Strike Systems 3.5-10x50E Advanced Scope Variable Rifle Scope

The Strike Systems 3.5-10x50E Advanced Scope is a variable magnification scope designed for mid- and long-range airsoft, featuring a 50 mm objective lens and a 30 mm main tube. It suits shooters who want a ready-to-use solution with mounts included, without having to source separate components.

The variable magnification range from 3.5x to 10x covers different engagement scenarios with a single optic: at minimum power the field of view is approximately 195 cm at 100 metres, useful for dynamic situations or multiple targets; at maximum power it narrows to around 45 cm, focusing on a distant target with full available resolution. Parallax adjustment runs from 20 metres to infinity — a range deliberately matched to typical airsoft distances, where a scope calibrated for a real firearm would often remain out of focus. The adjustable eye relief between 66 and 79 mm lets you find a comfortable shooting position without losing the full field of view.

The red and green illuminated Mil-Dot reticle offers 5 brightness levels to suit ambient light conditions: at the highest setting it stays visible against bright backgrounds in daylight; in low light it can be dimmed to avoid washing out your vision. Power is supplied by a CR2032 battery, not included. Windage and elevation adjustments are tool-free, allowing you to zero the point of impact without interrupting a session. One trade-off to bear in mind: a second focal plane reticle — as fitted here — keeps correct Mil-Dot subtensions only at maximum magnification. At intermediate settings the reticle appears smaller relative to the target, and milliradian readings must be recalculated accordingly.

Key points

• The 50 mm objective gathers more light than smaller lenses, maintaining brighter images in low-light conditions.
• Parallax adjustment from 20 metres to infinity is calibrated to real airsoft engagement distances, eliminating parallax error at typical ranges.
• The red and green illuminated Mil-Dot reticle with 5 brightness levels lets you match luminosity to ambient light without swapping reticles.
• Variable magnification from 3.5x to 10x means you do not have to choose between close-range engagement and long-range shooting: one optic covers both scenarios.
• Included mounts (30 mm tube, 20 mm bases) allow immediate mounting with no additional purchases, sitting at a low profile on the rail.
