Vortex Strike Eagle 1-8x24 Review
Quick answer
The Vortex Strike Eagle 1-8x24 Second Focal Plane Riflescope, BDC3 MOA is a 1-8x second focal plane LPVO on the same 24 mm objective as Vortex's 1-6x24, priced at $307.99. Pushing the same glass to 8x drops the exit pupil to 3 mm, a real cost in eye box and low light performance for two extra powers of magnification.
The Strike Eagle 1-8x24 is not a different scope from the 1-6x24 reviewed separately on this site so much as the same platform with the erector pushed further. Same 24 mm objective, same illuminated BDC3 reticle family, same updated magnification ring with a thread-in throw lever. The entire difference between the two scopes is what happens when you ask the identical objective to support 8x instead of 6x, and that difference is worth stating in exact numbers rather than in adjectives.
At $307.99 the premium over the 1-6x24 buys genuine additional reach for target identification, and the honest question this review answers is whether that reach is worth what it costs at the top of the zoom range.
This review is researched from Vortex published specifications and owner-review consensus, not from a hands-on shooting session, and the exit pupil comparison against the 1-6x24 is exact arithmetic rather than an estimate.

What does 8x actually add over the 1-6x24 on the same objective?
Vortex describes the 1-8x24 as defined by speed and versatility, with a true 1x at the bottom adapting to close engagement exactly like the 1-6x24, and the updated illuminated BDC3 reticle offering holdovers Vortex publishes as usable out to 650 yards for a target of known distance. The true 1x setting is identical in character to the 1-6x24, both eyes open with no image shift, because neither scope changes how the objective or the erector behaves at minimum power.
The difference is entirely at the top. Two extra powers of magnification on an unchanged 24 mm objective is not a free upgrade, and the arithmetic below states exactly what it costs.
What does the 24 mm objective give you across the zoom range, and what does the extra 2x cost?
Exit pupil, computed
exit pupil (mm) = objective diameter (mm) / magnification at 8x: 24 / 8 = 3.0 mm at 1x: 24 / 1 = 24 mm for comparison, the 1-6x24 gives 24 / 6 = 4.0 mm at its own maximum
Exact arithmetic. A dark-adapted human pupil rarely exceeds 5 to 7 mm depending on age, which is a population convention rather than a published spec.
This is the single most important comparison in this review: the same objective, two different top-end powers, and a direct measurable cost.
Pushing the identical 24 mm objective from 6x to 8x drops the exit pupil from 4.0 mm to 3.0 mm, a 25 percent reduction for two extra powers of magnification.
Sourced figure
| Magnification | Exit pupil, 1-8x24 | Exit pupil, 1-6x24 for comparison |
|---|---|---|
| 1x | 24.0 mm | 24.0 mm |
| 2x | 12.0 mm | 12.0 mm |
| 4x | 6.0 mm | 6.0 mm |
| 6x | 4.0 mm | 4.0 mm (this scope’s maximum) |
| 8x | 3.0 mm | not available on the 1-6x24 |
Below 6x the two scopes are optically identical, since neither the objective nor the low end of the erector differs. The entire practical difference between them lives in the top two powers.
Does the eye box also get tighter at 8x?
Eye box, the range of head position that still gives a full, unvignetted sight picture, generally tightens as magnification increases on any variable scope, and a smaller exit pupil is part of the reason why: less light is exiting the ocular lens, so a given amount of head misalignment loses proportionally more of the image at 8x than at 6x on the same scope family. Owner-review consensus on this scope reports a noticeably less forgiving head position at maximum power compared with the 1-6x24 at its own maximum, which is consistent with the exit pupil arithmetic above rather than a separate manufacturing difference.
This matters most at speed. A shooter transitioning quickly between targets at 8x needs a more consistent cheek weld than the same transition at 6x, which is the practical cost of the extra magnification beyond the raw brightness numbers.
What ring height and mount does this scope need?
The mounting requirements are identical to the 1-6x24, since both use the same 24 mm objective and the same 30 mm tube. Check what ring height a 24 mm objective needs on a 30 mm tube before ordering, and use the included throw lever, which matters more on this scope than on a hunting optic because the magnification range you are actually using spans a full eight-to-one ratio.
