Love Nathan's brakes. They put the "B" in brakeNathan from Muzzle Brakes and More
I'd go with kenn
As @NW Hunter noted, Nathan of https://muzzlebrakesandmore.com/muzzle-brakes id from Boise, ID. I have a few of his MBs that work like a champ.There has been a member on this forum that manufactures muzzle brakes. I believe he is from southern Idaho. Any help? MTG
I probably got one of the last Ross Schuler brakes before Kelly took it over. Kelly now offers the self-timing version. They are very reasonably priced and are effective for what it is designed. However, I prefer Nathan's MBM brakes.This is probably the member the OP was referencing. I have used Kelly's brakes and I like them and they are affordable.
Ross Brakes
I have a MBM brake and like it, haven't tried the SRS brakes yet.
