I bought another one, and it had specific instructions that closing the bold could damage the bore sighter. With that understanding, this item worked great for my 308 Win and 7mm-08 Rem. I would have given it a 5 if the instructions said not close the bolt on it. That would have saved me considerable time and trouble. --- ## 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.jp/products/149638659-midten-243-308-bore-sight-red-dot-boresighters-308-three](https://www.desertcart.jp/products/149638659-midten-243-308-bore-sight-red-dot-boresighters-308-three) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-07-12*
