Founded in June 2021, JJ Armory has grown into one of Long Island’s premier firearm retailers and customization shops, proudly serving the local community from our home at:

38 W Main Street, Riverhead, NY — next to Diggers.

What began as a small-town shop rooted in respect for the Second Amendment and firearm safety has evolved into a full-service operation offering sales, gunsmithing, Cerakote, laser engraving, and optic cutting — all done entirely in house.

When we say “in-house,” we mean it — no outsourcing, no middlemen, and no shipping your firearms elsewhere. Every Cerakote job, engraving, and optic cut is completed right here by our own team using state-of-the-art laser and machining technology.

• Laser Engraving: From custom logos, serial markings, and stippling patterns to full receiver or slide engravings, we bring your vision to life with precision fiber-laser detail.
• Cerakoting: Our certified applicators offer everything from single-color coatings to complex custom blends, creating durable finishes that protect and personalize your firearm.
• Optic Cuts: We perform precision slide milling for red dot optics — ensuring perfect fit, function, and alignment.

Our mission is simple: to combine quality, safety, and service into every interaction. We’re here for enthusiasts, hunters, and first-time gun owners alike — offering not just sales, but education, guidance, and support.

At JJ Armory, we don’t just sell firearms.
We build relationships, craft precision, and earn trust — one customer at a time.
