How to Properly Mount an Optic on Your Spandau Arms S2 Shotgun for Turkey Season

As turkey season approaches, many hunters are looking to fine-tune their setups and maximize confidence in the field. One of the most popular upgrades for today’s turkey shotguns is adding an optic for faster target acquisition and improved precision.

If you’re running a Spandau Arms S2 Shotgun, properly mounting your optic is an important step that should never be rushed. Correct hardware, proper torque, and thread preparation can help ensure your optic stays secure when it matters most.

Below are a few simple tips to help you install your optic the right way.

1. Use the Correct Mounting Screws

The Spandau Arms S2 Shotgun uses:

• M4 x .70 thread pitch screws

Depending on the optic, mounting plate, or rail you’re using, screw length may vary. In most cases, 4mm to 5mm is common, but always verify fitment for your specific setup.

Pro Tip:

Before final installation, remove the barrel and inspect the inside of the receiver to make sure screws are not protruding excessively. If needed, screws may require trimming so they sit as close to flush as possible without interfering with internal function.

2. Torque Screws to Proper Specification

One of the most common mistakes when mounting optics is over-tightening screws.

We strongly recommend using a torque wrench and following the optic or mount manufacturer’s specifications.

General Recommendation:

• Typical torque range: 12–15 inch-pounds
• Do not exceed 18 inch-pounds

Using the correct torque helps prevent stripped threads, damaged hardware, or movement under recoil.

3. Prepare the Threads Correctly

Before installing screws, always inspect threaded holes for:

• Dirt
• Carbon buildup
• Metal shavings
• Oil or lubricant residue

Clean threads thoroughly and degrease both the screws and mounting surface before applying thread locker.

This helps thread locker bond properly and can significantly improve long-term retention.

4. Allow Thread Locker to Cure

After installation, allow your thread locker adequate time to cure before use.

Best Practice:

• Let it sit overnight whenever possible
• Always follow the thread locker manufacturer’s directions

Rushing straight to the range after installation may compromise the hold before the compound has fully set.

Why Proper Optic Installation Matters

Turkey hunting often means early mornings, changing weather, and long walks into the woods. The last thing you want is a loose optic or shifting zero when a bird finally steps into range.

Taking a few extra minutes during setup can save frustration later and help ensure your Spandau Arms S2 Shotgun is ready when the moment comes

Final Thoughts

Whether you’re preparing for opening day or simply upgrading your setup, proper optic mounting is one of the easiest ways to build confidence in your equipment.

We wish everyone the best of luck this turkey season—and hopefully none of us get outsmarted by a bird that ends up selling for $1.19 a pound during the holidays.
