Modern Sporting Rifle Customization & Performance Upgrades

Maximize Your Rifle's Potential

At Rock River Tactical, we specialize in transforming standard Modern Sporting Rifles (MSRs) like the AR-15, AK-47, and magazine-fed tactical pistols into precision tools customized for your mission, sport, or defense needs. As a Veteran-Owned FFL Gunsmith in Southern Wisconsin, we provide the technical expertise and attention to detail that only comes from real-world experience.

Don't trust your high-value optics and critical components to guesswork. We use professional-grade tools and industry best practices to ensure every upgrade enhances performance, reliability, and safety.

Professional Optic Installation & Bore Sighting

We eliminate the guesswork, ensuring your scope or red dot is mounted securely, level, and ready for the range.

Service Details:

- Scope & Red Dot Mounting: We properly lap rings, ensure correct eye relief, and use manufacturer-specified torque for a reliable, repeatable setup, utilizing quality tools like Wheeler Fat Wrenches.

- Bore Sighting & Preliminary Zero: Your new optic will be professionally bore-sighted, drastically reducing the number of rounds needed for final zeroing.

- Compatibility Check: Full assessment of your rifle's rail system and chosen optic/mount combination.

- We install all popular brands: Trijicon, EOTech, Aimpoint, Vortex, Leupold, and more.
