The Hawke Sidewinder 30 FFP 4–16x50 (Model 17451) is a first focal plane riflescope engineered for precision shooting, hunting, and target sports. Built on a 30 mm mono-tube chassis, it features Hawke’s System H5 optics with 18-layer fully multi-coated crown glass and a 50 mm objective lens. The First Focal Plane (FFP) illuminated MOA reticle keeps subtensions true across the entire 4–16x magnification range, allowing for consistent holdovers and range estimation at any zoom setting. It utilizes push-pull locking exposed turrets with 1/4 MOA click values and an integrated revolution witness window to maintain zero reference.

Key Features

• System H5 Optical System: 18-layer fully multi-coated low-dispersion crown glass delivers a 24° ultra-wide field of view (31.8 to 8.1 ft @ 100 yds / 10.6 to 2.7 m @ 100 m) with 102 mm (4.0 inches) of eye relief.
• First Focal Plane (FFP) MOA Reticle: Glass-etched reticle with multi-intensity red illumination powered by a single CR2032 3V battery, keeping sub-tensions proportional at all magnification levels.
• Resettable Locking Turrets: Exposed push-pull turrets provide positive 1/4 MOA adjustments with an internal witness window indicating turret revolution position.
• Side Parallax Focus: Side focus adjustment operates smoothly from 9 metres (10 yards) to infinity and accepts the included 4-inch clamp-on side wheel.
• All-Calibre Rated Chassis: Nitrogen-purged, shockproof, and waterproof 30 mm mono-tube body designed to handle heavy magnum centerfire recoil as well as harsh spring-piston airgun cycles.
• Included Accessories: Ships with a removable 4-inch side wheel, 4-inch screw-in sunshade, removable zoom throw lever, bikini-style lens covers, and a lens cloth.

Who is the Hawke Sidewinder 30 FFP 4-16x50 for?

• Long-range varmint hunters — Requires precise shot placement at distance, provided by this first focal plane riflescope through its 4–16x magnification range and light-gathering 50 mm objective lens that keep MOA holdovers accurate at any zoom setting.
• Precision rimfire shooters (NRL22 / PRS Rimfire) — Benefits from the side parallax that focuses down to 9 metres (10 yards) alongside a 30 mm mono-tube chassis featuring exposed, locking 1/4 MOA turrets for rapid dialing between close and mid-range stages.
• Field target airgun competitors — Relies on the included 4-inch removable side wheel attaching to the 9-metre minimum side focus mechanism for fine range estimation across the variable 4–16x optical system.

Less suitable for: Lightweight stalking setups requiring a sub-500 g optic (where this 725 g scope adds excess carry weight), shooters requiring metric adjustments (who are better served by an MRAD-turret riflescope), or dedicated benchrest and extreme long-range target shooting requiring higher-magnification configurations such as a 6–24x56 or 8–32x56 optic.
