had no problem using it to install my ASAP.

I used a RRA CAR stock wrench and it worked fine.

Thanks for the tip guys!

I just used the Spikes Tactical wrench with my own ASAP installed, and it worked fine. I suppose it depends on how the threads and notches go, though. If the notches had been more to either side, there might have been a problem.
