Quick Summary
The APLUSGEAR 90 Degree Hinged Backup Iron Sights are a foldable sight set with red and green fibre optic aiming points, a tool-free curved visor and a flip-up design. The rear sight and front sight are both adjustable by hand, and the set is described as compatible with most Picatinny rails.
It is built for buyers who want a compact backup sighting option with manual adjustment and rapid flip-up action. The key purchase checks are rail compatibility and whether the red and green fibre optic layout matches your preferred sight picture.

What to Compare Before Buying
- Rail compatibility: This set is described as compatible with most Picatinny rails. Check that your rail matches before choosing an offer.
- Sight picture: The front uses a red fibre sight and the rear uses a green fibre sight. Compare that layout with the aiming picture you prefer.
- Adjustment method: Both sights adjust by hand. Confirm that manual adjustment suits your setup.
- Flip-up format: The 90 degree hinged, spring-loaded design changes how the sights sit when not in use. Check that this format suits the way you mount and store the rifle.
When to Consider a Different Option
Consider a different sight set if you need confirmed compatibility with a rail system other than Picatinny, or if you want a sight that does not rely on hand adjustment and flip-up positioning.
Before You Decide
Confirm the rail type on your firearm, check that the red and green fibre optic sight picture suits your preference, and make sure the flip-up hinged format matches your mounting setup.
