SIGHTRON SCOPE SI 4-12X40 – AO G2 MOA-20 MATTE

For shooters working at distance, a 4-12x variable magnification scope strikes the balance between close-range clarity and extended-range precision. The SI 4-12x40 delivers that versatility with a MOA-20 reticle built for tactical shooting. Whether you're setting up at a Fremont range or working through a FFL transfer in Sunnyvale, TacticCAL stocks the glass serious shooters depend on.

MOA Reticle and Field of View

The MOA-20 reticle gives you precise holdover marks without guesswork, crucial when elevation adjustments matter. At 4x magnification, you maintain a wide sight picture for moving targets or close work; crank to 12x and the reticle subdivisions sharpen for distant precision. The 14.8-inch tube length keeps weight manageable on hunting rifles and precision builds. Handling transfers through our private party transfer process is straightforward—bring your scope and optic mounting hardware, and we'll get you squared away.

Frequently asked questions

Can I use this scope on both hunting and tactical rifles?

Yes. The 4-12x magnification range and MOA-20 reticle work equally well on hunting setups and tactical platforms. The matte finish resists glare in variable light conditions across different shooting environments.

What does adjustable parallax mean, and does this model have it?

Adjustable parallax lets you dial out focus errors at specific distances. This Sightron SI model does not feature parallax adjustment, making it simpler to operate and maintain at typical hunting and range distances.

Does TacticCAL help with CA compliant firearms?

Yes — TacticCAL specializes in California-compliant handguns from the DOJ Roster and PC §32100 exempt single-action revolvers. TacticCAL is your gun shop San Jose in the Bay Area.
