Athlon Midas TAC HD 6-24x50 Review

Last updated Researched from published specifications and owner reviews, not tested in person

Quick answer

The Athlon Optics Midas TAC HD 6-24x50 First Focal Plane Riflescope, APRS3 FFP MIL is a 6-24x50 first focal plane riflescope with a true zero stop, priced at $569.00. At its maximum 24x, the 50 mm objective gives a 2.08 mm exit pupil, and the step up from Athlon's cheaper Argos line is glass quality and turret feel rather than any new feature.

The Midas TAC HD and the cheaper Athlon Argos BTR share the same magnification range, the same objective size and a nearly identical feature list on paper: first focal plane, illuminated mil reticle, zero stop turret. What separates them is not on the spec sheet at all. It is glass quality and turret feel, and turret feel is the harder thing to sell in a bullet-point list and the easier thing to notice at the bench with cold hands and a stage clock running.

At $569.00 this scope is positioned as a competition and precision-shooting tool where turrets get dialled every string of fire, not a scope that gets set once at the range and left alone for the rest of the season.

This review is researched from Athlon published specifications and owner-review consensus, not from a hands-on shooting session, and it distinguishes the sourced optical arithmetic from Athlon's own marketing language throughout.

What does "the step up from Argos" actually mean?

Athlon sells both the Argos BTR and the Midas TAC HD in a 6-24x50 first focal plane configuration with an illuminated mil reticle and a zero stop, and on a printed spec sheet the two look nearly identical. The difference Athlon and owner-review consensus both point to is HD glass in the Midas line, which affects color fidelity and resolution rather than anything expressible as a single number, and a turret mechanism that is reported as feeling more precise and more consistent under repeated dialling.

That distinction is genuinely hard to shop for, because neither glass quality nor turret feel appears anywhere on a data sheet. It shows up in owner reports of tracking consistency after a season of use and in subjective descriptions of image clarity at the edges of the field of view, which is exactly the kind of claim this review states as owner-review consensus rather than as a verified test result.

What does the 50 mm objective give you across the zoom range?

Exit pupil, computed

exit pupil (mm) = objective diameter (mm) / magnification at 24x: 50 / 24 = 2.0833 mm, rounded to 2.08 mm at 6x: 50 / 6 = 8.33 mm

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.

Twenty four power on a 50 mm objective narrows the exit pupil considerably, and the table below shows exactly where the useful range ends.

The Midas TAC HD gives a 2.08 mm exit pupil at its maximum 24x, a bright-day figure, against 8.33 mm at its minimum 6x.

Sourced figure

Exit pupil of the Midas TAC HD 6-24x50 by magnification
MagnificationExit pupilWhat it means
6x8.33 mmLarger than any human pupil can open to; the low end trades field of view for magnification, not brightness
12x4.17 mmComfortable through dusk for most adult eyes
18x2.78 mmA daylight setting, thinning as cloud cover increases
24x2.08 mmThe narrowest setting on the scope; a bright-day figure only

A shooter dialling long distance shots on an overcast day will get a noticeably brighter sight picture backing off from 24x to 18x, with almost no loss of practical resolution at typical PRS-style distances.

What does the Midas TAC HD zero stop actually do?

Athlon describes the turret as a "true precision Zero Stop," and the practical function is the same as every zero stop worth having: a mechanical limit at your established zero, so you can dial elevation up for distance and spin the turret back down until it stops without reading the numbers printed on the dial. This matters most under time pressure, which is exactly the condition a competition rifle sees on a stage clock.

The capped windage turret alongside an exposed elevation turret is a deliberate choice rather than an oversight: most stages and most hunting shots at distance require an elevation correction and a wind hold read off the reticle rather than a dialled windage correction, so protecting the windage turret from being bumped is more useful than exposing it.

What ring height and mount does this scope need?

Athlon's own published listing describes a 30 mm tube on this scope, so ring selection follows the same rules as any 50 mm objective on a common tube size. Check what ring height a 50 mm objective needs on a 30 mm tube before buying rings, since the objective bell rather than the tube diameter decides the height floor.

