🎯 How to Choose the Right AR-15 Scope Mount

Selecting the perfect AR-15 scope mount isn’t just about price — it’s about fit, performance, and durability. Here’s what matters:

📌 1. Cantilever vs Straight Mounts

• Cantilever Mounts: Extend your scope forward to achieve proper eye relief on flat-top AR-15 receivers. Ideal for LPVOs and tactical optics.

• Straight Mounts: Rarely used for AR-15s unless running extremely compact optics.

📌 2. Quick Detach (QD) vs Fixed Mounts

• QD Mounts: Fast optic changes with minimal zero shift. Perfect for mission versatility.

• Fixed Mounts: Slightly lighter, simpler, and often a bit more rigid for precision builds.

📌 3. Tube Size Compatibility

• 30mm Scope Mounts: Standard for most tactical and LPVO scopes.

• 1-inch Scope Mounts: Common on hunting optics.

• 34mm Mounts: Emerging trend for long-range, high-end glass.

📌 4. Mount Height for AR-15s

• 1.5-inch centerline height (Lower 1/3 co-witness): Most common for modern AR-15s.

• Absolute co-witness height (1.41 inches): For those preferring a slightly lower optic alignment.

📚 AR-15 Scope Mount Buyer's Guide

When selecting a mount, consider:

• Recoil Management: Robust clamping systems prevent optic shift under rapid fire.

• Material: 7075-T6 aluminum preferred for its strength-to-weight ratio.

• Rail Compatibility: Ensure true Picatinny compatibility for secure lockup.

• Return-to-Zero: Especially critical for QD mounts — top brands guarantee minimal shift.

💡 Pro Tip:
Always torque your AR-15 scope mount to the manufacturer's specs and use blue threadlocker for long-term durability.

❓ Frequently Asked Questions (FAQ)

Q: What is the best scope mount height for an AR-15?
A: A 1.5-inch centerline height is the standard for AR-15 optics, providing comfortable cheek weld and sight alignment.

Q: Should I use a cantilever mount for my AR-15?
A: Yes. Cantilever mounts ensure proper eye relief, especially when running scopes with longer eye boxes like LPVOs.

Q: What’s better — QD or fixed mounts for AR-15s?
A: QD mounts offer fast optic changes and flexibility, while fixed mounts are slightly lighter and potentially more rigid for long-range shooting.

Q: Can a 30mm scope mount fit a 1-inch tube?
A: No. Always match your scope tube diameter to the correct mount size (30mm tube = 30mm rings).
