It depends more on what kind of magazines your rifle uses. For example, I have a VSR10 and I find that pistol magazine pouches are the best for VSR mags, so I don't even need a chest rig because all my rifle and pistol mags will fit nicely on a belt. Sometimes, I use a MP9 SMG instead of a pistol, then I use a chest rig for MP9 mags and still keep my VSR mags on my belt.
