This is the newly designed slabbed 5 port "Muscle" brake. I reconfigured the ports along with adding an additional port over the famous 4 port. The result is the most effective brake out there today for its size. It has the same recoil reduction as the magnum 4 port but is in a much smaller package. This brake will fit muzzle diameters from .685" to 1". Recommended for magnum cartridges.
Requires gunsmith to time the brake, open the bore diameter, and blend the backend into the barrel.
5/8x24 and 3/4x24 threads available

Ordered this brake and it shipped next day and arrived 2 days after that, awesome customer service right there! Product is as described and cant wait to shoot with after my gunsmith installs it.

I had been struggling with a Remington 700P .338 LM for years; Three Shilen barrels, heavy recoil lug, 2 new Manors stocks, swapping scopes, new trigger, a different brand of muzzle brake, etc... The best I could do with my match reloads was 1.25 MOA... I read a blog suggesting this type of muzzle brake.. I just got back from the range shooting the Slabbed 5 Port. The first and only 5 shot group for the day was .5 MOA, and a pleasure to shoot. I didn't notice any concussion, and I estimate that the recoil was reduced 75%. That may be off, but that's what it felt like. On a 32x Nightforce, the sight picture stayed on target most of the time. I shot it prone on dirt, and I didn't notice any dirt kick up. Keep in mind a gunsmith has to properly bore and time it, but this is the ONLY muzzle brake I'll ever buy again.
