[QUOTE="Jay Kyle, post: 28966, member: 347"] The primary purpose of any muzzle break is to reduce felt recoil - understood. Having worked in the aircraft industry I also feel that little holes - or more correctly smaller total port area - will drive up the noise level as the gases escapes at a higher velocity. Low velocity = lower noise output, higher velocity = higher noise output. Important point here is total forward thrust against the body of the break is what provides the recoil reduction. Low noise is one of the primary reasons you see larger engines on the big jets (that and fuel efficency), the gases are slowed down which makes for quieter engines, but total thrust remains the same. I also compare a muzzle break to the reverse thrusters you see at the back of a 737 engine. They can be very noisy when engaged. So enough of the rambling, what makes sense to me as to what design makes an efficent brake is large total port opening - for lower noise and maximum redirection of gases for maximum forward thrust. There is one that intrigues me, the Op's unit. Any experience out there on that unit? AB [ 10-20-2003: Message edited by: AlbertaBound ] [/QUOTE]
