Looking for advice on marketing a small firearm accessory

I’ve been working on a small rifle accessory that solved a problem for me and it’s gotten a lot of positive feedback from people who’ve tried it. The hard part is figuring out where I can actually promote it. Marketing in the gun world is tricky. Most mainstream platforms restrict anything firearm related, even if it’s just accessories.

For those of you who’ve launched a niche product in this space, where did you find success getting the word out? Are there communities, forums, or advertising channels that actually work for small builders?

Not trying to spam anyone. Just looking for guidance from people who’ve already navigated this.
