This applies to ARs too, so please feel free to comment on that as well, but I am specifically interested in my bolt guns.
Have QD brakes on all my rifles for various cans. I was wondering first of all if anyone noticed their group sizes opening up slightly with a brake installed vs none. Secondarily, how are you cleaning the crown? Does your brake thread onto the barrel far enough that the crown is 100% in contact with the initial baffle surface of the brake? Or is there a slight gap between the crown and the initial stage of the brake? In the case of the latter, how does one effectively clean the crown from the carbon build up that I assume would collect in the gap? Thanks. |

I normally put a few drop of CLP on the crown and let it sit while I clean everything else. In the middle I'll continue to put drops on the crown so it soaks in. When done with everything else I'll clean the crown with q-tips, or a bronze brush. Everything seems to clean up pretty well.
I haven't seen to many brakes that actually make contact with the muzzle. So most likely there's gonna be that monotonous gap to contend with on most brakes. |

Secondarily, how are you cleaning the crown? I don't. Where the crown matters is nowhere close to the threads and carbon buildup on the outside of the crown is a self-cleaning, non-problem. When you clean your barrel, the jag, brush, patch, or whatever will contact the crown where it needs it. I have had brakes cause large amounts of carbon build up "around" the crown and had no effect on accuracy. Unless you are uber anal about cleaning every nook and crevice, just shoot it and clean the barrel when accuracy falls off. Carbon will build up, but it won't get in the way of a bullet. |
