AR15 LPVO Beginner User Guide

Published on January 13, 2021
Duration: 25:14

This guide covers Low Power Variable Optics (LPVOs) for the AR-15, detailing magnification choices based on range and the importance of daylight bright illumination. It explains the differences between Second Focal Plane (SFP) and First Focal Plane (FFP) reticles, and discusses reticle types like Mil-radian and MOA. Proper scope mounting height, leveling techniques, and zeroing procedures using ballistic apps are also addressed, along with advanced techniques like occluded shooting.

Quick Summary

For AR-15s, 1-4x LPVOs are suitable for 0-300 yards, 1-6x for 0-400 yards, and 1-8x or 1-10x for ranges beyond 500 yards. Higher magnification can impact low-light performance due to smaller exit pupils. FFP reticles scale with magnification for consistent holdovers, while SFP reticles are only accurate at max power.

Frequently Asked Questions

What is the recommended magnification range for LPVOs on an AR-15?

For AR-15s, 1-4x LPVOs are suitable for 0-300 yards, 1-6x for 0-400 yards, and 1-8x or 1-10x for ranges beyond 500 yards. Higher magnification can impact low-light performance due to smaller exit pupils.

What's the difference between First Focal Plane (FFP) and Second Focal Plane (SFP) reticles?

FFP reticles scale with magnification, keeping holdover points accurate at any power. SFP reticles remain the same size, meaning holdovers are only accurate at the scope's maximum magnification.

How important is scope leveling for an AR-15 LPVO?

Proper scope leveling is crucial for long-range accuracy. An unlevel scope will cause bullet impacts to deviate from the reticle's aim point, especially at distance, leading to significant errors.

What are the benefits of a 1.93-inch scope mount height over the standard 1.5-inch?

A 1.93-inch mount provides a more heads-up shooting posture, which can improve comfort and speed. It also offers better clearance for accessories like lasers and night vision devices mounted under the scope.
