I am looking to get a suppressor for my 5.56 gun. I just want a entry level fairy inexpensive can. I have been looking at the AAC M4-2000 and the AAC 5.56 SD. Anyone have any other suggestions for a entry level can? Or have any thoughts on these two cans? I am also interested in Silencerco cans but haven't found any budget cans that they make.