At 3.7 inches of published eye relief, mounting position matters more than on a longer-eye-relief hunting scope. Set the scope as far forward as your arm length and stock length comfortably allow, and confirm the full eye box is usable in your actual shooting position before torquing the rings down.

Where the Midas TAC costs you: paying for glass you cannot verify on a spec sheet

The honest limitation of this scope is that its entire value proposition over the cheaper Argos line is unverifiable from the spec sheet. You are paying roughly fifty percent more for glass quality and turret feel that Athlon describes in marketing language and owner-review consensus describes anecdotally, with no independent optical bench test published by either party that this review can point to. If Athlon's glass improvement matters less to your particular use case than it does to a competition shooter dialling every string, the extra cost buys less than it promises.

This is a real drawback and not a small one: on a spec sheet, the Argos and the Midas TAC are close to identical, and the case for the Midas rests entirely on a subjective claim this review cannot verify independently.

Budget alternatives and a genuine step up

Two directions, one cheaper and nearly spec-identical, one further up the price ladder with a verifiable difference on paper.

A dash means the manufacturer does not publish that figure. We leave it blank rather than estimating it.

The budget pick and the step up worth considering

The Athlon Argos BTR GEN3 6-24x50 Riflescope, APRS11 FFP IR MIL Reticle is Athlon's own budget alternative in the identical 6-24x50 first focal plane configuration with a zero stop, at a genuinely lower price if the glass and turret feel difference does not matter to your use. The Riton Optics 3 Conquer 6-24x50 MRAD FFP Precision Riflescope is a similar-price competitor from a veteran-owned company with an unlimited warranty, worth considering specifically for the warranty terms rather than any optical advantage. For a verifiable step up in tube size and travel, the Vortex Viper PST Gen II 5-25x50 First Focal Plane Riflescope, EBR-7C MOA moves to a scope with a documented reputation for turret repeatability rather than a described one.

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

Is the Athlon Midas TAC HD worth it over the Argos?

Only if glass quality and turret feel matter more to you than the roughly fifty percent price difference, since the two share nearly the same spec sheet. Owner-review consensus favors the Midas on both counts, but neither this review nor Athlon publishes an independent optical bench test to verify the claim.

What exit pupil does the Midas TAC HD give at 24x?

2.08 mm, computed exactly as the 50 mm objective divided by 24x magnification. That is a bright-day figure. Backing off to 18x opens the exit pupil to 2.78 mm with little practical loss of resolution at typical shooting distances, which is worth doing on an overcast day.

Does the Midas TAC HD have a real zero stop?

Athlon describes it as a true precision zero stop, meaning a mechanical limit at your established zero rather than a marked reference point on the dial. It lets you dial elevation up for a shot and return to zero by feel, which is the specific feature a competition rifle needs on a stage clock.

What tube size does the Midas TAC HD use?

Athlon's published listing describes a 30 mm main tube, the same size used across most of its precision line. The tube size affects available internal elevation travel rather than image brightness, and 30 mm covers the needs of most PRS-style and hunting-distance dialling.

Is capped or exposed better for the windage turret?

It depends on how you correct for wind. The Midas TAC HD caps its windage turret and exposes elevation, on the logic that wind is more often held off the reticle than dialled, so protecting the windage turret from an accidental bump matters more than leaving it exposed for quick access.

What ring height does a 50 mm objective need on a 30 mm tube?

Roughly the same range as any 50 mm objective on a common tube, since the objective bell rather than the tube diameter sets the height floor. Check the specific stocked heights that clear this objective before ordering rather than trusting a ring height name alone.

Researched, not professional advice. This page is compiled from published manufacturer specifications, published optical and ballistic formulas, and owner-review consensus, not hands-on testing. Figures described as a rule of thumb are shooter convention rather than sourced numbers, and they are labelled that way wherever they appear. Ballistic figures come from a point mass model using the ballistic coefficient the maker publishes, so treat them as a starting point and confirm them on paper at a measured distance. Confirm your firearm is unloaded with the action open before you mount, level, torque or bore sight anything. Verify a zero only on a supervised range or a safe, legal backstop, know what lies beyond your target, and follow the law where you hunt and shoot, including rules on land access and permitted cartridges.
