Buyer’s Guide
Choosing the right one piece scope mount involves considering several factors that directly impact your rifle’s performance and your shooting experience.
Material and Construction
Most quality one piece scope mounts are made from 6061 or 7075 aluminum for a balance of strength and weight. Look for CNC machining for precision and hard-anodized finishes for durability and corrosion resistance. A rigid unibody design is generally preferred over multi-piece constructions for holding zero.
Offset and Cantilever Design
Cantilever mounts extend forward, providing more flexibility for achieving proper eye relief, which is crucial for a comfortable and consistent shooting position, especially on rifles like the AR-15. Inline mounts offer a direct ring-to-ring connection, often for shorter action rifles or specific shooting styles.
Scope Tube Diameter and Ring Spacing
Ensure the mount’s ring diameter matches your scope tube (e.g., 1 inch, 30mm, 34mm). Ring spacing is also important; too close and it might not fit longer scopes, too far and it might not offer enough adjustment. Check the center height relative to your rifle’s rail.
Mounting System and Rail Compatibility
Most modern mounts attach to a Picatinny rail. Look for secure locking mechanisms, like robust bolts or quick-release levers, that prevent movement under recoil and ensure the mount holds zero reliably. Some mounts feature integrated accessory rails for additional gear.
Weight and Overall Profile
While rigidity is key, excessive weight can affect rifle handling. Many manufacturers use lightening cuts and advanced alloys to reduce weight without compromising strength. Consider the overall profile and how it integrates with your rifle’s ergonomics.
Who Should Buy What
For AR-15 platforms and those needing flexible eye relief, cantilever mounts like the Monstrum Slim Profile or Vortex Sport are excellent choices. If you need to mount accessories, the DISCOVERYOPT Heavy Duty or Burris AR-P.E.P.R. offer integrated solutions. For maximum weight savings, Monstrum’s Deadlock series is a strong contender.
What To Avoid
Avoid mounts with flimsy construction or those that don’t securely lock onto your Picatinny rail, as these are prone to shifting and losing zero. Also, be wary of mounts with incompatible ring diameters or those that don’t provide adequate clearance for your scope’s objective bell or eyepiece.
How These Products Compare
The reviewed mounts range from ultra-lightweight designs like the Monstrum Deadlock to robust, accessory-ready options like the DISCOVERYOPT and Burris P.E.P.R., offering varied solutions for different shooter needs and rifle platforms.
Dialing in Your Eye Relief
When choosing a one piece scope mount, pay close attention to the offset and ring spacing. These dimensions directly impact your eye relief, which is crucial for a comfortable and consistent shooting position, especially on platforms like the AR-15.
Frequently Asked Questions
What is the advantage of a one piece scope mount?
A one piece scope mount generally offers superior rigidity and alignment compared to two-piece mounts. This integrated design minimizes potential flex or misalignment between the rings, which helps in maintaining a consistent zero under recoil and ensures the scope is perfectly aligned with the rifle’s bore.
How do I choose the right height for my scope mount?
The ideal height depends on your rifle and scope. For flat-top AR-15 platforms, a 1.5-inch to 1.7-inch center height is common for 1-inch scopes, allowing comfortable cheek weld. Larger scopes or specific shooting styles might require higher mounts. Always check for clearance between the scope’s objective bell and the rifle’s handguard.
What does 'cantilever' mean for a scope mount?
A cantilever scope mount extends forward from its base, positioning the scope rings ahead of the mounting point on the rifle’s rail. This design is particularly useful for rifles with limited mounting space or when needing to achieve optimal eye relief for the shooter.
Are lightweight scope mounts durable enough?
Many modern lightweight one piece scope mounts are constructed from high-strength alloys like 6061 or 7075 aluminum and feature smart design elements like lightening cuts. While they may not be as heavy as steel mounts, they can be incredibly durable and are often preferred for their reduced impact on rifle balance.
