Indexing a muzzle brake is important to ensure that the recoil and noise reduction benefits of the brake are optimized. There are several ways to index a muzzle brake, but the most common methods are:
- Adjusting it with shims
- Using crush washer
- Using locknut
You must first understand and then fix the posture of the muzzle brake. The model you have dictates the position of the muzzle, which can have up-down or side-side holes. Some muzzle brakes have both side-holes and up-holes.
Radial brakes don’t need to be timed.
To do it with shims follow these steps:
- Rotate the muzzle brake to 12 o’clock, where the holes are perfectly aligned to where they’re supposed to. This will be the position we are looking for.
- Screw in the muzzle brake by hand and use a torque wrench to apply the force recommended by the manufacturer.
- Find out how much the brake rotates when you tighten it with the wrench. Subtract this distance from the ideal position and estimate the number and thickness of shims that will be needed to bring the brake into this position when screwing it in by hand.
- Add shims and retighten the muzzle brake. You can add them one by one until reaching the desired position.
- Finish indexing your muzzle brake using a torque wrench.
If your rifle is not properly aligned, it might result in damage to the muzzle over time. Additionally, if your rifle is not properly indexed, the muzzle may gradually shift as you use it – something we clearly want to avoid.

Indexing a muzzle brake is relatively straightforward. You can use a crush washer or jam nut for this purpose. The goal is to set the muzzle brake at 12 o’clock so that the side holes are horizontal.
Some advice on adjustment with crush washer:
- Always use a new crush washer.
- Use plenty of lube; anti-seize is a plus.
- Install the crush washer so that the flared side is facing the muzzle device and the narrow end is up against the barrel shoulder.
- Using a minimum of 20 and a maximum of 45 lbs. of torque, “crush” the washer.
- If you have a long way to go, only do quarter turns and then back it off. It will be crushed gradually in 1/8th of a turn increments. Because once it’s correctly oriented, you don’t want to back it off.

Indexing a muzzle brake is a process of measuring the angle and positioning of the brake on the barrel so that it optimizes its performance. There are many factors to take into account when indexing a muzzle brake, including caliber, barrel length, and weight.
The first step is to measure the diameter of the barrel at the point where the muzzle brake will be attached. Then you’ll need to measure the distance from this point to the center of gravity of the firearm. This can be done using a pendulum or lever arm balance. Once you have these measurements, you can use a calculation tool or chart to determine the optimal angle for your muzzle brake.
Indexing a muzzle brake is a process by which you determine the correct position of the muzzle brake on the barrel of your weapon. There are several ways to do this, but one of the most common methods is to use a dummy round and adjust the brake until it is centered on the bullet.
Once it is correctly indexed, you should mark the position of the brake on the barrel with a permanent marker or some other type of indicator. This will ensure that your muzzle brake remains in alignment even after rounds are fired.
A muzzle brake can be indexed by turning it in a clockwise or counter-clockwise direction. In most cases, it is best to start with the brake in the 12 o’clock position and make small adjustments until you have achieved the desired effect. It’s usually done by using shims, a locknut, or a crush washer. Be sure to use a marker to indicate the original position of the brake before making any adjustments.
Indexing a muzzle brake refers to the alignment of the brake with respect to the barrel of the gun. The goal is to have the brake centered on the barrel so that it can do its job properly and minimize recoil. There are a few ways to achieve this, but one of the most common is to use a set of shims to adjust the position of the brake on the barrel.
