Introduction To Shotgun Scopes

    The 12 gauge shotgun might be the most versatile firearm in existence today. Many of us have a 12 gauge shotgun that we use for home defense, hunting, sporting, or other applications, but we're still using the factory open sights.

    Maybe you've thought about getting an optic for your shotgun, but aren’t sure what the first step should be?

    The world of shotgun optics can be confusing, but don't fear! We're here to help you decide which scope is best suited to your needs.

    Below you will find reviews of shotgun different optics, one of them is sure to be perfect for you.



    If you’re in a hurry, here’s a cheat sheet:

    The Nikon Slughunter BDC 200 is the ideal scope for using on a 12 gauge shotgun shooting slugs. 

    How to Choose the Best Scope for Your Needs

    • Purpose
    • Budget
    • Brand


    The first step in deciding what optic to buy for your shotgun is answering a simple question - what primary purpose does my 12 gauge shotgun serve?

    Whatever role your 12 gauge is filling is going to be a huge factor in deciding what optic to purchase. A fast targeting red dot for home defense is not going to be idle for deer hunting or shooting slugs at long distances.

    Similarly, if you're using a 12 gauge shotgun with an 18" barrel for home defense, you probably aren't using that same shotgun to turkey hunt with. Maybe you've got a lightweight semi-automatic model for shooting sporting clays, or a high end tactical model for three gun competitions.

    Unlike some other weapons platforms, a 12 gauge isn't going to fill more than one role typically. This makes optic selection a bit easier since the primary purpose of the shotgun is quite clear.

    The Nikon has 5" of eye relief to protect the shooter against even the strongest of recoil. The scope lenses have been fully multicoated. This gives the shooter a clear and bright sight picture while reducing glare, aiding in targeting and accuracy.

    The combination of 3-9x variable zoom and 1/4 MOA windage and elevation adjustments allow for excellent accuracy and even the longest of ranges. The BDC 200 crosshair has aiming points, allowing for quick adjustments to compensate for distance and slug-drop.

    For close range, tactical, and home defense shotgun applications you don't need something with variable zoom, you need something to get you on target quick. One of the most popular red dots on the market today is the Bushnell Trophy Red Dot.

    The Bushnell Trophy is a 1x power (no zoom) compact red dot sight with a 25mm objective lens. The red LED is 3 MOA, big enough to see and aim quickly without being too overpowering. A built in mount attaches directly to any top-rail, eliminating the need for other mounts or scope rings.

    The Trophy red dot can be used in any lighting condition thanks to its 11 brightness settings. It is powered by a single CR 2032 battery. The body of the red dot is waterproof to protect against the elements, and shockproof to withstand all types of recoil. The internals of the sight have been nitrogen filled to stop internal fogging.

    The unlimited eye relief lets the user mount it anywhere on their shotgun that they find comfortable. The red dot weighs only 3.7 ounces, adding performance to your shotgun without adding a ton of bulk.

    For any sort of situation where speed is key, the Trophy Red Dot will be a great companion.
