Very difficult to install - Strike Industries Multi-Function End Plate / Anti-Rotation Castle Nut

I had a very difficult time installing this end plate. I've built 3 AR's entirely and I'll never use this end plate again. Yes, it is multi functional, but what a pain in the @$$ it was to install. I generally love SI products, but this one isn't it. I've bent one too many springs trying to get this endplate in. Do not recommend.
