Introduction: Why Scope Mounts Matter
A high-quality optic is only as good as the mount holding it in place. Whether you’re a precision shooter, hunter, or tactical operator, the right scope mount ensures stability, accuracy, and proper eye alignment. However, with so many options available—including one-piece mounts, cantilever mounts, two-piece rings, and more—choosing the best mount can be overwhelming.
Beyond mount types, factors like height, MOA cant, and material composition play a role in determining how well your optic performs. This guide will break down the different types of scope mounts, how to choose the right height, and what MOA cant means for your shooting setup.
Types of Scope Mounts
There are three primary types of scope mounts:
1. One-Piece Scope Mounts
One-piece mounts provide maximum rigidity and durability, making them a popular choice for precision rifles, long-range shooting, and AR-style platforms.
✅ Pros:
- Strong and stable, preventing scope shift from recoil.
- Often includes built-in MOA cant for long-range adjustments.
- Ideal for high-recoil firearms like .308 or .300 Win Mag.
❌ Cons:
- Heavier than other mounts.
- Can limit access to the rifle’s action on bolt-action rifles.
2. Cantilever Scope Mounts
Cantilever mounts are commonly used for AR-style rifles where proper eye relief is a concern. They extend the optic forward to ensure the correct positioning, especially for LPVOs (Low Power Variable Optics) and red dots with magnifiers.
✅ Pros:
- Perfect for AR-15 and modern sporting rifles.
- Provides optimal eye relief without needing additional rail space.
- Often includes built-in forward offset for better balance.
❌ Cons:
- Not typically used on bolt-action rifles.
- Slightly bulkier than traditional one-piece mounts.
3. Two-Piece Scope Rings
Two-piece scope rings are a classic choice for bolt-action rifles, offering lightweight flexibility and compatibility with different action lengths.
✅ Pros:
- Lighter than one-piece mounts.
- Allows easier access to the rifle’s action.
- More versatile for different rail and base configurations.
❌ Cons:
- Less rigid than a one-piece mount, which can affect long-range precision.
- More difficult to align properly, requiring extra care during installation.
Scope Mount Heights: Low, Medium, or High?
The height of your scope mount affects your cheek weld, eye alignment, and overall shooting comfort. Here's a breakdown of the most common heights:
- Low Mounts (0.8” - 1.1”) → Best for bolt-action rifles and precision shooting with smaller objectives (32mm or less). Keeps the optic close to the bore, reducing parallax issues.
- Medium Mounts (1.2” - 1.4”) → Great for hunting rifles and general-purpose scopes with 40-44mm objectives. Balances eye alignment with scope clearance.
- High Mounts (1.5” - 1.9”) → Designed for AR-15 and tactical rifles, ensuring proper alignment with stocks that have straight combs. Best for optics with 50mm+ objectives.
🔧 Pro Tip: If your optic sits too high or low, you may need to adjust your stock with a cheek riser for better consistency.
Understanding MOA Cant: 0 MOA vs. 20 MOA
What Does MOA Cant Mean?
MOA (Minutes of Angle) cant in scope mounts tilts the optic slightly downward, allowing the shooter to take advantage of more internal elevation adjustments in their scope.
- 0 MOA Mounts – Perfect for general-purpose rifles and hunting setups. Keeps the optic level with the bore, ideal for shooting at ranges under 600 yards.
- 20 MOA Mounts – Designed for long-range precision shooting. This cant compensates for bullet drop, allowing more adjustment for extreme distances (800+ yards).
🔧 Pro Tip: If you're using a high-powered scope with limited internal elevation, a 20 MOA mount helps you reach further distances without maxing out your turrets.
Material and Construction: Aluminum vs. Steel
- 6061-T6 Aluminum → Most modern scope mounts are made from aircraft-grade aluminum, offering lightweight strength without sacrificing durability. Popular brands like Aero Precision, Geissele, and Vortex use 6061-T6.
- 7075-T6 Aluminum → Even stronger than 6061, this material is found in premium-tier scope mounts like Radian and Nightforce.
- Steel Scope Mounts → Less common but extremely durable. Ideal for heavy-recoil calibers like .338 Lapua, where extra strength is needed.
🔧 Pro Tip: Aluminum mounts are the best choice for most shooters due to their strength-to-weight ratio, while steel is best for extreme-duty applications.
Choosing the Right Mount for Your Rifle
✔️ For AR-15s & Tactical Rifles → Cantilever mount or high-rise one-piece mount (1.5”+ height)
✔️ For Bolt-Action Rifles & Hunting Guns → Two-piece rings or low-profile one-piece mount
✔️ For Long-Range Shooting → 20 MOA canted mount for extended elevation range
When selecting a scope mount, always match the mount height to your rifle’s comb height and consider whether you need additional cant for long-range shooting.
Conclusion: The Right Mount Makes All the Difference
A reliable scope mount is essential for accuracy, stability, and long-term durability. Whether you're setting up a long-range precision rifle, a tactical AR-15, or a hunting rig, choosing the right mount ensures consistent performance and repeatable accuracy.
