This is a fully personal thing, but you might want to maybe look at Magpul, BCM, B5, Reptilia, DD, Ergo, just a military M16A1 pistol grip or.. maybe anything else at all before FAB. Their stuff looks like it was designed by a child for nerf blasters or a supersoaker; though obviously if you want that civvie aesthetic vs a military type rifle then hey have at it.
