There are three primary modifications required for proper Super Safety operation.
​
1. Trigger Modification
Begin by cutting the trigger as shown in the photo below.
-
The right-side cut should be approximately 45–60 degrees. This cut is mainly for clearance, so the exact angle is not critical.
-
On the side of the trigger that must be rounded, start with a small radius and increase it gradually.
Function test:
Reinstall the Super Safety cam and lever, along with the trigger, with the Super Safety set in the middle position. Hold the trigger to the rear as if firing, and manually rotate the lever. The trigger should move slightly forward and backward.
-
If there is no movement, continue rounding the corner until proper engagement is achieved.
​
2. Safety Detent Pin Modification
The safety detent pin simply needs to be rounded, as shown in the photo. This step is straightforward and ensures smooth lever movement.

3. Upper Receiver “Shelf” Modification (Recommended)
This modification is not always required depending on your upper receiver, but is strongly recommended to avoid jamming issues later. When the charging handle is pulled or the BCG is fully to the rear, the Super Safety lever can get wedged against this shelf.
​
Remove the BCG and grind back the section of the upper receiver shown in the photo.
In the example photo, the area has only been slightly relieved, but many users prefer to grind the shelf completely flush for maximum clearance.

AR-9
Setting up an AR-9 for a Super Safety requires additional work, and the exact steps will depend on the parts you’re using. I’ve provided a link to a very informative video that explains the full process.
