The light was bright and accurate. ### ⭐⭐⭐⭐⭐ Great product *by K***Y on October 30, 2025* Works great. Would prefer to be able to turn it off without having to take the batteries out. ### ⭐⭐⭐⭐ Gets you within 8" at 50 yards *by R***L on August 24, 2020* I picked this up for my AR10 308 win I just picked up and had to sight the rifle in over the past weekend. Easy enough to use the boresight as just insert the batteries and place the laser in the barrel. Outside the laser is too weak to be visible more than a few feet away so I initially went inside and got about a 50' span to line up my scope to the laser dot. Not much length but best I could do. I then went outside and took a shot at 50 yards. I was actually fairly impressed I got to around 8-10" of the target - I was expecting to be further off honestly for a $8 boresight laser. A few tweaks to the scope and was in business. It aint perfect but it gets you to the paper target to then fine tune your scope or iron sights for accuracy. I'd buy again. --- ## 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.no/products/149638659-243-308-laser-boresighter](https://www.desertcart.no/products/149638659-243-308-laser-boresighter) --- *Product available on Desertcart Norway* *Store origin: NO* *Last updated: 2026-09-22*
