https://greyhive.com/videos/watch/73554f1f-ec18-47c0-9930-e94e6dae2958 Same optic, different emitter, $10 more. I put the Osight K Green head-to-head with the red K that's been living on my X-Macro — mounted on Bersa's new M2XI double-stack 1911 — to answer two questions: does green actually read faster, and does it fix the astigmatism smear? Full transparency: I have a relationship with Olight and they sent this optic out to check out. Nothing changes about how I do it here — if it's junk, I say it's junk, and Olight already knows I will. This is the 7th Osight I've run, so I've got a read on this line. What's covered: the full spec rundown, the side-loading battery Olight customers finally got (no re-zero on a battery swap), shake-awake and the low-battery triple-flash, my honest take on advertised battery-life numbers and how to actually check a carry optic, green vs red in real light — where green wins and the one scenario where red still beats it — the astigmatism verdict, whether a 6 MOA dot belongs on a 5-inch gun at all, and why the steel-framed M2XI gave me the best dot tracking I've had out of a K. 🔧 SPECS AT A GLANCE Osight K Green: 6 MOA green dot, 21x14mm window, RMSc footprint, 7075 aluminum, IPX6, ~1 oz 8 daylight + 2 night-vision settings, motion-activated (3-min auto sleep), low-battery warning Side-loading CR1620 battery — swap without dismounting or re-zeroing Fits: Bersa M2XI (factory cut, co-witnesses), P365 line, Glock 43X/48 MOS, Hellcat OSP, Shield Plus Price: $169.99 (about $10 over the red K) 🔗 LINKS Olight Osight K: https://amzn.to/4gkYiH1 Osight C vs K review: Osight SE review: Osight XR review: Stacked — our free peptide price & vendor intelligence tool (38 vetted vendors, 1,000+ listings tracked daily): https://stacked-hq.com Codes, parts lists and stuff: https://2apatriotranch.com Some links may be affiliate links, which support the channel at no cost to you. ⏱️ CHAPTERS 0:54 – Welcome + full transparency 2:02 – Seven Osights in: the track record 2:38 – Why the Bersa M2XI (factory cut, co-witness) 3:32 – The spec sheet 4:12 – The side-loading battery (finally) 5:00 – Real talk on battery-life numbers 5:28 – Best-in-class packaging (the screws rant) 6:16 – Why green?
