Putting the DoubleStar Push Button Folding Stock Mechanism w/o Boss to Work
My quest for a reliable folding stock mechanism led me to the DoubleStar Push Button Folding Stock Mechanism w/o Boss. This particular component addresses a critical need for firearms enthusiasts who value compactness and versatility without compromising on security. For years, I’ve wrestled with aftermarket stocks that either felt flimsy or required cumbersome manipulation to secure. The allure of a positive, mechanical lock in both open and folded positions, coupled with the ability to choose folding direction, was too strong to ignore. My initial impression upon unboxing was one of solid craftsmanship; the 6061-T6 Aluminum construction felt robust, and the black finish was pleasingly uniform. While I briefly considered simpler, friction-based hinges like those from Stormwerkz, the desire for a definitive click and lock pushed me towards this more substantial option. A sense of anticipation, mixed with a healthy dose of critical assessment, accompanied my first look at this mechanism.
Real-World Testing: Putting DoubleStar Push Button Folding Stock Mechanism w/o Boss to the Test
First Use Experience
My testing ground for this folding mechanism was primarily my home workshop and a local shooting range. I first integrated it into an AK platform build, a common application for side-folding stocks. The initial installation was straightforward, fitting neatly between the stock and receiver block as advertised. I tested its functionality across three different AK variants, each sporting a distinct billet stock from separate manufacturers. The mechanism performed admirably, cycling smoothly and locking with a satisfying audible and tactile confirmation. Even when experimenting with a pig nose adapter paired with an AR buffer tube and stock, the adapter performed well.
Conditions ranged from controlled workshop environments to the dustier, more dynamic setting of the range. Repeatedly opening and closing the stock throughout a range session, I encountered no issues with stiffness or resistance. The positive lock in both the open and closed positions was consistently reliable, a significant upgrade from previous experiences with less secure mechanisms. My only initial observation was a slight amount of play when fully extended, a nuance I noted but didn’t find immediately detrimental.
Extended Use & Reliability
After several months of intermittent but regular use, the DoubleStar mechanism has proven its mettle. It has endured countless folds and unfolds, simulating the practical demands of storage, transport, and quick deployment. The initial slight play in the open position, while still present, hasn’t degraded into anything more concerning. I found that applying a bit of rubberized grip tape on the interior of the hinge assembly effectively mitigated this minor wobble, providing a more solid feel when shouldered.
The durability of the 6061-T6 Aluminum construction is evident; despite minor cosmetic scuffs from handling and occasional contact with other gear, the core functionality remains uncompromised. Cleaning is a simple affair – a quick wipe-down with a dry cloth or a mild solvent is usually sufficient, followed by a light application of lubricant on the pivot points. Compared to some budget folding adapters I’ve used in the past, which developed significant wobble after just a few hundred cycles, this unit from DoubleStar feels built to last. Its robust construction inspires confidence, especially when compared to friction-based systems that can loosen over time without regular adjustment.
Breaking Down the Features of DoubleStar Push Button Folding Stock Mechanism w/o Boss
Specifications
The DoubleStar Push Button Folding Stock Mechanism w/o Boss comes with a set of specifications that highlight its robust construction and thoughtful design. It’s primarily constructed from 6061-T6 Aluminum, a material chosen for its excellent strength-to-weight ratio, making it durable yet reasonably light. The mechanism measures 3.75 inches in length and weighs in at 5.5 oz, making it a substantial but not overly burdensome addition to a firearm. Designed for Rifle platforms, its primary function is to serve as an intermediary between the stock and the receiver block.
The standout feature is its positive lock in the open and closed position, a critical aspect for safety and reliability. This lock-up is engaged and disengaged via a precisely placed push-button. Furthermore, its ambidextrous capability is a significant advantage, as it can be mounted to fold either right or left, offering users flexibility based on their preferred shooting stance, optics setup, or even personal carry style. The black finish provides a utilitarian and professional aesthetic that blends well with most firearm platforms.
Performance & Functionality
The core job of the DoubleStar Push Button Folding Stock Mechanism w/o Boss is to provide a secure and repeatable folding stock solution. In this regard, it largely excels. The positive lock in both positions is a standout feature. When the stock is deployed, it clicks into place with a definitive sound and feel, offering a reassuring solidity. Similarly, when folded, the lock engages firmly, preventing accidental unfolding.
The push-button operation is intuitive and requires deliberate action to disengage the lock, minimizing the chance of accidental folding. While the open lock-up is exceptionally firm, as noted by some users, there can be a slight amount of play present in the folded position. This minor looseness is not enough to compromise safety for most applications, but it might be a point of concern for those seeking absolute rigidity in all states. Compared to purely friction-based folding mechanisms, which can sometimes drift or require constant tightening, this mechanical lock offers a more dependable experience.
Design & Ergonomics
The design of this folding mechanism is a blend of utilitarian functionality and understated robustness. Crafted from 6061-T6 Aluminum, it feels solid and well-machined, with no sharp edges or rough surfaces. The black finish is matte and durable, resisting minor abrasions and fingerprints reasonably well. The push-button actuator is well-positioned for easy access, even when wearing gloves, and its recessed design helps prevent accidental activation.
Ergonomically, the mechanism is designed to be unobtrusive. Its 3.75-inch length ensures it doesn’t add excessive bulk to the firearm’s profile, especially when folded. The ability to mount it for folding to either the left or right side is a brilliant design choice that caters to a wide range of users. While the mechanism itself is the focus, its integration with various stock types and adapters proved generally seamless, though the specific feel and handling are inherently tied to the stock being used.
Durability & Maintenance
Based on my experience and the materials employed, the DoubleStar Push Button Folding Stock Mechanism w/o Boss is built for durability. The 6061-T6 Aluminum is known for its resistance to corrosion and fatigue, suggesting a long service life under typical operational stresses. The internal locking mechanism, being mechanical rather than reliant on friction or detents, should theoretically maintain its positive engagement for thousands of cycles.
Maintenance is straightforward. A light application of a good quality lubricant on the pivot points and the push-button assembly is generally all that is required. Cleaning involves wiping away dust and debris, ensuring the locking mechanism remains free of grit that could impede its smooth operation. I have not encountered any specific failure points in my testing, but prolonged exposure to extreme elements or harsh impacts would be the primary concern for any metal component. The inclusion of a set of screws with the mechanism suggests that secure installation is paramount for its long-term performance.
Accessories and Customization Options
The DoubleStar Push Button Folding Stock Mechanism w/o Boss is essentially a core component, and as such, it doesn’t come with a wide array of accessories. However, it does include a set of screws necessary for its installation, which is a practical inclusion. The primary “customization” aspect lies in its ability to be mounted for folding to either the right or left side. This flexibility is a significant design advantage, allowing users to tailor the folded profile to their specific needs.
While not included, the mechanism is designed to interface with standard stock mounting solutions, such as receiver blocks or adapters. This opens up a vast world of aftermarket stock options, from traditional skeleton stocks to more modern brace-style setups. Compatibility with other brands’ receiver blocks is generally good, though a perfect fit is often achieved when paired with DoubleStar‘s own receiver blocks. Users might also consider adding small amounts of grip tape or other shims internally to further refine the lock-up in the folded position if even the slightest play is unacceptable.
