Frequently Asked Questions
Is the 2.5-10x42 Mark 4HD first or second focal plane?
It is a second focal plane (SFP) scope, so the TMR reticle stays a constant visual size while holdovers are true at maximum magnification.
What are the turret adjustments?
M5C3 ZeroLock turrets (0.1 MRAD clicks, three-revolution elevation), giving 24.7 MIL / 85 MOA of elevation travel with a positive return to zero.
Is the reticle illuminated?
Yes. The TMR reticle is illuminated with Motion Sensor Technology that puts the sight into standby after five minutes of inactivity and wakes it instantly on movement, running on a CR2032 battery.
What rings or mount do I need?
It uses a 30mm maintube. See our scope mounts & rings in the matching diameter.
Is it covered by warranty?
Yes — the optic is backed by Leupold's Full Lifetime Guarantee; the illumination electronics carry Leupold’s electronics warranty.
