I am looking for a collet nut wrench to remove the nuts on a rifle of mine. I know nothing about machining or what size this nut would be, so I was hoping someone here would know where I could find one, since the manufacturer doesnt offer it for sale. The outside diameter of the nut is 30mm and the diameter in-between the key slots is 27mm. From what i've seen online, it would need a wrench slightly bigger than a ER-16-E wrench. Thanks a lot, and sorry for being a noob.

Unfortunately Brownells/MidwayUSA/etc do not sell the wrench. I all ready have the other tools I need, such as a barrel vise, headspace gauges, etc. The nuts look like this, have 6 key slots in them, and have a 30mm OD, and 27mm in between the slots


There are two slightly larger nuts on the rifle for the quad rail and gas block which I do have a wrench for. The wrench I do have is similar to a safety/E style collet nut wrench.
