I have a previous world record holder in 600 yard and 1,000 yard benchrest competition in the next room. I asked him if he 'needed' a break as you requested and his response to me was:
"Hell no I don't need a damn muzzle break on my (competition)gun, it shoots better without it and I don't need all that extra noise around my shooting area".
For the record he has a custom built 6.5 x .284 bolt gun on a completely tuned, bedded, fine tuned, re-tuned and custom tuned action with every possible custom part you can imagine. But no muzzle break.
Your gun is beautiful the way it is it doesn't "need" a muzzle break - but personal choice is another matter all together.
Hey Quentin - I am back for a bit before the next phone conference. Wanted to talk AR's so I thought I would drop by....
