baldie Posted August 13, 2020 Report Share Posted August 13, 2020 Just had a large batch of these made. Following on from the success of my 3 port brake, I decided to design a bigger unit, and one that can also be self timed by the user. [ the 3 port has to be timed ] After playing around with several american brakes, I had the base design sorted, and then started making alterations by experiment. My brake has different port angles to most, as i've tried prototypes. Some could be felt by the shooter, which is not good. This brake puts the shooter in what is effectively a triangle of calm. It also has [like the 3 port ] active gas divergers inside the port. Rather than rely on the gas finding its own way out , as other brakes do, this slices the gas in two, and forces it out. It can actually be seen when viewing shots from the side. The baffle angles also influence the noise. This brake doesn't sound noisy compared to the vast majority out there. I toyed with the idea of top ports, but that can influence , not for the better sometimes. Testing this brake on a 6XC and a .224 valkyrie this week, at 300 yards, the valkyrie's crosshairs never left the bull on an electronic target, which was quite amazing to witness. The gun just recoiled in a straight line backwards, and was similar to a spring airgun in recoil. I have a batch in 18mm x 1 and a batch unthreaded to accommodate anything. The brake has a rear nut which is left hand threaded. You screw the nut up closed, then spin the brake down to the shoulder. Reset the brake square, then back the nut off, to butt against the shoulder. Spanner flats on both the nut, and brake body to achieve this.

lapua Posted August 13, 2020 Report Share Posted August 13, 2020 Dave, can you bring an 18mmx1 to orion, i’d like a closer look and possibly purchase. Gary Quote Link to comment Share on other sites More sharing options...
baldie Posted August 14, 2020 Author Report Share Posted August 14, 2020 Sure Gary, what calibre is it for ? Quote Link to comment Share on other sites More sharing options...

lapua Posted August 17, 2020 Report Share Posted August 17, 2020 Awesome brake, moved my poi 0.3 mil down and groups not affected. Rifle shoots same poi moderated and unmoderated, and 0.3 mil low with brake, so all manageable within the extra bit below zero on the mk2 Very pleased with this. Cheers Dave Quote Link to comment Share on other sites More sharing options...

KatoomDownUnder Posted October 9, 2020 Report Share Posted October 9, 2020 Nice work Baldie, very nice indeed. If I can find it, I've got an old engineering paper at work on Muzzle Brake construction and effectiveness. Although it's based upon larger calibres (105mm) if I can find it I'll pass it on as it's quite interesting reading. Quote Link to comment Share on other sites More sharing options...
