Just bought a Rock River Arms A2 Carbine, and am planning on heading to range this Weds. Question: Do I want to break the barrel in? I know some gun manufacturers say you do and some say you don't. If the answer is "yes", how do I go about it?

Go shoot 300 rounds, then clean it.

I have a RRA CAR A4 that I picked up in June as a birthday present to yours truly.  (When you get to be in your 20s, the 'rents buy you stuff for the apartment, which is useful, but not real fun...)

I called RRA to find out about the break in idea, since supposedly some barrels need it, and was told by an armorer there that the barrels are ready to rock right out of the box.  I promptly took it out shooting, and it's way more accurate than I am.  

In short, RRA sez to go out and have a good time.  [Baron

Quoted: just shoot it

When I got my NM RRA, the guys at Rock River said to fire three shots and then clean it. Once you have fired 15 shots it will be broken in(so they told me)
