Vortex Razor HD LHT 3-15x50 – G4i BDC (MRAD) (RZR-31503)
20.5 ounces of Razor-grade glass with an illuminated BDC reticle and a dial-capable locking elevation turret. The 3-15x50 is the LHT for hunters who want a lower bottom-end magnification for close timber work and enough top end to reach across a canyon — without the weight penalty of a dedicated long-range scope. Vortex SKU RZR-31503, UPC 843829108959.
3x at the Bottom Matters
A 3x low end gives you a genuinely usable field of view in close cover — 35.3 feet at 100 yards — where a 4.5x or 6x scope leaves you hunting for the animal in the glass. At the top, 15x is plenty for identifying and shooting at the distances most western hunting actually happens.
The G4i BDC Reticle
The G4i BDC is an illuminated reticle (that's what the "i" means) with reference marks to compensate for bullet drop and bullet drift. Vortex describes it as usable effectively with a variety of firearms — it's a hunting reticle designed to give you holds without the visual clutter of a full precision grid. Push-button illumination runs on a CR2032, included.
Second Focal Plane
This model is second focal plane, which means the reticle stays the same visual size through the zoom range. It's the traditional hunting configuration: the reticle never gets too fine to see at low power or too thick at high power, and the BDC marks are calibrated for a specific magnification — check the subtension chart for the correct setting.
RevStop and a Locking Turret
The patented RevStop Zero System gives an easy-to-set, reliable return to zero after dialing — the thing that matters when you've dialed for a shot, the animal moved, and you need to get back to your baseline without thinking about it. The locking elevation turret prevents accidental adjustment in the field. A RevStop Zero Ring is included.
Razor Optics
Class Leading HD Optical System, APO (Apochromatic) System, optically indexed lenses, XR Plus coatings, and ArmorTek exterior protection — in a 30mm tube machined from a single solid block of aircraft-grade aluminum, argon purged and O-ring sealed.

The 3-15x50 is the hunting-first choice — wider field of view, a simpler BDC reticle, nearly twice the windage travel, and an ounce lighter. The 4.5-22x50 is the precision-first choice with FFP and a full ranging reticle.
Frequently Asked Questions
Is the reticle illuminated?
Yes — the "i" in G4i means illuminated. Push-button, CR2032 included.
Is it first or second focal plane?
Second focal plane. The reticle stays one visual size through the zoom range, so the BDC marks are calibrated for one magnification — see the subtension chart.
How much elevation do I get?
23 MRAD total, 11 MRAD above zero with the RevStop ring installed.
