Wild West Guns here in Anchorage produces their own version of a muzzle break that I have looked at. It is billed as a low-noise break that reduces recoil better than other better known breaks, like Weatherby's KDF breaks (which are not low-noise!). The break produced by Wild West Guns is basically six really big holes instead of a bunch of smaller holes at the end of the muzzle. I've never tried one... I use Weatherby's KDF breaks, which work great...I just protect my ears. You would think that if they were quiet and reduced recoil they would sell like hotcakes. Here is a link to Wild West Guns: www.wildwestguns.com Look under accessories.

The one that supposedly doesn't increase noise levels and allows you to observe hits because the muzzle would dip...

What happened to those? I haven't heard anything in months..

Do they work er what?

I was very interested in them, and still am...

I believe you are thinking about BP Technologies at www.bp-tec.com

I have been thinking about these guys for a while, and might have them work on a MB for my 550 Mag project rifle. Reduced recoil, limited or nil muzzle rise with no increase of noise? Sounds great but I'll believe it when I experience it.

Interesting,
The physics as explained aren't too unreasonable.
Video cameras automatically gain down the sound, and you can light load any round to a certain extent. Maybe I'll get one and try it on my 375 WBY when I get it paid for (Sam, the first check is on the way).

Anyone try it or measured decibel levels with and without it from the shooter's placement?
