The Burris Fullfield 4-16x50mm Wind Reticle, Side Parallax Adjust (SPA), Knob Synergy - Exposed (KSH-Ex) Riflescope (Model 201552) is a high-performance second focal plane (SFP) optical instrument engineered for mid-to-long-range hunting and precision target shooting. Built with a 1-inch single-piece aluminum tube, this non-illuminated scope features fully multi-coated lenses and a 50 mm objective lens to maximize light transmission. It integrates advanced exposed turrets featuring the Burris Knob Synergy® System, allowing shooters to upgrade the elevation dial to custom ballistic laser-engraved knobs or zero-click stop setups. Backed by a double-spring tension turret system, it ensures reliable tracking and point-of-impact hold under heavy recoil. As a fully passive optical instrument, it requires no batteries or Australian SAA/RCM electrical safety certifications, making it ready for immediate field use.

Key Features

• Knob Synergy® System: Features advanced exposed turrets that allow users to easily swap or upgrade the elevation dial to custom ballistic elevation rings.
• Precise Windage & Elevation: Utilises 1/4 MOA per click adjustments with a double-spring tension system to maintain zero under heavy centrefire recoil.

Who is the Fullfield 4-16x50mm Wind Ret Spa Ksh-Ex for?

• Long-range varmint hunters — requires the variable 4-16x magnification and 50 mm objective lens of this Burris Fullfield 4-16x50mm riflescope to identify and ethically target small game from 25 yards out to approximately 400 yards.
• Open-country predator hunters — utilizes the non-illuminated Wind Reticle and 1/4 MOA click values of this Burris Fullfield 4-16x50mm scope to make fast holdover adjustments under variable wind conditions.
• Precision target shooters — leverages the side parallax adjustment from 25 yards to infinity and the Knob Synergy® exposed turrets on this Burris Fullfield 4-16x50mm optic to quickly dial exact elevations for varying target ranges.

Less suitable for: shots beyond 400 to 500 yards, where tactical dial-up platforms with larger 30mm or 34mm main tubes are preferred to provide the necessary elevation travel, or where higher magnification ranges are required.
