Why Choose a Direct-Milled Glock Optic Cut?
A direct-milled optic cut places the optic lower on the slide and creates a stronger mounting interface than most plate systems. This helps improve optic retention, reduces unnecessary stack height, and supports long-term reliability under recoil.
- Lower optic height compared to plate systems
- Improved mechanical fit and optic retention
- Full recoil lug support on compatible footprints
- Designed for high round count practical shooting use
- Ideal for USPSA Carry Optics, range training, carry guns, and performance Glock builds
Supported Optic Footprints
Available optic cut options include common competition and carry footprints such as:
- RMR / SRO / Holosun C-Series / Holosun Comp
- Holosun K / EPS Full / EPS Carry
- Vortex Defender ST / XL / DeltaPoint Pro
- Aimpoint ACRO
- Holosun 509T
Some footprints require deleting or relocating the rear sight dovetail due to optic length and slide geometry. Select the appropriate rear sight dovetail option before checkout.
Recommended Optics for Glock Direct Milling
For competition and practical shooting, we commonly recommend optics such as:
- Holosun 507 Comp
- Holosun 407 Comp
- Holosun EPS Full Size
- Holosun EPS Carry
- Trijicon SRO
- Vortex Defender XL
- oSight XR

Complete Your Glock Red Dot Setup
A direct optic cut is the foundation of a reliable Glock red dot build. For shooters building around USPSA Carry Optics, practical shooting, or high-round-count range use, the right supporting parts can make the setup easier to shoot, reload, and maintain.
Henning Glock 17/34/19X/45 Magazine Extension
A strong upgrade for Glock 17, 34, 19X, and 45 magazines. This is a popular option for USPSA Carry Optics and practical shooting setups where reliable magazine capacity and reload consistency matter.
The Henning extension is especially relevant for Glock 17 and Glock 34 competition builds paired with a direct-milled large-window optic.

GLOCK Performance Trigger
The GLOCK Performance Trigger is a clean supporting upgrade for shooters who want an enhanced trigger feel while staying with a Glock factory accessory.
For a practical Glock red dot build, we recommend choosing the optic and cut first, then selecting the trigger setup around your use case.

GLOCK Reversible Extended Magazine Catch
The extended magazine catch is a simple factory Glock upgrade that can help with reload access on Gen4, Gen5, and G19X-style setups.
This pairs well with a competition-focused Glock build using extended magazines, red dot optics, and high-repetition reload practice.

What Is Included
- Precision optic cut for your Glock slide
- Black oxide tool finish on the machined area
- Optic footprint fitment based on selected option
- Mounting screws for supported footprints when applicable
- Optional backup iron sight upgrades
- Optional red dot purchase and installation
This service includes the optic cut only. The slide and optic are not included unless specifically added through the product options.
Full Recoil Lug Design
We cut full recoil lugs on our Glock optic cuts where applicable. This provides a strong mounting solution for the RMR, SRO, Holosun C-Series, and Holosun Comp footprints by giving the optic a secure mechanical interface instead of relying only on screws.
For the RMR, SRO, Holosun C-Series, and Holosun Comp footprint, we provide McMaster-Carr 6-32 7/16 long screws for Trijicon optics and Holosun XControls metric taper 6-32 .320 screws for Glock direct cuts when applicable.
Backup Iron Sight Options
Backup iron sights can be added with your optic cut. Options include plain black serrated sights, tritium front sights, and tritium front/rear options depending on the optic footprint and setup selected.
If you are unsure which sight height or dovetail option to select, choose the optic footprint first and contact us before placing the order.
Train Your Glock Red Dot Setup
After the optic cut is completed, dry fire and presentation work become a major part of getting value from the red dot. Our SBGW Target Focus Trainers are designed to help shooters reinforce target focus instead of chasing the dot during presentation and transitions.
If you are building a Glock for Carry Optics, local matches, or regular dry fire practice, consider pairing your optic setup with a matching trainer.

Should I order the optic cut before choosing the red dot?
Choose the red dot or optic footprint first. The optic footprint determines the correct cut, screw setup, sight options, and whether the rear sight dovetail needs to stay, move, or be deleted.
