I'm going to be using it to shoot an electronic target that will beep when I hit it.** A: that wont work with this. I have no idea about the range, but the black battery box that hangs off to the side has a cable attached to the part that inserts into the chamber. you push it in with you finger while the rifle is held in position on a bench. if you try and hold it free hand, the cable is going to wobble, and the will make the laser wobble, and...well I think you see where I'm going. I guess you could try and rig something up, but I don't think there would be any consistent accuracy. this is a laser boresighter, for setting up a scope. it is not trigger activated. think of using a sword in an archery contest. **Q: will this work in my glock 23? 9mm** A: No it will not, a glock 23 is a 40 s&w bullet, unless you converted it to a 9mm with a barrel swap and this product still wont work in a 9mm **Q: Will this work for a .22 magnum?** A: The laser bore sight itself is shaped just like a .22LR and extracts when you cycle the bolt via the extractor. So if the only length/dimension difference is forward of battery....I would think it should. Hope that helps. Don't have any .22 magnums. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by L***O on April 2, 2015* ### ⭐⭐⭐⭐⭐ Review *by H***E on September 22, 2025* ### ⭐⭐⭐⭐ Review *by M***. on September 15, 2025* ## Frequently Bought Together - Sightmark RimFire Brass Boresight with Red Laser - Sightmark Centerfire Boresight with Red Laser - MidTen bore Sighting Laser 223 5.56mm/9mm 30-06/25-06/270 Laser Bore Sight Boresighter 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.dk/products/1154723-sightmark-rimfire-brass-boresight-with-red-laser](https://www.desertcart.dk/products/1154723-sightmark-rimfire-brass-boresight-with-red-laser) --- *Product available on Desertcart Denmark* *Store origin: DK* *Last updated: 2026-05-03*
