Featherweight. Rugged. Ready for Anything.

The Vector Optics Frenzy-S SCRD-43 is arguably one of the lightest full-metal red dot sights in the world — tipping the scales at just 18.4g (0.65oz) without the mount. But don’t let the low weight fool you: this compact reflex optic is built to take serious punishment, shrugging off recoil from everything up to .338 Lapua Magnum without flinching.

With a 3 MOA red dot, motion-activated illumination, night vision (NV) compatibility, and IPX6 waterproofing, the Frenzy-S is ideal for dynamic use — whether you're topping a compact PCP, mounting it on your shotgun for driven boar, or co-witnessing it on top of a Vector Optics Paragon 4x24 Prismatic Scope for a fast-acquisition setup. It uses the MAG footprint, fully Shield RMS compatible, making it extremely versatile for modern sporting builds.

The motion sensor auto-on/off helps preserve the impressive 50,000-hour battery life, and the 8 brightness levels plus 2 NV settings mean you can tailor visibility to any lighting environment — from midday sun to pitch-black night.

Why we like it:
It’s absurdly lightweight, tough as nails, and runs forever on a single coin cell. The MAG/RMS footprint makes it perfect for pairing with the Paragon 4x24 Prismatic Scope (SCPS-M04), but it also stands alone brilliantly on pistols, shotguns, and carbines. This is a great example of Vector Optics getting the balance just right.
