Scope note: THE ONLY RECORD IN THE DIRECTORY WHOSE MEASUREMENTS ARE NOT THE MANUFACTURER'S. Shadow Systems publishes no dimensions, weight or capacity anywhere — its MR920 pages carry a feature description and nothing else, checked on both the current product page and the 2020 model landing page (read via Web Archive; shadowsystemscorp.com serves a Cloudflare challenge to direct fetching, which this directory does not attempt to defeat). Recorded on a user decision (2026-08-12) that a lower-tier dimension set is acceptable for an explicitly named configuration. The configuration is the standard MR920 with a 4 in non-threaded barrel, black polymer frame and a 15-round magazine — the gun American Rifleman reviewed hands-on. Threaded, Elite, Foundation and Combat variants are separate listings under the base-model rule. Provenance differs by field and every value is tier-labeled on the page: dimensions, weight, capacity, barrel and sights are EDITORIAL, from that review; the trigger pull and warranty are MANUFACTURER. Two disclosures about the lower-tier evidence. First, the retailer listings corroborate overall length, weight and capacity exactly, but Grice attaches the same 7.125 in overall length to a 4.5 in THREADED variant, which cannot be true of both guns — retailers here are evidently repeating one spec sheet across configurations, so their agreement is weak corroboration and the recorded figures follow the review's 4 in gun only. Second, overall width is unrecorded: no source that could be loaded publishes it, and the search-result figure of 1.25 in was never traced to a page. The trigger pull is Shadow Systems' own published 4.5–5.0 lb range, read from the MR920 Elite SS-1012 listing since that is the only reachable manufacturer page — it may not hold across trims, and the review's independently measured 4 lb 13 oz falls inside it but is a measured value the source policy forbids recording. Action type is unrecorded: Shadow Systems describes none, and the review's "recoil-operated" describes the operating system where this directory's other records use ignition type (striker-fired, SAO), so recording it would put two different axes in one column. Warranty is 5 years and fully transferable, read from a 2019 capture because the live warranty page is challenged too — re-check before relying on it. All imperial-only, so every metric value is converted and flagged.

Verification boundary: Published technical data are rounded, may not reflect manufacturing tolerances, and may change without notice. MSRP is not recorded: most cited product pages do publish a price, but it changes without notice and independently of the specification, so this directory has no field for it and the row stays blank rather than carrying a figure that would silently go stale. Values marked ≈ were converted by this directory from the unit system the source published; the unmarked figure in the same row is the published one.

Evidence tiers backing this record: Manufacturer, Retailer / distributor, Editorial. Unmarked values come from manufacturer documentation; any value drawn from a lower tier is labeled inline with that tier. Where two sources disagreed, the higher tier was recorded and the disagreement noted.
