With a mount height of \u003cstrong\u003e27,3 mm\u003c\/strong\u003e and an optical centreline at \u003cstrong\u003e35,76 mm\u003c\/strong\u003e from the rail axis, it positions the red dot at lower 1\/3 co-witness with the iron sights of an AR-style rifle, keeping the backup sights visible without obstruction.\u003c\/p\u003e\u003cp\u003eThe cantilever profile shifts the optic \u003cstrong\u003e68 mm\u003c\/strong\u003e towards the shooter relative to the fixing point on the Picatinny rail: a practical advantage on rifles with a long handguard or when mounting the red dot further forward on the upper rail of the castle nut. The QD mechanism allows tool-free removal and remounting with repeatable zero return, provided the lever is locked with consistent torque each time — the trade-off inherent to quick-detach that a fixed screw mount does not require.\u003c\/p\u003e\u003cp\u003eThe low weight of \u003cstrong\u003e74 g\u003c\/strong\u003e has negligible effect on the overall balance of the rifle.
