🔧 Why Choose a Prism Scope for Your AR-15?

✔️ Astigmatism-Friendly – Unlike red dots, etched reticles are always sharp, even for those with vision issues
✔️ Battery Optional – Reticle is visible without power thanks to glass etching
✔️ Rapid Targeting – Fixed 3x–5x magnification for fast shots at 0–300 yards
✔️ Compact & Durable – Built to survive recoil and harsh field conditions
✔️ Red or Green Illumination – Adapt to lighting conditions instantly

A prism scope bridges the gap between a red dot and a variable optic—perfect for home defense, competition, or law enforcement.

❓ Frequently Asked Questions

Q: What is a prism scope?
A: A prism scope uses a fixed glass prism instead of a multi-lens system, allowing for compact size and an etched reticle that remains visible even without illumination.

Q: Are prism scopes good for astigmatism?
A: Yes. Because the reticle is etched into the glass, prism optics don’t blur or flare like red dots often do for people with astigmatism.

Q: Can I use a prism scope for CQB?
A: Absolutely. A 3x prism scope with a bright reticle and wide field of view is excellent for close-range engagement.

Q: Do prism scopes need batteries?
A: No. The etched reticle is always visible, but most models include illuminated options for use in dark environments.

Q: What's better—prism scope or red dot?
A: For users with astigmatism or those needing some magnification and BDC, prism scopes offer better clarity and flexibility.
