The simple CSR brake from by Center Shot Rifles is the one I use the most of. It is very effective. The only one that works any better is the Holland Radial QD brake. No need to ship your whole rifle. Just make an index mark at 6 oclock to let us know which way goes straight down for timing.
"Only accurate rifles are interesting".
Advantage is weight, out on the end of a 26" barrel a few ozs. in a game of trying to save ozs. could be important. Maybe balance the rifle a little better, or maybe not effect the barrel vibrations as much as a heavvier one. 30 degree slanted ports with about braking surface as I can get in a small brake weighing .82 oz for the 3/4" brake.
