Instantly transform your 1× reflex or 1× prism sight into a versatile 3× optic with the Delta Hornet Compact Magnifier ×3 — one of the shortest, most compact magnifiers on the market for fast-moving field use

It can be mounted for instant change from 1x to 3x magnification and is compatible with all Red Dot Sights, as well as Holographic sights and 1x Prism Scopes.

• 3× Fixed Magnification:
  Boosts your existing red dot or 1× prism scope from 1× up to 3× for improved target clarity and precision at extended ranges.

• Compact & Lightweight Package:
  Among the smallest and most portable magnifiers available — easy to install and manoeuvre without adding excessive bulk.

• Flip-to-Side Mount:
  Quick-release side fold mount lets you move the magnifier out of the way when you want to shoot at 1× without removing it.

• Wide Compatibility:
  Works with most red dot sights, holographic sights and 1× prism scopes mounted at the same optic height.

• Tool-Free Focus Adjustment:
  Built-in diopter and azimuth adjustment makes it easier to centre the optics and achieve sharp image focus without tools.

• Nitrogen-Filled & Weather-Sealed:
  Sealed housing prevents internal fogging and keeps dust and moisture out, maintaining clarity in the field

• Compatible with Right or Left-Hand Configuration:
  Flip mount supports ergonomic ambidextrous use — flip-to-side for either hand preference.
  
  

Mounting & Compatibility Notes

• Designed to be used with red dot sights, holographic sights and 1× prism optics mounted at the same height. No special footprint is required beyond a standard accessory rail spacing.

• The flip-to-side mount lets you rapidly move the magnifier out of alignment when not needed.

• Because different rifles and optics have slight height variations, you may want to confirm co-witness / sight height when pairing with a red dot (e.g., 1/3 vs absolute co-witness) — proper rail and riser heights can help align the magnifier pipe to your dot.
