worth it or waste of money?
It is in almost every AR15 that I own, and it can be amazingly accurate (if the whole package is assembled carefully). Other than that, you don't need to worry about the difference between .223 and 5.56....worth it or waste of money?
How much is the waste?Waste of money if your shooting bullets less then 55 gr.
That sounds illegal.used it in my bolt guns when i was shooting 223 palma and fullbore rifle..
