About scoperanker
The biggest number on a rifle scope is the one that takes light away from you: 22 of the 53 scopes in this catalog hand your eye a beam narrower than 2.5 mm at their top magnification, and not one of them prints that figure on the box. It is objective diameter divided by magnification, it takes two seconds to work out, and nobody works it out standing at a counter. So this site works it out for every scope it lists, next to the specification it came from.
What the tube does not tell you
A 5-25×56 and a 5-25×50 sit next to each other on the rack looking like the same decision. Wind both to 25× at last light and one is passing 2.2 mm of beam to your eye and the other 2 mm, which is the difference between a usable sight picture and hunting for your own eyebox. The same arithmetic decides whether the 35× on a long-range scope is magnification you will ever use or a number for the advertisement. Every scope page here carries that figure at both ends of the zoom range, the twilight factor at the top, and the click value converted into inches on a target at 100 yards — the form in which a turret actually means something.
The other thing the sheet leaves out is a common axis. A scope is sold in minutes or in mils and the two camps do not cross-shop easily, so every travel and click figure in this catalog is restated in the other unit at 3.4377 MOA per milliradian. A 20 MIL elevation scope and a 70 MOA one can then be ranked against each other, which is what a shooter picking a base actually needs.
How scopes are sorted, and where the specs come from
Each scope carries one category out of 6 — LPVO, Hunting, Long Range, Precision / Tactical, Rimfire, Crossbow — assigned on what the optic is built to do rather than on the marketing line, because makers file the same 4-16×50 under three different headings. Beyond that the catalog is faceted on the things buyers filter by and argue about: focal plane, turret unit, tube diameter across 4 sizes, and 20 spec features from true 1× to zero stop.
The specifications themselves were read off manufacturers’ own product pages and spec-sheet PDFs, and each entry records where its figures came from — 34 distinct sources across 53 scopes. Several makers block automated requests to their own product pages, so a handful of entries were built from major retailers’ listings and the maker’s manual instead; where that happened the source note on the scope says so, and where a product page and a spec-sheet PDF disagreed the PDF was used and the conflict recorded. Nobody here has mounted these scopes. There is no lab, no tunnel, no box test, and the site never suggests otherwise — how we compare sets out the whole method.
There is no owner-sentiment section, on purpose
Comparison sites usually bolt a “what owners say” block onto every page, filled by whoever was loudest in public. Owner discussion is worth reading, but reading it properly for 53 scopes is work that has not been done here, and a summary of discussion nobody actually read is the most quietly dishonest thing on the internet. So the short lists on each scope page are headed on paper, and they mean it: they are drawn from that scope’s own published figures — a 36-ounce weight, a fixed 100-yard parallax, 20 MIL of total elevation. If a sentiment section ever appears here it will name where the sentiment came from, in the same way the specs name their source today.
The same rule retires the star rating. All 53 scopes carry a null rating, no page renders stars, and no page emits rating markup, because an aggregate score is a claim about real owners and this catalog has none it can cite. Every list on the site instead names the specification it is ordered by.
The four fields makers routinely omit
A field nobody publishes stays empty rather than getting a plausible number. As of the current catalog that means 44 scopes show no country of origin, 22 with an adjustable parallax show no minimum focus distance, 4 publish no windage travel, and 2 publish no overall length. Those gaps are visible on the page as gaps. Estimating them would make the tables prettier and the site worse, and a reader comparing two scopes deserves to know which of them the maker declined to describe.
Prices are the other honest blank. Each one is a hand-recorded snapshot shown with a “~”, never scraped live, because a scope’s price moves with rebates and changes with the reticle you pick. The 4 price bands survive a sale in a way the number does not.
Who runs it, and why nothing is for sale
Two people, working on this in their own time. No office, no staff of reviewers, no editor, and nobody with a title. The site carries no retailer links and no affiliate tags of any kind, so no optics company has ever sent money, a demo scope or an email that changed a line here — there is nothing for a brand to buy. That is not a virtue being advertised; it is just the reason the ordering can be pure arithmetic. Funding and data handling are set out on the privacy page.
Sweeps, not a live feed
The catalog was last checked end to end on 2026-09-20 (September 2026), and that date is what the footer, the sitemap and the dataset markup all read from — no page here claims to have been updated today because it was rebuilt today. Between sweeps, scopes get added when a model is worth comparing and dropped when a maker discontinues it; several models that were meant to be in the launch catalog turned out to be retired and were left out rather than listed from memory. Corrections go in as soon as they are confirmed against a source.
