I am certain it will work. The AR15 rear sights are a little taller but the front sight on the HP carbine adj up and down. The AR15 sight being more compact would open up rail mounting space for more RD sight options and because it's taller it would be easier to find a Rd sights that would Co-Witness with it.
MagPul has a new polymer AR fold down rear sight out. They run about $60
UTG makes good lower cost metal sight & one that folds. They run about $30.
