Holosun - Optic Cut

Please Note: This is a machining service only. You are sending us your slide and in some cases your optic as well — the optic and slide are not included with this service.

Our cuts are precision CNC machined to exact tolerances using our cradle cutting method, which keeps the footprint intentionally tight. This ensures your optic locks in solid with little to no movement once mounted.

When applicable, we also add precision-cut recoil bosses. These help direct the stress of recoil into the slide, not just the screws — giving you better long-term reliability under heavy use.

Whether your setup is for competition, duty, or everyday carry, our optic cuts are made to hold up to serious firing schedules without shifting or loosening.

⚠️ Important: After machining, the cut exposes raw metal. We strongly recommend selecting one of our coating options to prevent corrosion. If you choose “No Coating,” you're accepting the risk of rust or finish damage from moisture and exposure.

***For customers purchasing the C series optic cut in order to use the 509 adapter plate, the standard cut will not be the correct length. If you want to use the adapter plates, please specify this intent in your individual order notes. The cut will be cut slightly oversized for their plate (your C series optic cut will NOT have a tight fit).***

For Customers getting a 509T Milled, our cut has a relief on the right corner. This is by design. This is not a mistake, nor sloppy machining, its due to the nature of the mounting system. The picture below is a reference of what the cut will look like once complete.
