i also have a spec war , use it on 223, 204 22-250 and 308 so far, oh yeah put it on my 22-45 pistol all you here is the action noise.... on the rifles it is so quiet . im gonna get one just for 22 and 17hmr very soon. you will like the spec war but it is heavy, on shorter length rifles it doesn't bother me , and its rated up to my 300 ultra mag but I have wrong threads on 300 right now... good luck on whatever you buy!!!
