I just Got a Daniel Defense M4V5 LW. I want to put a suppressor on it. I have never owned a suppressor and don't know a whole lot about them. I have 2 M4's the other being A S&W M&P M4. I would like to use it on both. My Smith has a 1/9 twist to the DD's 1/7, I don't know if that matters. I also have a bull barrel DPMS 308 that I would like to use it with if I could. I will be satisfied with just the DD M4 if thats the way it has to be. Info and options from you guys in the know please. Thanks Wanna kill these ads? We can help!
