If you are modding the HS stock, the magpul short action might work, an atlas worx, ptg or badger ord. likely requires inletting. Go for aics mags. binder plate probably, assuming you just shoot factory. I have some non-binders and they jam on ammo tips sometimes.
If no modding the stock, maybe drop into one of the many aics ready stocks like mdt or krg or what have you offerings.
