Coverage, as published

Lifetime coverage on the optic. The published policy reads: "If your Osight product (including its structure, built-in battery, LED, or lens) ever experiences any issues, we promise to take care of it. If we are unable to repair your product, we will promptly replace it with a product in perfect working condition, which will be of equal or better physical condition." Osight states it warrants all products "that exhibit any defects in material and workmanship under normal use." Accessories are tiered separately on the same page: Optics = Lifetime Warranty; Charging Cover and Charging Cable = 1-Year Warranty; Screws, Lanyard, Tool and Cleaning Cloth = No Warranty. Returns are separate from the warranty: "You have the flexibility to return your order for any reason within 30 days from the date of receipt."

Exclusions, as published

Per the policy page: "this LIFETIME WARRANTY does not cover loss, theft, deliberate damage, or cosmetic damage." The FAQ states the same list slightly more broadly, adding misuse and normal wear: it "excludes coverage for loss, theft, misuse, deliberate damage, or normal cosmetic wear and tear. Additionally, accessories such as cables, screws, and cleaning cloths have limited or no warranty." Nothing in either published text addresses transferability to a second owner, proof of purchase, or product registration, so none of those is recorded as a requirement here.

Manufacturer support

Osight is an active US-market brand with its own store, current in-stock SKUs and a US service address: 4330 W Chandler Blvd, Suite 4, Chandler, AZ 85226, cs.us@osight.com. Claims go through the maker's site: "Warranty claims are submitted through our website Warranty and Repair - Osight with product details, a description of the issue, and photos. Our team reviews and processes the claim promptly." No numeric turnaround is published anywhere, so none is recorded. Third-party purchases are routed differently: "For items purchased from third-party platforms within the last 30 days, we recommend reaching out to the original seller for assistance. If you fail to get contact with the original seller, contact us."

Documented failure modes

  • Osight SE (RMSc enclosed): water ingress through the front lens during 30-minute submersion . Enough water entered the enclosed optic to stop the emitter projecting a reticle. The tester notes his own earlier drop testing may have caused the leak. DISPUTED: a second tester submerged a different, undropped unit for the same 30 minutes and it stayed dry (Dan Zimmerman, Shooting News Weekly).
  • Osight SE (RMSc enclosed): reticle died under heat at roughly 120 degrees F . Heated with a hair dryer to about 120F, below the claimed 140F upper operating limit, and the reticle went out. Single tester, single unit; no other tester ran a heat test.
  • Osight SE (RMSc enclosed): battery-tray retention screw backs out during shooting . "The screw tends to get loose and exit the gun while shooting"; the tester's own screw loosened after testing. Two spare screws ship with the optic. The same failure mode is documented for the Holosun EPS Carry, so it is a category pattern rather than an Osight-only defect.
  • Osight SE (RMSc enclosed): test unit died permanently after the water and heat sequence . The same tester as the Pew Pew Tactical review, writing later: the first unit "suffered through a lot of my durability testing, but ultimately leaked water into the design and eventually shut off, to never come on again". One unit, after deliberate abuse; the second unit he tested was not durability-tested.
