Side-by-side specifications

First, which Strike Eagle and which Tango MSR?

Both names are families, not products, and that is the reason this comparison is usually answered badly. Ask a search engine to settle "Strike Eagle vs Tango MSR" and it will fairly ask you back which magnification you mean. Here is the map, read from both makers and the retailer, so you can skip that round trip.

Strike Eagle. Vortex currently builds it in 1-8x, 1-10x, 3-18x and 5-25x. There is no 1-6x24 in the line any more, which matters because that is still the model many people type: the 1-8x24 is what replaced it, and our retailer does not stock a 1-6x24 Strike Eagle at all. There are two different 1-8x24s. The one compared here is the first-focal-plane version, sold at around $500 and listed by Vortex for a good deal more. Its sibling, the AR-BDC3, is second focal plane, lists for less than the FFP and weighs 17.4 oz rather than 23.9 oz, so if you have read that the Strike Eagle 1-8x is heavy, that is true of this one and not of that one. Our retailer does not carry the AR-BDC3, so it is context rather than an option here.

Tango MSR. The 1-6x24 reaches our retailer as five separate models, and the price spread between them is larger than most people expect. The one we card is the black SOT61000, BDC6 reticle, accessories listed as standard, at around $260 . Beside it sit a gray OPMOD exclusive to that retailer sold with a 1.535 in mount, a Coyote Brown version, a black one carrying Sig's FL-6 Hellfire reticle instead of the BDC6, and a bundle with a TRYBE magnifier that costs far more than any of the bare scopes. Sig's own list price for the standard scope sits above what the retailer charges. If you are comparing quotes across sites, confirm the colour, the reticle and the mount before you conclude one shop is cheaper than another.

Price and value

One scope sits at around $260 and the other at around $500 , and the gap is wider than it looks once you add a mount. The Sig models sold here ship with a cantilever mount, a throw lever and fold-flat caps, so the price is genuinely all-in; Sig confirms the ALPHA-MSR mount, throw lever and lay-flat flip backs as included on the standard 1-6x24. The Strike Eagle includes a throw lever but no mount, so a quality one-piece cantilever adds to its own. One caveat worth carrying: the mount is not an automatic feature of the Tango MSR name, because Sig also sells the same scope as a no-mount SKU under its own part number. Check what is in the box rather than trusting the model name.

Both are selling under their makers' list prices, but not by the same margin. Vortex's list for the FFP Strike Eagle is a long way above its street price of around $500 ; the Sig sits much closer to its own list at around $260 , with the gray OPMOD kit as the outlier below it. For a new build watching the total, the Sig is the value default, and its 282 owner reviews at 4.6/5, more than any other LPVO in our guide, back that up.

Focal plane: the Strike Eagle's real advantage

The biggest difference between these two is not the extra 2x of magnification, it is the focal plane. The Strike Eagle is first focal plane, so its EBR-8 bullet-drop reticle grows and shrinks with the image and the holdovers stay accurate at any magnification. The Sig is second focal plane, so its BDC6 holds are calibrated at 6x and only exact there. For an LPVO that lives at 1x for speed and gets zoomed for the occasional longer shot, that SFP trade is reasonable at the price. If you actually use holdovers at varied magnifications, the FFP Strike Eagle earns its premium.

Reach, weight and handling

The Strike Eagle reaches 8x to the Sig's 6x, useful for identifying and holding on targets out toward 600 yards, and its illuminated dot-in-ring behaves like a red dot at true 1x. The cost is weight: at 23.9 oz it is over five ounces heavier than the 18.5 oz Sig, which shifts the balance of a light carbine. Be careful generalising that, though. The weight belongs to the first-focal-plane build rather than to the name: Vortex's other 1-8x24, the second-focal-plane AR-BDC3, weighs 17.4 oz, which is lighter than the Sig. Putting a reticle in the first focal plane is what costs you those ounces. Both have honest LPVO limits: usable but not daylight-nuclear illumination, and glass that softens at the top of the zoom range. Neither is a precision dialer; these are 1x-first speed optics that zoom when you need them.

Which one should you buy?

• First AR build or lowest all-in cost: Sig Tango MSR. The mount is in the box and it is the most-reviewed pick in our guide.
• Want holds accurate at every magnification: Strike Eagle, for the first focal plane reticle.
• Reach toward 600 yards for hogs or predators: Strike Eagle, for the extra 8x.
• Light carbine where balance matters: Sig Tango MSR, over five ounces lighter.
• Undecided and on a tight budget: start with the Sig; it outperforms its price, and you can move up later.
• Comparing prices across shops: match the SKU first. The Tango MSR 1-6x24 arrives here as five models that differ in colour, reticle, mount and bundle, and a cheaper quote is often a different scope.
• You came looking for a Strike Eagle 1-6x24: it is no longer in Vortex's line-up. The 1-8x24 above is its replacement.
