- Dot Compatibility: Please ensure you choose the option to exactly match your red dot, as the sizes are different. If your model isn't listed, please contact me and we can work on getting a new version added.
- Precise Fit: Friction fit killflash ARD tightly fits on the end of a Holosun optic. This will require some force to install.
- Reduces Glare: The killflash reduces glare / reflections from the glass on the objective end of scopes. Due to needing to print with the front of the killflash on the print bed, there may be some shine to it which can be minimized by sanding or spray painting it.

The kill flash for my Holosun 503G red dot works great. We did some basic testing, where I had a buddy take a pair of binoculars to an opposite hill to look for the flash of my red dot with and without the kill flash and I will say it definitely makes a difference. My order was filled quickly and shipping was also really fast. So I have nothing but good things to say about this vendor. I'm actually going to buy a kill flash for my flashlight next.
Thank you Hammy3dprints!
Ordered this product as it’s impossible to find Holosun kill flashes and I’m thoroughly pleased. Not only did it arrive fast but it made the reticle of my Holosun 503G ACSS more crisp to my eye. It’s a pain to get on even using a mallet so I recommend taking a bit of heat to soften it up and then cooling once in place. Also don’t worry you don’t see the hexes when looking through your optic
This is the swankiest killflash. 10/10 vibe. This ain’t your grandmas whammy bar, this was built with intent by a man with an idea, and I think that’s pretty cash money. Love it babe.
Hammy was very responsive and helped me through the ordering process. The customer service was phenomenal as well as the products delivered. The fit was nice and snug with no failures after a couple hundred rounds. I highly recommend a kill flash for your red dot!
The kill flash came expediently and fit my Holosun 403R with impressive tolerance… as a matter of fact I couldn’t get it off of the sight with my bare hands (which I appreciate, because it’ll see some abuse). The polymer filament used feels sturdy and took to paint very well. I do wish the hexagonal baffles were a little smaller, or edited in some way that reduced lens reflection a little better but overall, I am pleased with the reflection elimination that the kill flash does provide! 10/10, would recommend.
This thing is awesome!!! It is very tight and will not come off!! There’s an upward indicating slot built into the cap to ensure the interior honeycomb is aligned perfectly. Take your time putting it on. I am completely satisfied with this purchase and you will be too! Thank you sir for a fine product.
Excellent killflash, looks and functions and fits as intended. I get all of my killflashes from Hammy. Please do one for a Holosun 512C so I don’t have to use another company!!!
