Great price for 3 different bore sights. Super easy to use and made sighting in my pistol super quick and easy. ### ⭐⭐⭐⭐ The 45acp boresighter will not seat in my XDE barrel *by D***E on September 11, 2023* The lasers are bright, but the 45acp foresight will not allow my XDE to fully go into battery. This causes a slight upward can't to the barrel and a resulting inaccurate laser dot down range. ## Frequently Bought Together - Bayattoo Bore Sight 9mm/.40 S&W/45ACP/223REM Laser Sight Red Dot Boresighter with 9pcs Batteries - MidTen bore Sighting Laser 223 5.56mm/9mm 30-06/25-06/270 Laser Bore Sight Boresighter with Batteries - EZshoot Bore Sight 243 308/223 5.56mm/ 9mm/12-Gauge Red Laser Boresighter with Extra 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.jp/products/423350680-9mm-40s-and-w-and-45acp-laser-boresighter-kit](https://www.desertcart.jp/products/423350680-9mm-40s-and-w-and-45acp-laser-boresighter-kit) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-09-06*
