This paper aims to explore some realistic configurations of anisotropicspherical structures in the background of metric $f(R)$ gravity, where $R$ isthe Ricci scalar. The solutions obtained by Krori and Barua are used to examinethe nature of particular compact stars with three different modified gravitymodels. The behavior of material variables is analyzed through plots and thephysical viability of compact stars is investigated through energy conditions.We also discuss the behavior of different forces, equation of state parameter,measure of anisotropy and Tolman-Oppenheimer-Volkoff equation in the modelingof stellar structures. The comparison from our graphical representations mayprovide evidences for the realistic and viable $f(R)$ gravity models at boththeoretical and astrophysical scale.
