The AR’s original A2 fixed stock worked well, but there are times when other stocks are better. In Part I, we cover five models from Ace Ltd., Boyds’, FAB Defense, Hogue, and LaRue Tactical. In Parts II and III, we look at units from BCM, Daniel Defense, Law Tactical, Vltor, Ergo, Luth-AR, Magpul, TacStar, and Mission First Tactical.
