Monstrum is the leading manufacturer of affordable, high-quality rifle optics and accessories, boasting over 15 years of experience in engineering and manufacturing scopes. Our optics are designed to provide superior performance in any environment, whether you're hunting in the woods or shooting at the range.

As the pioneer of DTC precision rifle optics, we continue to challenge the limits of quality and affordability. Our dedicated service department and California-based operations ensure customers receive the best support and products.

The Monstrum Guardian Series is the latest iteration from our previous line of second focal plane (SFP) rifle scopes. The Guardian 3-9x AO is a full-featured scope suitable for hunting, target shooting, or tactical use. It offers adjustable 3-9 times magnification, allowing you to target out to 600 yards and beyond.

An adjustable objective lens (AO) allows for sharper focus of the target image, elimination of parallax, and range estimation. The fully illuminated MOA reticle features MOA hashmarks for ranging information, with an inline dial-controlled brightness adjustment.

Precision 1/4 MOA/click windage and elevation adjustments, coupled with an integrated throw lever, provide smooth and controlled magnification adjustments. The scope's aircraft-grade 6061 aluminum body is sealed and nitrogen-charged, making it resistant to water and fog.

In addition to the 3-9x40 AO model, the Monstrum Precision Optics lineup includes several other options:

3-9x32 AO Rifle Scope: Featuring an illuminated rangefinder reticle and close to mid-range performance up to 400+ yards.

2-7x32 AO Rifle Scope: Equipped with an illuminated rangefinder reticle and close to mid-range capabilities up to 300+ yards.

3-12x42 AO Rifle Scope: Offering an illuminated mil-dot reticle and close to mid-range performance up to 500+ yards.

3-9x40 AO Rifle Scope: Boasting an illuminated MOA reticle and close to mid-range versatility up to 500+ yards.

All Monstrum Precision Optics scopes share common features, including:

  • Shock, water, and fog-proof construction
  • Illuminated reticles for low-light conditions
  • High-profile scope rings for easy mounting
  • Flip-up lens covers for protection

Whether you're looking to upgrade your hunting setup or seeking a reliable tactical scope, Monstrum's Precision Optics lineup has the perfect solution. Visit our store to explore the full range of products and find the scope that best suits your needs.
