Hello all, Glad to be back poking about the forum for a little while, I've been extremely busy with school, work, and my new hobby.... machining!! This project all started when I saw a gap in the muzzle brake market, every brake out there had some design aspect that just didn't seem conducive to maximum recoil reduction while still being pleasant to the shooter. I already knew I would like to get into machining and gunsmithing eventually, so I figured making muzzle brakes would be a great place to start. I studied different brakes from different manufacturers and eventually compiled all my data to design a muzzle brake that had all the features I wanted, and none that I didn't. My design goals were to have THE most effective brake on the market, while also being pleasant to the shooter in regards to the concussive blast. Based on my testing, I would say I have achieved my design goals. I am making a 3 port for firearms chambered in .223 rem -.308 win (should be extremely popular with the AR-15/10 crowd), a 4 port for .284 win -.300 WinMag, and a 5 port for any of the RUM or Lapua based cartridges on up. I am still working on the cosmetic side of things, but that is a minor issue now that I have the design down. I did some recoil tests and took some slow-mo footage and put it into a short video demonstrating the recoil reduction capabilities of the Cold Boar Muzzle Brake.
