The third choice you will need to make is materials: your three basic choices are 416 stainless steel, high carbon steel, or 7075 aircraft aluminum. A snug fit means less opportunity for the brake to shoot itself off. In large part, this is due to the fact that Jeff will custom fit the diameter of your brake to match your barrelвЂ™s exact size. However, Grizzly GunworkвЂ™s muzzle brakes are a step or two above the average. Based on my internet research, it seems thatВ many shooters have had bad luck with clamp-on brakes: the вЂnet abounds with stories of them sailing downrange unexpectedly. The second choice whether you want a threaded or clamp-on brake (Threaded version of Defcon-1 shown at top left clamp-on version at top right). MoreВ info on the other threeВ can be found on his website. I chose two, the Defcon-1 and the Ghost Protocol. Jeff makes five different styles of brakes for rifles and shotguns, each serving a slightly different function. If you need a muzzle brake, one of the first choices you will need to make is which style to get. In fact, Grizzly Gunworks is growing so much that Jeff will be moving into a new facility in 2015. Grizzly caters to many military, SWAT, private security and civilian customers. Since that time, Grizzly Gunworks has been outfitting police organizations across the USA and Canada with custom-fit muzzle brakes and scope rings. By 2010, however, the demand for his muzzle brakes and scope rings began to outweigh his capacity for output, especially since he still had a вЂњday job.вЂќ So he did what so many of us wish we could do and quit the day job. At that time, he was mainly building competition rifles. To scratch his machining itch, Jeff started Grizzly Gunworks in 2008 вЂ“ mostlyВ as a hobby.

But his real loves, machining and guns, never left him. He moved up a management position in his company in 2004. Jeff became a certified tool and die maker in 1994, and got his start designing, building, and installing robotics and automation equipment in the вЂњbig 3вЂќ car plants in north America from 1994 to 2004. He designs his custom muzzle brakes and accessories with competition and combat in mind, focusing on precision, quality, and performance. JeffвЂ™s a competition shooter, and has won the Ontario Rifle AssociationвЂ™s (ORA) Precision Rifle Matches in 2009, 2010, and 2011. The name вЂњgrizzlyвЂќ comes from JeffвЂ™s 15 year old German Sheppard, who is the shop mascot. His small shop is based out of Hamilton, Ontario, which is about an hour south west of Toronto. My latest find, Grizzly Gunworks, Ltd., is the vision of Jeff Cox, a 39-year old married father of twin five year old girls. As TTAG readers may know, I love discovering and buying products made by small вЂњmom-and popвЂќ shops.
