back when i got my AR a few years ago, I saw the SPR/m4 and decided that was what i wanted, fast forward today time and finally saved enough money for a can. I looked on AAC's website for dealers in AK and noticed that they no longer have the suppressor on their list of 5.56 cans.... did they discontinue them? serious facepalm if they did because now i have to change my flash hider.
