Description
True 30mm aircraft aluminum geometry anchors the Hawke Sport Optics Sidewinder Riflescope 2020 edition, featuring an illuminated SR Pro II reticle, push-pull locking turrets, and witness window indicator. Built for precision centerfire bolt rifles and varmint guns, it provides 86 MOA elevation travel with 1/10 MRAD clicks, delivering precise dialing confirmation while maintaining robust turret mechanics.
Machined from high-tensile 6061-T6 aluminum, the thick-walled 30mm chassis isolates internal erector gears from receiver strain. Premium 18-layer multi-coated lenses deliver maximum light transmission, separating camouflaged targets from dense woodline shadows. Nitrogen gas purging prevents interior lens condensation during heavy downpours, meeting IPX7 waterproof standards. Weighing 25.6 ounces with a 13.3-inch length, this optic anchors tactical platforms, defining modern Hawke Sport Optics long-range riflescope capability.
Key Features of Hawke Sidewinder 2020
Precision shooters buy Hawke Sport Optics 4-16×50 Sidewinder 2020 scopes to exploit the patented witness window that tracks turret revolutions under match pressure. The push-pull locking mechanism prevents accidental elevation adjustments during field carry.
- 50mm multi-coated objective delivers sharp resolution across mid and long-range shooting distances
- 4-16x zoom range bridges tactical observation and extended 800-yard target engagements
- 1/10 MRAD exposed locking turrets yield distinct audible clicks that prevent over-dialing
- 86 MOA total elevation stroke accommodates steep long-range ballistic flight paths
- Second focal plane illuminated SR Pro II reticle provides precise marks and holdover brackets
- Witness window elevation turret displays internal scale revolutions to avoid lost zero position
- Sidewinder tactical riflescope erector components absorb heavy recoil impulses from .300 Win Mag rifles
- Side focus parallax dial eliminates focal error from 10 yards out to infinity
Sidewinder Turret Mechanical Travel Bounds
Dual erector tension springs keep the internal lens group centered, ensuring tracking accuracy within 1 percent across the 86 MOA elevation range. Tactical 1/10 MRAD turrets provide exact physical displacement per click without mechanical backlash. Rated for 1000G recoil forces, the internal glass reticle endures continuous fire from heavy match rifles. Operational temperatures span -20°F to 140°F, preserving nitrogen seals and smooth power adjustments.
Medium Receiver Scope Ring Alignment
The robust 30mm tube demands dedicated scope rings, providing 5.6 inches of mounting tube length. Medium-height rings keep the 50mm objective clear of heavy match barrels on continuous receiver rails. Torque ring cap screws to 15 to 18 in-lbs and mount base nuts to 40 to 45 in-lbs. Eye relief measures 4.0 inches, giving safe spacing behind heavy bolt guns.
Tactical Turret Handling Maintenance Steps
The side parallax knob turns with positive mechanical resistance, allowing deliberate focal correction without accidental movement. This tactical optic is not engineered for ultralight mountain rifles where light weight is paramount, nor for non-magnified close-quarter combat. Practice systematic maintenance to ensure lifelong field reliability.
- Clear dirt from objective surfaces using a lens brush every 250 rounds
- Check ring screws and rail mount hardware with a torque wrench every 500 rounds
- Clean external battery contacts and inspect turret O-rings every 12 months
