Faster Sight-In Starts Here: Boresight Before You Burn Ammo
Mounting a new scope, swapping optics, changing rings, or adjusting your setup can easily turn into a frustrating “where did my shots go?” session—especially at longer distances. A laser boresight helps you:
Get on paper quickly at close range
Reduce wasted ammunition during initial zeroing
Speed up optic alignment after installs or changes
Confirm point-of-aim vs. point-of-impact shifts before live fire
For hunters getting ready for season or shooters who frequently change optics, boresighting is one of the easiest ways to save time and range resources.
Multi-Caliber Compatibility: .7mm / .264 / .338
This model is designed specifically for .7mm, .264, and .338 caliber rifles—covering a wide variety of popular cartridges. That makes it a great choice for shooters running calibers commonly associated with:
Flat-shooting hunting setups
Long-range capable builds
Versatile “do-it-all” rifles that span deer to larger game cartridges (cartridge-dependent)
Always match the boresight to your rifle’s bore/caliber for best alignment and consistency.
Red Laser Visibility: Clear Reference for Setup and Adjustment
A red laser gives you a clear aiming reference for aligning your optic before firing live rounds. This helps you make meaningful adjustments sooner by:
Establishing a clear “starting point” for windage/elevation
Reducing the amount of guesswork during initial scope alignment
Helping you confirm alignment after transport or gear changes
Making it easier to set up at home before you head to the range
It’s an efficient way to begin the zeroing process with more confidence.
Brass Construction: Durable Fit and Consistent Alignment
The brass body is built for repeated use and consistent insertion/fit. Brass is a common material choice for boresighting tools because it offers:
Solid durability for frequent use
Consistent fit characteristics and stable alignment
A rugged, field-friendly feel that holds up in gear bags
Reliability when you’re boresighting multiple rifles or helping friends set up optics
When consistency is the goal, a sturdy housing helps maintain repeatable results.
Includes Battery Pack and Carrying Case: Ready to Travel, Easy to Store
This kit includes a battery pack and a carrying case, making it easy to keep everything organized and protected. That’s ideal for:
Range bags and hunting packs
Gunsmith benches and tool drawers
Travel to camps or out-of-town matches
Keeping small accessories from getting lost
A dedicated case means your boresight stays protected and ready when you need it.
Perfect for Scope Installs, Re-Zeroing, and Seasonal Checks
The Sightmark SM39004 is especially useful for:
New scope installations and ring swaps
Reconfirming alignment after bumps, travel, or storage
Switching between optics on the same rifle
Seasonal pre-hunt zero checks
Range days where you want to get productive quickly
It’s a practical tool that supports better consistency and reduces frustration.
Ideal for Hunters, Precision Shooters, and DIY Rifle Builders
Whether you’re a casual hunter or a dedicated shooter, boresighting helps you start smarter. This tool is great for:
Hunters who want fast sight-in before season
Precision shooters who frequently tune or test setups
DIY builders who mount their own optics
Anyone who wants to minimize wasted rounds and range time
A boresight doesn’t replace live-fire zeroing—but it gets you close faster and makes the final step much easier.
