think he means, people that go all out and "Mall ninja" their gun. my rifle came with a full free float rail, and magpul moe stock. ive added an moe + grip, (a2 is pitiful), and some better rail covers. these items are fully functional and dont just make the gun look "cool" in my honest opinion. sights are a must though, as mine is full flat top. mbus was the more economical choice. they work, they cost less then full steel ones. perfect day!!
