This laser comes with a little reflective sticker to I guess help you see the laser from a distance or something but I came up with the idea of wrapping the laser with this sticker to act as a “filler” in the chamber and it worked perfectly now the laser fits nice and snug inside the chamber with no wiggled room ultimately centering the laser up perfect inside the chamber resulting in a more accurate bore sight to dial in your optic. Review: Super impressed. Same zero regardless of orientation in chamber - This is my 3rd 12 gauge bore sighter and the only one that has actually been accurate. Other brands were all several inches difference and several degrees off. This is the only one that held the same position as you rotated it in the chamber. Lined up perfect with my iron sights so I know my optic is dead on. Looks to be extremely high quality and really heavy for how small it is which tells me it's a lot higher quality than the other cheapo brands. Will buy more products from this manufacturer. ## Features - [MidTen Precision] 12 gauge laser bore sight is designed to provides a precise reference to zero-in your optic and iron sights so as to save your time and money.

I set a table up om one end of a tweleve foot room. Set and locked my rifle into a gun vice. Inserted the bore Laser into the chamber. With bore light show on the far wall I aligned my red dot on top of it. I did this with a 12 gauge pump, several .223 rifles and a 9mm carbine. All using different bore sights of course. At range everything was within two clicks or right on. I did adjust the .223 and 9 to shoot a little higher. Twelve gauge was right on for twelve feet, which is good range for a home shotgun. **Q: Does this one turn on when trigger is pulled or does it stay on all time once place in chamber?** A: The laser turns on when the batteries are inserted and the cap is screwed on. There is no switch. You won't want to pull the trigger when this is in the chamber, as the back of the boresighter is brass and likely won't react well to a firing pin strike. It works pretty well. Keep in mind you just use this to align your sights and then eject the round. To store it you unscrew the rear cap and remove the batteries. **Q: What do I need to bore sight a .410 shockwave?** A: a .45 long colt bore sight could possibly work since there are revolvers that can fire both .45lc and 410 ## Customer Reviews ### ⭐⭐⭐⭐⭐ Not accurate until you do this *by D***. on January 31, 2024* Very bright and high quality laser but fits a little loosely in the chamber of a shotgun so it’s not gonna be dead accurate when sighting in your optic.

No on/off but just unscrew the bottom a few turns to shut it off. Passed the rotate table to ceiling check test with flying colors. Just wish their .223 bore sight was as good as their shotgun sight. ## Frequently Bought Together - MidTen Bore Sight 12 Gauge Laser Boresighter Red/Green Dot Zeroing Laser Bore Sight with Extra Batteries - MidTen bore Sighting Laser 223 5.56mm/9mm 30-06/25-06/270 Laser Bore Sight Boresighter with Batteries - MidTen Bore Sight Laser .45acp 20-Gauge 7.62x54R Red Dot 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.de/products/466921516-midten-12-gauge-bore-sight-laser-red-green-dot-zeroing](https://www.desertcart.de/products/466921516-midten-12-gauge-bore-sight-laser-red-green-dot-zeroing) --- *Product available on Desertcart Germany* *Store origin: DE* *Last updated: 2026-09-05*
