The Cross Armory Stock Lock AR15/M4 Black 7075 Aluminum Made a Bold First Impression
Navigating the ever-changing landscape of firearm regulations can feel like traversing a minefield, especially for those of us residing in states with stricter laws like California and New York. That’s why, when I stumbled upon the Cross Armory Stock Lock AR15/M4 Black 7075 Aluminum, it immediately piqued my interest. Cross Armory claims this product offers a simple, non-permanent solution for achieving “featureless” compliance without sacrificing the adjustability of your stock.
I was tired of the clunky, uncomfortable fixed stocks that many companies offer as a solution. I needed something that would allow me to maintain a proper cheek weld and length-of-pull, while still adhering to the law. The promise of being able to lock my existing adjustable stock in place, rather than replacing it entirely, was incredibly appealing.
Upon unboxing, I was immediately impressed by the Cross Armory Stock Lock. The black 7075-T6 aluminum construction felt solid and robust, lending an air of quality to the small but crucial piece. The included Allen wrenches were a thoughtful touch, ensuring I had everything needed for installation right out of the box.
Compared to other fixed stock solutions I’ve used, the Cross Armory Stock Lock presented a significantly more streamlined approach. Instead of replacing the entire stock and buffer tube, this simply locks your existing adjustable stock in place. This was the deciding factor for me, as it preserved the ergonomics I was already accustomed to. My first impression was overwhelmingly positive; I felt like I had found a clever and well-engineered solution to a frustrating problem.
Real-World Testing: Putting Cross Armory Stock Lock AR15/M4 Black 7075 Aluminum to the Test
First Use Experience
My initial test of the Cross Armory Stock Lock occurred at my local shooting range. I installed the lock on my AR-15, securing my preferred stock position. Installation was surprisingly easy and took only a few minutes using the provided Allen wrenches.
The Cross Armory Stock Lock performed flawlessly, maintaining a rock-solid lockup throughout several hours of shooting. I put it through its paces with various drills, magazine changes, and rapid-fire exercises. There were no issues, no slipping, and no movement whatsoever. It functioned perfectly even when the firearm heated up.
Extended Use & Reliability
After several months of regular use, the Cross Armory Stock Lock continues to perform admirably. There are no signs of wear or tear on the aluminum lock itself, and the finish has held up exceptionally well, even after repeated exposure to cleaning solvents and lubricants. The lock remains securely fastened.
Maintenance has been minimal; a quick wipe down with a clean cloth is all that’s needed to keep it in good condition. Compared to my past experiences with other compliance methods, the Cross Armory Stock Lock has been significantly less hassle and far more reliable. This product is a significant upgrade from using a permanently fixed stock, which, in my experience, becomes very uncomfortable to shoot.
Breaking Down the Features of Cross Armory Stock Lock AR15/M4 Black 7075 Aluminum
Specifications
- Material: Machined from billet 7075-T6 aluminum. This ensures a high strength-to-weight ratio and excellent durability.
- Finish: Black finish. This provides corrosion resistance and a sleek, professional appearance.
- Compatibility: AR-15 style firearms. It’s designed for standard mil-spec buffer tubes.
- Installation: Attaches at any point on the buffer tube. This allows for customized length-of-pull adjustments.
- Included: Two Allen wrenches. This is a thoughtful addition, simplifying the installation process.
These specifications are crucial because they directly impact the functionality and longevity of the product. The use of 7075-T6 aluminum, renowned for its strength, guarantees that the Cross Armory Stock Lock can withstand the stresses of regular use without failure. The ability to attach it at any point on the buffer tube is a massive advantage, giving shooters the freedom to fine-tune their stock position for optimal comfort and control.
Performance & Functionality
The Cross Armory Stock Lock excels at its primary function: securely locking your adjustable stock in a fixed position. It’s easy to install, provides a rock-solid lockup, and doesn’t interfere with the normal operation of the firearm. The lock has proven incredibly durable during my testing.
The only potential weakness I can identify is that the locking mechanism relies on set screws. Over time, repeated tightening and loosening could potentially damage the threads, but this hasn’t been an issue for me. Overall, the performance and functionality of this item are top-notch.
Design & Ergonomics
The design of the Cross Armory Stock Lock is simple, yet effective. The minimalist profile doesn’t add unnecessary bulk or weight to the firearm. The solid construction and precise machining inspire confidence.
The installation process is straightforward. The lock can be easily attached and adjusted, even by those with minimal gunsmithing experience. There’s practically no learning curve.
Durability & Maintenance
Given its 7075-T6 aluminum construction, the Cross Armory Stock Lock is built to last. Regular cleaning and inspection should ensure years of reliable service. The black finish has proven to be quite resistant to scratches and wear.
Maintaining the Cross Armory Stock Lock is as simple as periodically checking the set screws to ensure they are properly tightened. A drop of thread locker could be applied to the screws for added security. I anticipate this product will last for many years with proper care.
Accessories and Customization Options
The Cross Armory Stock Lock itself doesn’t require any additional accessories for its primary function. It is designed to work seamlessly with existing AR-15 buffer tubes and adjustable stocks. The fact that it does not require any specific proprietary parts is a major selling point.
The lock is compatible with various brands of adjustable stocks, providing flexibility for users who already have a preferred stock. It could be combined with a compliant pistol grip or muzzle device to create a completely “featureless” AR-15. This is essential for compliance in restrictive states.
