Curtis Werries, a police sniper and competition shooter, developed the Big Chubby so he could recover quickly from recoil. The idea of a completely new design originated after attending a three-week Marine Corps Urban Sniper School. Many of the drills he fired required fast follow-up shots. The popular brake he was using at the time worked well at reducing recoil, but he was chasing his reticule. Werries believed he could come up with a design that would hold the reticule on target throughout recoil. After about a year of testing and refinement, Werries and Rat Worx joined together to put the Big Chubby on the market. Several Big Chubby brakes have been tested extensively at numerous sniper schools with awesome results. With proper body alignment, shooters have been able to hold their reticule on a 2" circle at 100 yards throughout recoil. The Big Chubby muzzle brake is designed for speed and accuracy.

I would be interested in trying this brake but I have an LMT 308. I have a 5/8-24 thread. I dont see a 5/8ths thread on your site. What happens if you run this brake the way it is (with correct threads) on an auto?

The baffle angles are tuned for a bolt gun. It will take some prototyping to get it right for the semi-autos. The ammo used is either Hornady 168 TAP or a duplicate load of a 168 A-MAX with 44.8 gr. of Varget. Both loads are running at 2725 fps in this rifle.

Do that with a semi auto so we know your not using low power loads. What grain ammo and what powder charge? A 90gr bullet with 50% powder could make a low recoil like that without any brake.
