This Keck Precision 34, 5-30x56 FFP IR riflescope was sent to me by Sure Shot Airguns, and it clearly demonstrates a product that aims to deliver a wealth of magnification while maintaining an economical price point.

The Keck Optics Precision 34 5-30x56 FFP IR riflescope mounted on a rifle on a tripod.
The Keck features a 34mm main tube and a 56mm objective lens. It comes supplied with Picatinny-compatible extra-high scope rings, which streamline the mounting process and are especially useful for full-length Picatinny rails that are becoming increasingly common on modern air rifles, the primary intended market for this optic.

High Picatinny-compatible rings are supplied.
A 76mm sunshade is included, along with front and rear flip-up lens covers. The large 56mm objective is designed to maximise light entry and is well matched to the 5-30x magnification range, made possible by a 6x erector system.

Keck supplies flip-up lens caps and a throw lever.
Elevation and windage are adjusted via large, 38mm-diameter, heavily knurled external turrets. Click values are 0.1 MRAD (10mm at 100m), with 10 MRAD (100 clicks) per full rotation. The clicks are tactile and audible, with smooth movement and minimal overrun.

The 38mm turrets are easily gripped and offer consistent, tactile, audible clicks.
The elevation turret is non-locking but features a straightforward zero-stop setup for initial zeroing. Windage adjustment is controlled via a matching turret on the right side of the saddle, incorporating a “lift-to-unlock and turn” design. Graduations are clearly marked both left and right of centre.

The windage turret is marked left and right of centre.
Both turrets feature a coin-slot dial cap for floating the dial when zeroing. The elevation turret’s zero stop is set via a small Allen key and three grub screws that lock it in position.

The zero-stop set-up involves three grub screws.
Parallax adjustment is on the left side of the saddle, in the form of a similarly knurled collar, adjustable from 10 yards to infinity. This is where the scope stands out for airgun use, as its close-focus and parallax adjustment capabilities make it suitable for high magnification at extremely short distances. That’s not to say it cannot be used on rimfire or centrefire rifles, but over half of the parallax collar’s rotation is dedicated to 10 to 50 yards. By contrast, from 100 yards to infinity, parallax adjustment requires less than 1/8 of a turn. This design choice clearly prioritises precision focus at short distances, aligning with its airgun-centric intent.

The parallax goes from 10 yards to infinity, but the spacings are a little imprecise at greater distances.
Illumination control is located at the outer edge of the parallax collar and offers six levels of reticle brightness. Only the very centre of the reticle illuminates red, with intermediate settings acting as off positions. There is no auto shut-off, so be mindful not to leave it on. Power comes from a standard CR2032 battery housed under a capped dial, accessible with a coin or the plastic tool that comes with the scope.

A polymer tool is supplied, just in case you don’t have a penny.
Keck uses what they call the G2A reticle, positioned in the first focal plane (FFP). It’s a clean and practical design, featuring an open “Christmas tree” layout in the centre, with broader lateral holdover arms. Being FFP, the reticle size increases with magnification, so the MRAD hash marks always match the turret values, ensuring precise dialling or hold-offs for windage and elevation.

The FFP reticle offers a nice balance of precision aim-offs without being too cluttered. Only the centre cross illuminates.
The magnification is controlled by a rotating collar on the ocular housing, ranging from 5x to 30x. It features solid end stops and rotates smoothly throughout its range. No perceptible internal mechanical noise or movement was noted, indicating a good standard of build quality. A throw lever is supplied, although the collar’s generous knurling provides excellent grip with either bare or gloved hands.

The throw lever is removable.
Keck advertises an HD optical system using high-quality glass and fully multi-coated lenses. This translates to excellent image clarity, accurate colour rendition, and over 90% light transmission. As expected, the body is made from aircraft-grade aluminium and is waterproof, fog-proof, and shockproof. I didn’t experience any issues in this regard, although I tested it during dry summer conditions, where heat shimmer/mirage presented its own challenges. At close range, parallax could be precisely neutralised, and the focus worked perfectly in tandem. The rear of the ocular housing includes fast-focus dioptre adjustment, allowing the reticle to be crisply resolved. Under field conditions, I found the image quality surprisingly relaxing on the eyes, something not always guaranteed at this price point.
The eye relief is 95 to 96mm, which is refreshing. When manufacturers push eye relief past 100mm, you often get a very tight eye box and reduced forgiveness. Premium optics tend to hover around the 90mm mark for a reason. The Keck strikes a sensible middle ground here, offering a noticeably more forgiving shooting experience than “magnum-capable optics”, especially when shooting from less-than-ideal positions.
Total elevation travel is 26 MRAD, with 17.4 MRAD available for windage. The scope tracked reliably when dialled back and forth within a 15 MRAD window during a variety of target scenarios. The reticle is not overly busy, and aiming was precise. The illumination was sharp and free of light bleed. Overall, the scope met or exceeded all of its advertised claims.
The Keck Optics Precision 34, 5-30x56 FFP IR riflescope is a feature-rich optic that offers excellent performance for airgunners and rimfire enthusiasts alike. With thoughtful design choices such as close-range parallax precision, an FFP reticle, and tactile turrets, all wrapped in a rugged, clear optic, it offers strong value in a competitive market segment.
