The story of NPO Top mount picatinny rail

In 2023, a deep collaboration with professional users in Eastern Europe taught us a pivotal lesson in practical design. They were using our first-generation FMR335 thermal imaging scope and came back with a specific, hardware-focused request: “We need a Picatinny rail on top.”

Initially, we wondered why. The answer revealed a critical need for tactical flexibility. In high-intensity use, constantly swapping between a daytime optic and a thermal scope is inefficient and can compromise zero. These users needed a permanent, unified weapon platform that could adapt in an instant.

Their logic was brilliant in its simplicity:

  • Mount a red dot sight on the newly added top Picatinny rail.
  • Leave the thermal scope on the main rail underneath.
  • Daylight/CQB: Use the always-ready, zero-power red dot for speed.
  • Darkness/Concealment: Flip on the thermal scope for imaging.

This configuration eliminates the “dead scope” dilemma. Imagine a coyote appears at 40 yards in broad daylight. Your rifle is equipped with this hybrid system. You raise it and the red dot is instantly live—no waiting for a thermal scope to boot. You take the shot. The top-mounted Picatinny rail just turned a specialized night-vision tool into a 24/7 ready rifle.

That user request directly shaped our product line. We now design key models with an integrated top Picatinny rail, recognizing it’s not just an accessory point but the cornerstone of a dual-purpose sighting system. It’s a testament to building what users truly need, not just what we think they want.
