AR300M -- Software / OpenWrt?

I apologize for such a basic question, but I have not found a direct answer to it anywhere

My question is on the OpenWRT software the AR300M runs, in past routers GLI has been known to have their own UI ontop of OpenWRT.

Is the AR300M OpenWRT clean, or does it have GLI’s UI?

If it does have GLI’s UI is it possible to flash clean OpenWRT? If so where can I find the files for this?


I apologize for asking such a basic question but it is a rather big deal to me

Thank you.

There is a clean and GL version:

what version of openwrt is the clean?

OpenWrt Chaos Calmer 15.05 / LuCI 15.05-54-gfd60055 Release (git-15.363.78009-956be55)
