DoubleStar Ambi-Safety Selector for M16 Review

Reviewing the DoubleStar Ambi-Safety Selector for M16: Beyond Marketing

As an equipment specialist with over a decade immersed in demanding environments, from dusty workshops to the meticulous sterility of labs and the unpredictable nature of field use, I approach gear with a healthy dose of skepticism and a keen eye for practical application. The DoubleStar Ambi-Safety Selector for M16 caught my attention not for flashy marketing, but for its straightforward promise: enhanced operational flexibility for a platform many of us rely on. My quest for this particular component stemmed from a desire to achieve a more authentic build on an M4A1 clone, aiming for that precise aesthetic that often dictates the choice of specific parts, even if their functional benefit is nuanced.

First impressions were mixed. The concept of an ambidextrous safety is, of course, a well-established enhancement for modern firearms, offering a crucial advantage in adaptability. Upon unboxing, the DoubleStar Ambi-Safety Selector for M16 felt solid. Machined from 8620 Steel and finished with a phosphate coating, it presented a robust, utilitarian appearance. However, the initial feel hinted at potential friction points, a subtle premonition of what extended use might reveal. I had considered a few other aftermarket selectors, some with more aggressive knurling or unconventional lever designs, but the DoubleStar offered a balance of traditional aesthetics and the core ambidextrous functionality at a competitive price point. My initial reaction was one of cautious optimism, tempered by a seasoned understanding that true quality is revealed not in the initial handling, but through consistent, real-world application.

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

My testing regimen for this component involved integration into a dedicated M4A1 clone build, subjected to the rigors of a simulated operational environment. This meant countless cycles of engaging and disengaging the safety during dry fire drills, transitions from various shooting stances, and even handling the rifle with gloves on, simulating conditions where fine motor control might be compromised. I also subjected it to a fair amount of bench time, cycling it repeatedly to break it in and assess any initial resistance.

The initial installation itself was straightforward, provided one possesses the correct tools, specifically a 1/16 hex head screw driver. The selector slid into place, and the detents engaged with a distinct, audible click, which initially felt promising. However, even within the first few hundred cycles, a peculiar sensation began to emerge: a gritty, almost gravelly feel when moving the selector between positions. This was particularly noticeable when transitioning from the “Safe” position to “Fire” or “Semi.” It was a distinct departure from the smooth, buttery action one might expect from a well-machined firearm component.

First Use Experience

My testing primarily took place in a controlled environment – my workshop and dedicated range area. I focused on repetitive manual manipulation, as well as integrating it into simulated shooting drills. The primary goal was to assess how the ambidextrous functionality performed under pressure and how the tactile feedback felt during critical moments.

The DoubleStar Ambi-Safety Selector did perform its core function of providing an accessible lever on both sides. For a right-handed shooter, the shorter left-side lever proved manageable, requiring a deliberate but not overly cumbersome shift of the index finger to disengage. However, the aforementioned grittiness persisted, creating a tactile sensation that felt less like precision engineering and more like something requiring a bit of grit removed. This was certainly a surprise; I had anticipated a clean, crisp operation, and the “gravelly” feel was an unexpected quirk.

Extended Use & Reliability

After several weeks of consistent use, accumulating thousands of dry-fire cycles and integrating it into live-fire sessions, the initial concerns regarding the tactile feel haven’t entirely vanished, but they have somewhat mellowed. The selector still operates, and the detents maintain their positive engagement, but that internal roughness is a constant reminder of its mechanical nature.

In terms of durability, the 8620 Steel construction and phosphate coating have held up admirably. There are no visible signs of wear on the levers or the body where it interacts with the receiver. It hasn’t shown any tendency to loosen or exhibit lateral play, which is a testament to the design’s ability to maintain a solid lockup. Maintenance has been minimal, as one would expect for a component like this; a quick wipe-down during general firearm cleaning is all that’s been required. Compared to the basic, mil-spec selector I replaced, this ambidextrous unit offers a functional upgrade, albeit one with a slightly less refined feel.

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

The DoubleStar Ambi-Safety Selector for M16 is a component designed to enhance the ergonomics and usability of the M16 platform, allowing for manipulation from either side of the firearm. This is achieved through its dual-lever design, catering to a wider range of shooter preferences and situations.

Specifications

• Manufacturer: DoubleStar
• Color: Black
• Finish: Phosphate Coated
• Gun Model: M16 (compatible with AR-15/M4 platforms)
• Fabric/Material: 8620 Steel
• Hand: Ambidextrous

These specifications translate into a product that is built to withstand the rigors of firearm use. The 8620 Steel is a robust material commonly used in firearm components for its strength and durability, ensuring longevity. The phosphate coating provides a layer of corrosion resistance and a non-reflective finish, crucial for tactical applications. The ambidextrous nature is its primary selling point, allowing for quick safety engagement and disengagement regardless of the shooter’s dominant hand or shooting position.

Performance & Functionality

The primary function of the DoubleStar Ambi-Safety Selector for M16 is to provide a positive means of selecting fire modes, specifically Safe, Semi-Automatic, and in the case of a select-fire M16, Auto. It undeniably achieves this. The detent system is strong and ensures that the selector stays firmly in its intended position.

However, the performance is marred by an inconsistent feel during manipulation. The transition between Safe and Semi, and particularly Semi and Safe, has a distinctly rough, gritty texture. This isn’t a functional failure in terms of safety engagement, but it detracts significantly from the overall user experience, making the operation feel less polished than expected. While it works, it doesn’t feel as refined as some premium alternatives I’ve encountered.

Design & Ergonomics

The design centers around the ambidextrous levers. The longer, standard-profile lever is on the right, while a shorter, more stubby lever is positioned on the left. This shorter lever is intended to prevent interference for a right-handed shooter’s thumb while maintaining accessibility.

In practice, this ergonomic choice works reasonably well. For a right-handed shooter, the shorter left lever is indeed less likely to snag on clothing or gear, yet it’s still accessible enough for a quick flip with the index finger or thumb. The grooved interface for the 1/16 hex head screw that secures the smaller lever also appears robust, promising a secure attachment. The overall build quality feels solid, indicative of the 8620 Steel construction.

Durability & Maintenance

The durability of the DoubleStar Ambi-Safety Selector for M16 appears to be a strong suit, largely due to its 8620 Steel construction and phosphate coating. I have observed no signs of premature wear, chipping, or significant marring, even after numerous manipulations and exposure to the general grime of a workshop environment.

Maintenance is as simple as it gets for this type of component. It requires no lubrication beyond what’s applied to the rest of the fire control group during routine cleaning. The design doesn’t present any intricate areas prone to trapping debris that would necessitate specialized cleaning procedures. Potential failure points, if any, would likely stem from the detent spring or plunger, but with the solid lockup observed so far, this seems unlikely in the short to medium term.

Accessories and Customization Options

This specific product, the DoubleStar Ambi-Safety Selector for M16, is primarily a standalone replacement part. It does not typically come with any additional accessories. The primary “customization” is the inherent choice to install an ambidextrous selector over a standard one.

Compatibility is key here; this selector is designed for the standard AR-15/M16 lower receiver and fire control group. While not explicitly stated, it’s a safe assumption that it adheres to standard dimensions, meaning it should interface correctly with most aftermarket triggers or trigger guards designed for the platform.

Pros and Cons of DoubleStar Ambi-Safety Selector for M16

Here’s a breakdown of the advantages and disadvantages based on my hands-on experience:
