AR15 LPVO Beginner User Guide

Published on January 13, 2021
Duration: 25:14

This guide provides a comprehensive overview of Low Power Variable Optics (LPVOs) for the AR-15 platform, drawing on the expertise of Paul from SuperSetCA. It covers critical aspects such as selecting the right magnification for your engagement range, understanding the importance of daylight bright illumination and Field of View (FOV), and differentiating between First Focal Plane (FFP) and Second Focal Plane (SFP) reticles. The guide also details scope mounting options, proper leveling techniques, ballistic data acquisition using tools like chronographs and apps like Strelok, and advanced shooting methods like occluded shooting and the use of offset red dots.

Quick Summary

For AR-15 LPVOs, choose magnification based on range: 1-4x for up to 300 yards, 1-6x for up to 400 yards, and 1-8x/1-10x for 500+ yards. FFP reticles are accurate at all magnifications, while SFP holdovers are only accurate at max power. A 100-yard zero with ballistic app data is recommended.

Frequently Asked Questions

What magnification range is recommended for an AR-15 LPVO?

For AR-15 LPVOs, magnification is typically chosen based on engagement range. A 1-4x is suitable up to 300 yards, a 1-6x up to 400 yards, and a 1-8x or 1-10x for distances beyond 500 yards. Higher magnification can reduce exit pupil size in low light.

What is the difference between FFP and SFP reticles on an LPVO?

First Focal Plane (FFP) reticles scale with magnification, keeping holdovers accurate at any power. Second Focal Plane (SFP) reticles remain constant in size, meaning holdovers are only accurate at the maximum magnification setting.

How do I properly zero an AR-15 with an LPVO?

A 100-yard zero is generally recommended for LPVOs. It's crucial to gather accurate ballistic data (BC and velocity) using a chronograph and use a ballistic calculator app like Strelok to determine holdovers for longer distances.

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

A 1.93-inch scope mount height, compared to the standard 1.5 inches, allows for a more heads-up shooting posture, which can improve comfort and speed. It also provides clearance for accessories like lasers or night vision devices mounted on the rail.
