Bergara Rifles BA0007 ST-1 Self Timing Muzzle Brake, 5/8"-24 TPI, 6.5 Caliber

The Bergara BA0007 ST-1 self-timing muzzle brake is engineered to control recoil and muzzle rise on 6.5 caliber rifles, making it a practical choice for hunters and precision shooters who want to stay on target between shots. Built from 17-4 grade stainless steel with a nitride finish, this brake uses an angled baffle design that directs gas downward rather than venting it into your sight picture or kicking up dust on the ground—a real advantage when you're glassing for your next shot or spotting impacts at distance.

Threading at 5/8"-24 TPI, the ST-1 installs on rifles already chambered for that thread pitch. The self-timing feature takes the guesswork out of alignment; you thread it on and it indexes correctly without fussing with shims or wrenches to get the top port pointing straight up. That simplicity means less time on the workbench and more time in the field or at the range.

The brake arrives with a wrench and bubble level for installation, and its 2.5-inch length is long enough to be effective without adding excessive weight or dramatically extending your muzzle. If you're building a 6.5 Creedmoor or other 6.5 caliber precision rifle and want meaningful recoil reduction without the typical side-venting downsides, this is worth a serious look.

Frequently Asked Questions

Will this muzzle brake fit my 6.5 Creedmoor rifle?

The ST-1 is designed for 6.5 caliber rifles threaded at 5/8"-24 TPI. If your rifle's barrel is already tapped or has a muzzle that accepts 5/8"-24 threading, this brake will fit. If you're unsure of your barrel's threading, check with your rifle's documentation or a gunsmith.

Does the ST-1 require any special installation or alignment tools?

The self-timing feature means it indexes correctly without shims. The brake comes with a wrench for installation and a bubble level to ensure it's mounted straight, so most shooters can install it themselves with basic tools.

What's included with the brake?

The Bergara ST-1 comes with an installation wrench and bubble level to make setup straightforward.

How does the downward-venting design help when shooting?

By directing recoil gases downward rather than to the sides, the brake keeps your sight picture clear and avoids stirring up dirt or dust directly in front of your barrel—useful at the range or in the field when you need to see where your shots are going.
