ACM’s SpecterDR-style optic copies the look of the well-known military gunsight. This version is a 1x non-magnified sight with a 40mm objective lens, which gives a large, bright picture and a forgiving eye box when you are moving.
The reticle lights up in red or green at several brightness levels, so you can match it to an indoor arena or a bright woodland field. It also has windage and elevation dials, backup iron sights on top, and a dual-lever mount for 20mm rails.
Key Features
- 1x non-magnified view – fast target pick-up at any range
- 40mm objective lens – a bright, wide sight picture
- Red and green illuminated reticle – several brightness levels for indoor and outdoor light
- Windage and elevation dials – zero to your rifle
- Backup iron sights on top – a fallback if the battery runs flat
- Dual-lever quick-release 20mm mount – fast on and off
Real-World Use Cases
The 1x setting suits CQB and woodland alike, letting you shoot with both eyes open while the reticle stays on target.
It is also a strong cosmetic upgrade for M4 and SCAR builds where the SpecterDR look fits a military loadout.

UK Legal & Site Notes
Optics are accessories, not imitation firearms, so no UKARA or other defence is needed to buy this scope. Check the mount suits the rail on your rifle before ordering.
Zero the optic on the rifle you will use it with, using your usual BB weight and at the range you most often shoot. Use the lowest brightness you can see clearly, which saves battery and avoids glare at dusk, and take the battery out if you are storing the optic for a long time.
