Hello, I am new to this type of weapon. I have many types of firearms and have been collecting and shooting for years. I don't have a California-legal AR-type .223 to varmint hunt. I have been reading about the Stag M6 super varminter and it interests me. I went to the local gun store and they offered me the Sig 556 DMR. The DMR costs twice as much as the Stag M6 varminter. The M6 boast 1/2 "MOA. The gun store clerk swears that the Sig is the greatest AR-type varminter ever. Please give me your opinions. I own assault weapons such as the H&K 93 and Belgian FN FAL from years ago....but, I don't know about the newer brands and models. I live in California. I am a 57 yr. old dentist that likes to buy toys to turn me on.
