Holosun 507 Comp / 407 Comp Gen 2 SBGW Target Focus Trainer
Stonebridge Gunworks · Target Focus Trainer
Train target focus. Not dot chasing. The SBGW Target Focus Trainer partially occludes your Holosun 507 Comp or 407 Comp window, so you hold focus on the target while your brain overlays the dot — the same visual process you want in a match.

Comp models only. This does not fit the standard Holosun 507C or 407C. The Comp models have a larger optic body and use a different trainer.
What It Does
FocusTarget focus, not dot focus
Occlusion keeps your eyes on the target while your brain overlays the dot onto it.
PresentationStops dot chasing
No more hunting the window on the draw. The dot shows up where you are already looking.
Dry + LiveWorks for both
Use it in structured dry fire and on the range during live fire practice.
ConsistencyRepeatable visual process
Builds the same visual sequence every rep, so it holds up under match pressure.
GlareLow-angle sun help
Occlusion can cut visual distraction through the window when you are shooting into the sun.
Match readyTrain on your match optic
No swapping optics or guns. Train with the exact setup you compete with.
How Occlusion Training Works
Occlusion training works by partially blocking the optic window. You keep hard focus on the target and let your brain place the dot on it, instead of shifting focus back into the optic to find the dot. That reinforces the exact visual process used in practical shooting and competition, and it pays off in presentation, target transitions, and shot calling.
- Mount the trainer so it partially occludes the optic window.
- Keep both eyes open and hold hard focus on the target.
- Present the gun and let the dot arrive in your vision — do not go looking for it.
- Call the shot from the color you see on the target — target focused, not dot focused.
- Run it for part of each session, then pull it and shoot clean to compare.
Fits These Optics
Pick the optic you actually run. Every optic below uses the Comp body this trainer is cut for.
This does not fit the standard Holosun 507C or 407C.
The Comp models have a larger optic body and use a different trainer. Not sure which you have? Check the box or the optic — Comp models are noticeably wider. See all TFT trainers to find the one for your optic.
Recommended Setup
For best results, pair your Holosun 507 Comp or 407 Comp with a direct-milled slide and use the trainer as a standing part of your dry fire and live fire routine.

Frequently Asked Questions
Will this fit my 507C or 407C?
No. This trainer fits only the Holosun 507 Comp and 407 Comp. The standard 507C and 407C have a smaller optic body and this will not fit them. Not sure which you have? Comp models are noticeably wider — check the box or the optic.
Does one trainer cover both the 507 Comp and the 407 Comp?
Yes. The 507 Comp and 407 Comp share the same Comp optic body, so this single trainer fits either one.
Is this only for dry fire?
No. The Target Focus Trainer can be used for both dry fire and live fire training.
What is occlusion training?
Occlusion training partially blocks the optic window so you stay focused on the target while your brain overlays the dot, which reduces dot chasing and improves presentation.
Does it help with low-angle sun glare?
It can. Depending on lighting and range conditions, the occlusion effect reduces glare and visual distraction through the optic window.
