We construct a moduli space $Y^{mu, au}$ of Kisin modules with tame descent datum $ au$ and with fixed $p$-adic Hodge type $leq mu$, for some finite extension $K/mathbb{Q}_p$. We show that this space is smoothly equivalent to the local model for $mathrm{Res}_{K/mathbb{Q}_p} mathrm{GL}_n$, cocharacter ${ mu }$, and parahoric level structure. We use this to construct the analogue of Kottwitz-Rapoport strata on the special fiber $Y^{mu, au}$ indexed by the $mu$-admissible set. We also relate $Y^{mu, au}$ to potentially crystalline Galois deformation rings.
