They don't make an AR mag shorter than a 10 round because it won't work with the AR magazine chute. 5 round are 10 round bodies with long springs or internal blocking.
It was a dumb mistake by Ruger to use the AR mags in the 223 and 350.
They could have easily made a very compact 5 round magazine that would have looked and functioned well. But, they didn't.
