DoubleStar Ambi-Safety Selector M16 Review

Everything I Learned from the DoubleStar Ambi-Safety Selector for M16

The DoubleStar Ambi-Safety Selector for M16 promises to offer enhanced control and accessibility for both left- and right-handed shooters. DoubleStar aims to provide a drop-in replacement that allows seamless operation from either side of the rifle, which is a significant advantage in tactical scenarios or for shooters with specific needs. My initial interest stemmed from a desire to improve the ergonomics of my AR-15, specifically to provide better ambidextrous capabilities for drills and training.

I was looking for a safety selector that provided a positive, tactile feel without being overly aggressive or obstructive. Upon receiving the DoubleStar Ambi-Safety Selector for M16, I immediately noted the black phosphate finish and the distinct lever design. It appeared robust, but I had some initial concerns about the small screw securing the left-side lever.

Compared to a standard mil-spec safety selector and a Geissele Super Configurable Safety, the DoubleStar offered a more streamlined left-side lever. I chose this option over the Geissele because I was looking for something lower profile for a specific build. My first impression was cautiously optimistic; it looked good, but the proof would be in the installation and function.

Real-World Testing: Putting DoubleStar Ambi-Safety Selector for M16 to the Test

First Use Experience

My primary testing ground for the DoubleStar Ambi-Safety Selector for M16 was at my local outdoor shooting range. I incorporated the selector into several drills focused on transitions and weak-side shooting. During initial testing, the selector performed adequately in dry conditions.

However, I noticed some gritty resistance when switching between safe and fire. Despite this, the ambidextrous functionality proved helpful, especially during left-handed drills. The shorter left-side lever did prevent accidental engagement, which was a plus.

Extended Use & Reliability

After about a month of regular use, I continued to experience the same gritty feeling when manipulating the selector. The phosphate finish showed no signs of wear, but the overall feel remained less than ideal. Cleaning and lubrication helped minimally, suggesting the issue was related to the internal machining.

The 8620 steel construction appeared durable, but the smoothness of operation was lacking compared to higher-end selectors I’ve used. While it functioned reliably in terms of physically switching the firearm between safe and fire, the user experience was subpar. It ultimately disappointed me given my expectations for a more refined feel, and I ended up swapping it out for a different ambi selector.

Breaking Down the Features of DoubleStar Ambi-Safety Selector for M16

Specifications

The DoubleStar Ambi-Safety Selector for M16 boasts the following specifications:

• It is manufactured by DoubleStar.
• The color is black.
• The finish is phosphate coated.
• It is designed for the M16 platform.
• The material is 8620 Steel.
• It is an ambidextrous design.
• The design incorporates a shorter left-side lever secured by a 1/16 hex head screw.

These specifications are important because they dictate the selector’s durability and compatibility with the M16 platform. The 8620 steel construction provides a robust foundation, and the phosphate coating enhances corrosion resistance. The ambidextrous design is crucial for versatility, and the shorter left-side lever aims to minimize interference with right-handed shooters.

Performance & Functionality

The DoubleStar Ambi-Safety Selector for M16 performs the core function of switching between safe and fire, but the overall experience is compromised by its rough action. While it reliably engages and disengages the safety, the gritty feel detracts from its usability. The strength lies in its ambidextrous design and the low-profile left-side lever.

However, the primary weakness is the lack of smoothness in operation; it doesn’t meet the expectation of a high-quality, refined safety selector. Improvements are needed in the machining and polishing of the internal components.

Design & Ergonomics

The design of the DoubleStar Ambi-Safety Selector for M16 is functional, prioritizing ambidextrous use and minimizing interference. The use of 8620 steel provides a solid feel, but the phosphate coating doesn’t contribute significantly to the ergonomics. The user-friendliness is hampered by the gritty action, creating a slight learning curve as one gets accustomed to the feel.

Build quality is decent, though the finish shows no immediate signs of wear, the internal roughness is a concern. While I can appreciate the concept, the final product needs some refinement.

Durability & Maintenance

Given the 8620 steel construction, the DoubleStar Ambi-Safety Selector for M16 is likely to last a reasonable amount of time under normal use. The phosphate coating offers good corrosion resistance, potentially extending its lifespan. Maintaining the selector is relatively simple, requiring occasional cleaning and lubrication.

However, the gritty action may accelerate wear on internal components over time. The durability of the small hex screw securing the left-side lever is also a potential concern, requiring careful tightening to avoid stripping.

Accessories and Customization Options

The DoubleStar Ambi-Safety Selector for M16 does not come with any additional accessories. It is designed as a drop-in replacement for a standard M16 safety selector and is compatible with most standard AR-15/M16 lower receivers. There are no specific customization options beyond the inherent ambidextrous functionality.

However, users may choose to pair it with aftermarket grips or other lower receiver components to further enhance ergonomics. The simplicity of the design limits customization, focusing instead on providing a functional ambidextrous solution.
