American Defense Manufacturing AD-DELTA-C Cantilever Scope Mount Review

Let’s Dive into American Defense Manufacturing AD-DELTA-C Cantilever Scope Mount

The American Defense Manufacturing AD-DELTA-C Cantilever Scope Mount is a purpose-built solution designed to bridge the gap between high-powered optics and the unique demands of SCAR and AR platform rifles. This mount, crafted by American Defense Manufacturing, isn’t just another accessory; it’s an engineered component aimed at optimizing eye relief and providing a rock-solid foundation for precision shooting. With its 2-inch offset and 1.5″ optic centerline height, the AD-DELTA-C promises to unlock the full potential of your rifle and optic combination.

I was constantly struggling with proper eye relief on my SCAR 17S, particularly when using scopes designed for longer ranges. Existing mounts either placed the optic too far back, requiring an uncomfortable cheek weld, or lacked the robustness needed to withstand the recoil of the .308 cartridge. I yearned for a mount that offered both adjustability and unwavering stability.

The AD-DELTA-C arrived well-packaged, immediately showcasing its quality construction. The hard coat T3 Mil-Spec anodized finish on the 6061 T6 aluminum gave it a durable and professional feel. Its weight, while noticeable, felt reassuring, signaling a mount built to withstand serious use.

I considered mounts from LaRue Tactical and Bobro Engineering, both known for their quick-detach systems and robust designs. However, the American Defense Manufacturing‘s patented QD Auto Lock(tm) Lever system and its reputation for accommodating various rail systems ultimately swayed me. I was hoping it would solve the common problem of mounts not fitting tightly on some rails.

My first impression was excitement tempered with a touch of apprehension. I was excited by the potential to finally achieve optimal eye relief and consistency, but also wary about the mixed user feedback I had seen regarding the adjuster nut. I hoped the quality justified the price of $241.35.

Real-World Testing: Putting American Defense Manufacturing AD-DELTA-C Cantilever Scope Mount to the Test

First Use Experience

I initially tested the American Defense Manufacturing AD-DELTA-C Cantilever Scope Mount at my local shooting range, mounting it on my SCAR 17S with a Vortex Viper PST Gen II 3-15×44 scope. The weather was clear and sunny, providing ideal conditions for zeroing the scope. The range offered distances out to 300 yards, allowing for a thorough evaluation of the mount’s ability to maintain zero.

The mount performed admirably under these conditions. Once properly adjusted and tightened, the scope remained securely in place, with no noticeable shifting or movement. The QD Auto Lock(tm) Lever system was surprisingly easy to use.

I did encounter a slight issue with the adjuster nut initially, as it felt a bit stiff. However, after a few adjustments, it loosened up and functioned smoothly. The biggest relief was finally achieving the perfect eye relief for my SCAR setup!

Extended Use & Reliability

After several months of consistent use, including multiple range trips and a weekend-long training course in varying weather conditions, the American Defense Manufacturing AD-DELTA-C Cantilever Scope Mount has proven to be a reliable and durable piece of kit. I subjected it to heat, light rain, and dusty environments. The mount held zero consistently.

The hard coat anodized finish has resisted scratches and wear remarkably well, maintaining its original appearance. Cleaning is simple. A quick wipe down with a lightly oiled cloth is all it typically requires.

Compared to a cheaper mount I previously used, the AD-DELTA-C is a significant upgrade. The cheaper mount would lose zero after only a few rounds. The American Defense Manufacturing mount provides a far more stable and consistent platform.

Breaking Down the Features of American Defense Manufacturing AD-DELTA-C Cantilever Scope Mount

Specifications

The American Defense Manufacturing AD-DELTA-C Cantilever Scope Mount boasts several key specifications that contribute to its performance:

• Manufacturer: American Defense Manufacturing
• Gun Rail: Picatinny – Ensuring compatibility with a wide range of rifles.
• Fabric/Material: 6061-T6 Aluminum – Provides a balance of strength and weight.
• Offset: 2 inches – Crucial for achieving proper eye relief on AR platforms.
• Gun Make: AR Platform – Specifically designed for AR-15 and AR-10 rifles.
• Weight: 9 oz – Acceptable weight for a durable cantilever mount.
• Gun Model: AR-10, AR-15 – Versatile compatibility across AR platforms.

These specifications translate to a mount that is both robust and functional. The 2-inch offset is essential for those running larger scopes on AR-platform rifles. The 6061-T6 aluminum and T3 Mil-Spec Anodize finish ensure long-term durability and resistance to the elements.

Performance & Functionality

The American Defense Manufacturing AD-DELTA-C Cantilever Scope Mount excels at its primary function: providing a stable and consistent platform for mounting high-powered optics on AR-style rifles. It maintains zero exceptionally well, even under heavy recoil. The QD Auto Lock(tm) Lever system allows for quick and easy removal and reattachment of the scope.

Its strengths lie in its robust construction, precise machining, and user-friendly design. The only notable weakness is the occasional stiffness of the adjuster nut, which, while not a deal-breaker, requires some initial attention. The 1.5″ optic centerline height is ideal for co-witnessing with backup iron sights on many AR builds.

It mostly exceeds expectations. It provides a level of stability and consistency that cheaper mounts simply cannot match.

Design & Ergonomics

The American Defense Manufacturing AD-DELTA-C Cantilever Scope Mount features a well-thought-out design, constructed from high-quality materials. The 6061 T6 aluminum provides a solid foundation. The hard coat anodized finish gives it a professional and durable appearance.

The mount feels substantial in hand without being overly heavy. The horizontal rings are easy to access and tighten, ensuring a secure grip on the scope tube. Minimalist design reduces unnecessary bulk and weight.

The QD levers are intuitive to use. The adjustment mechanism, while potentially stiff initially, is straightforward once understood.

Durability & Maintenance

The American Defense Manufacturing AD-DELTA-C Cantilever Scope Mount is built to last. The high-quality materials and robust construction ensure it can withstand the rigors of regular use. Its T3 Mil-Spec anodized finish resists scratches, corrosion, and wear.

Maintenance is minimal. A quick wipe down with a lightly oiled cloth is usually sufficient to keep it clean and functioning properly. Its robust design suggests a long lifespan with minimal maintenance.

Accessories and Customization Options

The American Defense Manufacturing AD-DELTA-C Cantilever Scope Mount doesn’t come with many accessories. Its primary function is to provide a mounting platform.

It is compatible with a wide range of 30mm scopes from various manufacturers. Its Picatinny rail interface ensures compatibility with any AR-platform rifle with a Picatinny top rail.
Its 1.5″ centerline height is a standard dimension. Making it easy to calculate and select appropriate height iron sights for co-witnessing, if desired.
