Can this be fixed or is it just bad?** A: It is possible you have astigmatism. The easiest way to check is to take a picture of the reticle turned on, then look at the pic you just took. If it's clear then it's your eyes, if blurry, the unit is bad. Hope this helps. **Q: What magnifiers will work with this site? I know Sightmark will but would like to know if other brands would work** A: It is always best for alignment purposes that you stick to the same brand. Unless a third party is testing all combinations of brands and measuring them precisely, no one can say what works with what best. Most brand combinations will be close though. **Q: What is the purpose for the wire coming out of the battery cap?** A: It is there so you dont lose the battery cap **Q: Hows the durability when i comes to a 223 caliber does it stay sighted in after multiple uses?** A: I have a Sightmark Ultrashot M-spec reflex sight. It has night vision as well on mine and I absolutely love it! I zeroed it in when I first got it, and it still shoots true to this day! I paid $250 for the LQD version, but you can get the FMS for $200. They're worth every penny! I'll never use another sight fot my AR! They're both "Military spec" sights. That's why they're higher, but well worth it. You want have to buy another sight! ## Frequently Bought Together - Sightmark Ultra Shot R-Spec Reflex Sight - Bontok Single Picatinny Aluminum Accessory Rail Set 3 5 7 9 11 13 Slots with 13 T-Nuts & Screws, 6 Wrench-Rounded Corner - CVLIFE Bore Sight Laser 223 5.56mm/9mm/.243.308/12Gauge/7.62x39mm/.45acp Red Laser Bore Sighter with Batteries --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.uk/products/69601503-sightmark-r-spec-reflex-sight](https://www.desertcart.co.uk/products/69601503-sightmark-r-spec-reflex-sight) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-09-23*
