DEF Lock Spanner TL31 with Double Sides (Single Hook and Three-Hook End)

did what it advertised that it can do.

Did a search for a ar wrench. This was among the very few that came up. This is not for a ar, but since this company paid to sponsor it. When I did a search on anything ar the wrench was in the results, even for a buffer tube wrap. Waste of time and money

Does not fit AR waste of money it does advertise that it does fit an AR, which does not.

fixed my brakes nicely

The teeth were too big for the lock ring crankcase so I was unable to use it. My bike is an 80's model Univega 3 lock ring crank lock so I'm not sure if that is the problem but it looks like it's standard. I don't understand why the teeth are so big on this tool but can't use it on my bike. I had to use my vice grip locks to adjust the lock.
