ACM 558 Scope with Red and Green Holographic Sight (Black)

The ACM 558 is a holographic style reflex sight built for fast shooting in CQB and at mid range. The large rectangular window lets you aim with both eyes open, so you keep your view of what is going on around you.

A CNC-machined aluminium hood protects the composite inner housing from knocks and bad weather. The circle-dot reticle can be lit in red or green with a dedicated switch, and the push buttons give several brightness levels. The quick-detach lever mount clamps straight onto a 20mm Picatinny rail.

Key Features

• Holographic style 1x sight – wide window for both-eyes-open aiming
• Red or green circle-dot reticle – switch colour with a toggle
• Push-button brightness – multiple levels for indoor and outdoor light
• Aluminium protective hood – over a high-impact composite housing
• Quick-detach lever mount – fits 20mm Picatinny rails
• Multi-coated glass – anti-reflective and scratch resistant

Real-World Use Cases

The 558 suits fast-moving games, from CQB sites to woodland, where you need to put the dot on target quickly rather than take careful long shots. The circle-dot pattern makes it quick to find the centre.

The QD lever mount makes it easy to move between rifles, so it works as a sight you take from one build to the next.
