Romeo 5 Gen II version here
More killflashes can be found here
- v2 Update: I switched to PETG-CF for better heat resistance and doubled the hex depth to prevent glare from more angles.
- Precise Fit: Friction fit killflash ARD tightly fits on the end of the Romeo 5 optic. This does not fit the Gen II model. 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.

Perfect fit and well crafted. It looked even cleaner in person than in the photos. I'm usually skeptical about 3d printed parts due to the lack of quality control in the community. Must say you've earned my respect with this piece. I am a photographer as well; I attached a few higher quality photos to my review to help show how nice it really is. Here's hoping they won't be compressed by the website and because blurry.
Fits perfect no problems at all will be ordering more in the future for other scopes and red dots.
I purchased the option with the center hole cut out. Part fits snug, no jagged “burrs” on edges from the print , conceals the optic glass signature as intended. Doesn’t interfere with sight picture, and not even noticeable with a magnifier. Recommend!
Works exactly as stated . Very happy with how it came out and it fits perfectly, thank you!
I've purchased from 100 concepts and hammy. You will get a great product and way more value here at Hammy's shop. I have many of his products and they have all been great and very functional with very precise fit and finish.
Fit is excellent, came a bit shiny needed th sand of the shiny parts other than that it is worth the money,looks badass
