Styrka S7 2.5-15x50 SF Riflescope Illuminated Plex  Review

The Styrka S7 2.5-15x50 rifle scope is the flagship model of the Styrka S7 rifle scope family. A powerful 6x zoom ratio makes this scope well suited to nearly every type of hunting, from dense upland hunting to long range big game. Available with illuminated plex and illuminated mildot reticles, the Styrka S7 2.5-15x50 also features a large 50mm objective for maximum low-light performance at dawn and dusk.

First impression of this scope is that it's a hefty, solid scope. At 13.5" long, it tips our scale at 23.8 ounces. The 30mm tube is made from a single piece of 6061-T6 aircraft grade aluminum and is fully waterproof and fogproof, standard for any rifle scope worth its price. The turrets are very low profile, but the combination side focus/illumination knob on the left protrudes about an inch out from the body. One thing that we really like about this scope is the aesthetics. The curves of the body on this scope are more gradual and sweeping than most other scopes, which can seem blocky and angular in comparison. The photos will show you what we mean by this.

At the price point the S7 2.5-15x50 fits into, you expect solid build quality. This scope has it. Super tight tolerances abound, and nothing on this scope feels cheap, and no corners seem cut. The quick focus eyepiece is moderately tight, but operates smoothly with no grinding or tight spots. The focus ring is pretty quick considering the zoom ratio, and requires a half a turn to go from 2.5x to 15x. It's also quite tight, but that is alleviated due to the grip provided by the rubber ring and its raised ridges. It does seem to loosen up a bit with some repeated use.

The turrets are designed in the hunting style, with aluminum caps that hide the mechanisms. In keeping with the theme, these caps also have studded sections (raised ridges) around the edges to provide additional grip while on the range. The turrets themselves are adjusted in 1/4 MOA increments, and do provide light audible feedback.

The left side of the body features the combination side focus and illumiantion adjustment. The side focus is adjusted with the inner knob on the left side turret, and is adjustable to 10, 20, 30, 50, 100, 200, 500 yards, and infinity. It is surprising to see a rifle scope with this power and zoom ratio that can be set to 10 yards. The illumination, powered by a CR2032 battery inside the knob, has six different settings with an off position between each. This is advantageous because you can set your desired brightness, and always be a single click away from turning on the illumination. As far as brightness, the lowest setting fully illuminates the reticle, but very dimly - desirable for low light situations where your vision has adjusted to available light. Stepping up through illumination settings shows the reticle brightening at even intervals, up to the sixth and brightest setting, which can be seen against dark backgrounds on a very bright day. The reticle is evenly illuminated at all levels.

The most important thing to consider with any new rifle scope is how well the optics perform. The Styrka S7 2.5-15x50 provides some extremely clear and sharp views at any magnification, and that clarity and sharpness continues directly to the edge of the sight picture. Color bias is very neutral, and we were unable to pick out any difference in color between what we saw through the scope and what we saw without.

At 2.5x, the S7 2.5-15x50 does exhibit some field curvature, though this is minimized by maintaining correct eye position. This "pincushion" effect is rather common with scopes with a high magnification ratio, so it is to be expected. Also, at low magnification, chromatic aberration is all but nonexistent. At higher magnification, the field flattens out considerably, and chromatic aberration is only really noticeable when viewing high contrast objects, and during movement. Otherwise it seems pretty well controlled, in line with other scopes we've seen at this price point.

Overall, the Styrka S7 2.5-15x50 earns a passing grade from us. It's built well, looks good, functions well, and the warranty is unmatched. Styrka gets our stamp of approval, and we'll stand behind this scope 100%.

The 30mm tube is completely waterproof, fogproof, and nitrogen purged.

Care and Feeding of your Styrka Rifle Scope

Your Styrka rifle scope is designed to provide you with years of dependable service in the field if cared for and stored properly.

  • Protect the rifle scope from direct impact and do not force any of the moving parts beyond their limits.
  • Protect the optics of your rifle scope by putting on the neoprene scope cover when not in use.
  • Store your rifle scope in a cool, dry place whenever possible.
  • When storing for off-rifle for an extended period of time, place the rifle scope in a plastic bag or airtight container with a dessicant.
  • Do not leave the rifle scope in a car on a hot or sunny day, or near anything that generates heat as this may cause damage.
  • Clean any dust, dirt, or water that may get on the rifle scope or inside moving parts as soon as possible. This prevents unforseen damage to mechanical parts of the scope.

Proper cleaning of the lenses is essential to maintaining the optical integrity of your rifle scope. Dirty lenses diminish the amount of light transmitted through the rifle scope and your overall viewing experience.

  • Remove any dust on the lenses with a soft lens brush or can of pressurized air.
  • Using the included microfiber cleaning cloth, rmove any fingerprints, stains, or smudges from the lens surface by rubbing in a circular motion. Start in the middle of the lens and work your way to the edges. Breathe lightly on the lens to provide moisture, if needed.
  • For a more thorough cleaning, we recommend the use of a lens/optics cleaning kit. Follow directions included with your kit for best results.