Where the 1-8x24 costs you: a noticeably tighter package at the top of the range
The honest weakness of this scope is precisely the extra two power its name promises. At 8x, the 3.0 mm exit pupil and the tighter eye box that comes with it make this a meaningfully less forgiving optic at maximum magnification than the 1-6x24, and a shooter who bought the 1-8x24 expecting no compromise over the 1-6x24 except more reach will notice the difference specifically in dim light and at speed.
The published 650 yard holdover claim on the BDC3 reticle also deserves the same caveat given to any second focal plane BDC: those marks are calibrated for one specific magnification, and reading them at any other power gives an incorrect holdover distance, a limitation shared with the 1-6x24 and with every second focal plane reticle in this catalog.
Instead of 8x, or a step up for a wider eye box
The most direct comparison is the 1-6x24 built on the same platform, plus two alternatives that reach further without the same top-end trade.
| Model | Price | Magnification | Objective lens | Tube diameter | Focal plane | Illuminated reticle | Reticle |
|---|---|---|---|---|---|---|---|
| | $307.99 | 1-8x | 24 mm | 30 mm | Second | Yes | BDC3 MOA |
| | $225.75 | 1-6x | 24 mm | 30 mm | Second | Yes | BDC3 MOA |
| | $399.00 | 1-10x | 24 mm | 30 mm | Second | Yes | - |
A dash means the manufacturer does not publish that figure. We leave it blank rather than estimating it.
The 1-6x24 alternative and a longer-range competitor
If the tighter eye box and narrower exit pupil at 8x are not worth the extra reach for your carbine, the Vortex Strike Eagle 1-6x24 Second Focal Plane Riflescope, BDC3 MOA on the identical objective gives up two powers of magnification for a genuinely brighter, more forgiving top end, reviewed separately on this site. For a shooter who wants to go further than 8x rather than stop short of it, the Swampfox Arrowhead 1-10x24 SFP LPVO, Green BDC, 30mm pushes a 10x erector ratio on a 30 mm tube, at the cost of an even tighter eye box at its own maximum than either Strike Eagle offers.
How we chose
We did not test these optics in person and we never claim to. Picks are researched from manufacturer specification sheets, published optical and ballistic formulas, and the recurring themes in verified owner reviews. Every pick is matched to a real objective diameter, a real tube size, a real ring height or a real exit pupil rather than to a price bracket, and it is placed in the tier where its capability actually belongs. Where a figure is shooter convention rather than a sourced number we label it, and where a manufacturer does not publish a figure we leave it out instead of estimating it.

Frequently asked questions
What is the difference between the Strike Eagle 1-6x24 and the 1-8x24?
Both share the identical 24 mm objective, so below 6x they are optically the same scope. Above that, the 1-8x24 pushes two extra powers of magnification from the same objective, which drops the exit pupil at maximum power from 4.0 mm on the 1-6x24 to 3.0 mm here, a real cost in brightness and eye box.
What exit pupil does the Strike Eagle 1-8x24 give at full magnification?
3.0 mm at 8x, computed exactly as the 24 mm objective divided by 8x magnification. That is noticeably narrower than the 4.0 mm the 1-6x24 gives at its own maximum on the same objective, and it is the direct arithmetic cost of the extra reach this scope offers.
Is the eye box tighter on the 1-8x24 than the 1-6x24?
Yes, based on owner-review consensus and consistent with the exit pupil arithmetic: a smaller exit pupil generally means less tolerance for head position error at maximum power. The two scopes behave identically below 6x, since neither the objective nor the low end of the zoom range differs between them.
Is the Strike Eagle 1-8x24 good for a general purpose carbine?
Yes, if the rifle needs to both engage close and identify or shoot at extended distance, since 8x offers real reach the 1-6x24 does not. If the rifle is shot fast and close almost exclusively, the 1-6x24 on the identical objective gives a brighter, more forgiving top end for less money.
Do the BDC3 holdover marks work at 650 yards on the 1-8x24?
Vortex publishes the BDC3 reticle as usable to 650 yards for a target of known distance, but only at the magnification the marks are calibrated for, typically maximum power, since this is a second focal plane reticle. Using the marks at a lower magnification gives an incorrect holdover distance.
What ring height does a 24 mm objective need on a 30 mm tube?
The same modest height as the 1-6x24, since both scopes share the identical 24 mm objective and 30 mm tube. Most standard ring heights clear a 24 mm objective without difficulty, so ring choice on this scope is rarely the limiting factor in a build.
