The scope utilized for this review is the Spectra 6X, featuring a magnification range of 1.5 to 9 and a 32-millimeter objective lens. It is worth noting that these specifications are highly specific, rendering the scope ideal for activities such as stalking and mountain hunting. This is primarily due to its lightweight construction, which further enhances its suitability for these purposes in my opinion.
Due to its 1.5 times magnification, this scope can also be used for driven hunt. While not ideal for this purpose, it is still manageable, in my opinion.
This scope features a 30-millimeter main tube diameter. It is equipped with a fixed parallax set at 100 meters and capped turrets. The scope has an outer objective diameter of 39.3 millimeters, making it ideal for use with night vision or thermal clip-on devices.
When examining the built properties, we find that the scope boasts a European-style eyepiece. The adjustment mechanism offers a smooth yet firm feel, which, in my opinion, is perfect for ensuring that accidental movement is avoided during hunting expeditions. Additionally, the eyepiece stands out as the only part of the entire scope that is rubberized. The remaining parts of the scope are crafted entirely from metal.
The magnification ring boasts a pleasant texture, providing a firm and secure grip. Notably, it is equipped with a throw lever, enhancing both grip and the ease of magnification adjustment. This feature ensures swift and efficient changes to the magnification level whenever necessary.
Overall, the entirety of the scope is crafted from metal. As previously mentioned, the ocular has a rubberized section, but aside from that, there are no plastic components. Even the caps on the turrets are constructed from aluminum.
The scope is designed to withstand the recoil of popular hunting calibers, including Magnum calibers. It is nitrogen-filled to prevent internal fogging, even in extremely cold environments. The scope measures 340 millimeters in length with the ocular in the inside position, and 350 millimeters when unscrewed.
Its weight is 550 grams, slightly higher than the specified weight of under 500 grams stated by GPO on their website. Upon measurement, the weight was found to be almost exactly 550 grams, a minor discrepancy of 50 grams. While not significantly off, it is worth noting.
The reticle in the Spectra 6X 1.5-9x32 riflescope is located in the second focal plane, ensuring its consistency throughout the entire range of magnification. Currently, there is only one available reticle option, which is the G4i. It is widely used in Europe for hunting purposes.
In my opinion, the reticle boasts a great illumination system. Utilizing optical fiber technology, it provides exceptional brightness and allows for precise adjustment of intensity. This brightness makes it suitable for use even on the sunniest of days, ensuring clarity when viewing white targets.
The illumination feature automatically turns off after three hours to conserve battery life. When you make your final adjustments within that time frame, the scope shuts off the illumination.
GPO SPECTRA 6x 1.5-9x32 Reticle G4i
The left side turret controls the illumination. Overall, there are eight intensity settings, with no intermediate off positions. This step-less design allows for precise adjustment, with the illumination growing stronger as you move towards level eight. The adjustments, even when small, are easily noticeable but not overly drastic. In my opinion, the illumination is perfectly designed.
The illumination battery is situated beneath the cap on the left side turret. For operation, a single CR 2032 battery is required.
When we look at the turrets, we notice that they are adorned with aluminum caps, providing a premium tactile experience. The absence of plastic caps enhances the overall quality and feel of the scope. Beneath these caps are great turrets that enable precise reticle adjustment.
The turrets rotate in a clockwise direction, similar to most European scopes. The clicks are not only pleasant to the ear but also provide satisfying tactile feedback, allowing you to perceive each individual click. In my perspective, these clicks are perfectly suited for a hunting scope.
Both the elevation and windage turrets are of the multi-turn variety and do not include a zero-stop or turn indicator. However, for a hunting riflescope, this configuration is perfectly acceptable.
Both the elevation and windage turrets are calibrated in milliradians. Each click of the elevation turret corresponds to an exact one-centimeter adjustment at 100 meters, while one complete revolution covers a distance of 6 MIL or 60 centimeters at the same distance.
The scope's internal elevation is specified as 40 MIL, but upon testing the turrets, I discovered that the actual internal elevation exceeds 50 MIL. Such a significant amount of elevation is typically unnecessary, even when engaging targets at extremely long distances.
Resetting the Elevation Turret to Zero
Resetting the elevation turret to zero is a straightforward process that can be done on the shooting range without the need for any special tools. Simply hold the lower side of the turret, unscrew the upper part, adjust it to zero facing forward, and securely tighten it back on. It's a convenient way to make adjustments without the hassle of carrying extra equipment.
The windage turret
The windage turret offers six milliradians of adjustment in a single revolution, similar to the elevation turret. However, it distinguishes itself by having markings in both directions, enabling left or right corrections of up to three MILs in each direction.
Resetting the Windage Turret to Zero
Resetting the windage turret to zero is accomplished in the same manner as adjusting the elevation turret. Start by unscrewing the upper part of the turret, then rotate it until the zero is facing forward.
The magnification ranges from 1.5x to 9x, allowing for precise adjustments with a simple 180-degree turn. With a lens diameter of 32 millimeters, this scope is optimized for daytime use rather than low-light conditions. As a result, it is an excellent choice for stalking or mountain hunting.
The parallax is fixed at 100 meters. The tunneling effect is non-existent, and the scope boasts an impressive light transmission rate of 90%.
Field of View
The scope offers a six-times zoom factor. At 1.5 times magnification, it boasts a wide field of view, spanning 28 meters at a distance of 100 meters. Even at its maximum magnification of nine times, it still maintains a respectable 4.6 meters at 100 meters.
Eye Relief and Eye Box
The eye relief of this scope measures 97 millimeters, which is a substantial distance. This generous eye relief makes it highly suitable for use with strong recoiling rifles, ensuring your safety while aiming. It allows for flexibility in positioning, whether you move closer or farther away from the scope while maintaining a crystal-clear image.
Now, let's discuss the eye box and the extent to which you can move behind the scope while maintaining a clear picture. I must admit, at 1.5 times magnification, it's remarkably forgiving. You have quite a bit of flexibility in your movements. However, at nine times magnification, it's noticeably more restricted, yet still satisfactory in my opinion.
The image quality itself is commendable, especially considering its price of 749 euros. The central part of the image exhibits excellent clarity and resolution. However, there is a slight drop in sharpness towards the edges. While the edge quality is still decent, there is a noticeable difference. The blurriness is confined to the outer edges and does not extend far into the center of the image.
The scope has a 30-millimeter main tube, but unfortunately, the Spectra 6X 1.5-9x32 does not come with a mounting rail option. Therefore, to mount the scope onto the rifle, you will need 30-millimeter scope mount rings.
