Manticore Arms Scorpion EVO Slider Stock Review

Deep Dive into the Manticore Arms Scorpion EVO Slider Stock

For those who appreciate the classic lines and robust functionality of the MP5A3 telescoping stock, the Manticore Arms Scorpion EVO Slider Stock offers a compelling, modern interpretation for the CZ Scorpion EVO platform. As an experienced gear specialist, I’m always on the lookout for upgrades that blend form with function without compromising reliability. This particular stock, inspired by an iconic design, promised a significant aesthetic and ergonomic improvement over the standard offerings for my CZ Scorpion 3 Plus. My search for a stock that wouldn’t interfere with the ejection port when collapsed, a common issue with some folding designs, led me directly to this Manticore Arms offering. Initial impressions upon unboxing revealed a solid, well-machined piece of hardware, immediately suggesting a quality build. While I briefly considered some of the more budget-friendly polymer options, the allure of steel construction and the classic MP5 look was too strong to resist, sparking a sense of anticipation for how it would perform.

Real-World Testing: Putting Manticore Arms Scorpion EVO Slider Stock to the Test

First Use Experience

My initial testing of the Manticore Arms Scorpion EVO Slider Stock took place on the range and during dry-fire drills in my workshop. The stock’s design is intended to mimic the familiar MP5A3 telescoping stock, and its deployment and retraction feel familiar, albeit with a slightly different tactile feedback. I specifically tested its functionality across various shooting positions, focusing on how it felt when shouldered, both in its collapsed and extended states. The primary concern was ensuring unobstructed ejection, which this stock successfully addressed even in its most compact configuration, a stark contrast to some folding alternatives I’ve used. There were no immediate issues, though a very slight stiffness was noted during the initial deployment, which I attributed to the tight tolerances of new components.

Extended Use & Reliability

After several weeks of consistent range trips and regular handling of my CZ Scorpion, the Manticore Arms Scorpion EVO Slider Stock has proven to be remarkably robust. Despite numerous cycles of extending and collapsing the stock, it has maintained its positive lock-up in both open and closed positions, showing no signs of premature wear. Its steel construction feels reassuringly solid, and it has endured the typical environmental variables encountered at the range without any degradation in performance. Maintenance has been minimal; a light application of gun grease on the slide rails, as recommended for such telescoping mechanisms, has kept it operating smoothly. Compared to some flimsy plastic stocks I’ve encountered in the past, this Manticore Arms unit is a significant step up in durability and long-term reliability, easily justifying its position as a premium upgrade.

Breaking Down the Features of Manticore Arms Scorpion EVO Slider Stock

Specifications

The Manticore Arms Scorpion EVO Slider Stock is a precisely engineered accessory designed for the CZ Scorpion EVO 3 platform. Constructed primarily from steel in its core components, with the mounting block featuring 6061 aluminum construction, it offers a robust feel. The finish is a Type III milspec hardcoat black anodizing, ensuring excellent durability and resistance to abrasion. When fully collapsed, it adds a mere 3/4″ of length and no additional width to the firearm, maintaining a remarkably slim profile. The stock offers a fully telescoping action, friction-locking at the closed position for a compact carry and “quick-pull” deployment to a locked open position. The maximum length of pull extends to 12.5 inches, providing ample adjustability for different shooters. Critically, the design ensures no interference with the ejection port in any position, including fully collapsed. For sling attachment, the mounting block features a QD point on the left side, and the buttplate includes a QD point on the top along with a sling loop on the underside. The buttplate itself is grooved for a secure grip against the shoulder and has provisions for mounting an optional rubber buttpad. The overall weight of the stock is 12.0 ounces, and its extended length is 9.125 inches.

These specifications translate directly into tangible benefits for the user. The choice of steel and 6061 aluminum speaks to the stock’s intended durability, capable of withstanding the rigors of regular use. The minimal addition to the firearm’s dimensions when collapsed makes it exceptionally well-suited for concealed carry or maneuvering in tight spaces, a significant advantage over bulkier stock designs. The assured clearance of the ejection port in all configurations is a crucial design element that eliminates a common operational frustration. Furthermore, the inclusion of multiple QD sling points and a sling loop provides excellent versatility for attaching various sling systems, catering to different carrying preferences and tactical needs. The grooved buttplate offers a good friction surface, and the option to add a rubber buttpad further enhances comfort for extended shooting sessions.

Performance & Functionality

In terms of its primary function, the Manticore Arms Scorpion EVO Slider Stock performs exceptionally well, largely delivering on its promises. The telescoping mechanism is smooth once adequately lubricated, offering a satisfying thunk as it locks into its open position. The ability to fire with the stock in any position, including fully collapsed, is a remarkable functional advantage, providing a level of adaptability rarely seen. This feature alone sets it apart from many alternatives that require deployment before firing. The friction lock at the closed position holds firm, preventing unwanted extension during movement.

However, there are nuances to its performance. As noted by some users and confirmed in my own experience, the “quick-pull” deployment can sometimes be a bit too quick or, conversely, slightly stiff, especially when new or in extremely cold conditions. It requires a deliberate, firm pull to achieve instant deployment. Conversely, retracting the stock can occasionally feel like it needs a bit more force than anticipated, sometimes requiring a more vigorous push. While gun grease helps, this slight resistance is a trade-off for the secure, positive lock-up. The ejection port clearance is, as advertised, excellent, and I experienced zero issues with spent casings being impeded.

Design & Ergonomics

The design of this slider stock is undeniably its strongest suit, heavily drawing inspiration from the iconic MP5A3. Manticore Arms has successfully translated that aesthetic and functional elegance to the CZ Scorpion platform. The steel construction lends a substantial, high-quality feel, while the Type III milspec hardcoat black anodizing provides a durable, non-reflective finish that complements the firearm. The slim profile when collapsed is a masterclass in ergonomic design, minimizing bulk and snag points.

Ergonomically, the stock is comfortable to shoulder, with the grooved buttplate providing adequate grip. The length of pull is adjustable, catering to a range of shooter sizes, and the mechanism for adjustment, while not explicitly detailed, relies on the inherent friction lock of the telescoping tubes. The integrated QD points are well-placed and allow for flexible sling configurations, a practical detail that often gets overlooked in aftermarket accessories. My only minor ergonomic quibble, shared by others, is the absence of a factory-installed rubber buttpad, which would further enhance shoulder comfort during prolonged firing sessions. While available separately, its necessity for some users might be a point of contention given the stock’s premium price.

Durability & Maintenance

The Manticore Arms Scorpion EVO Slider Stock is built like a tank. The steel components and 6061 aluminum mount suggest a lifespan measured in years, if not decades, of regular use. After extensive cycling and handling, there are no visible signs of stress, bending, or premature wear on the telescoping tubes or locking mechanisms. The hardcoat anodizing is exceptionally resistant to scratches and abrasions; I’ve had it brush against hard surfaces without leaving a mark.

Maintenance is straightforward, revolving around keeping the telescoping rails clean and lightly lubricated. A small amount of CLP or gun grease applied sparingly to the sliding surfaces is sufficient to maintain smooth operation. The integrated components mean there are no small parts to lose during cleaning, a significant plus. One potential area to monitor over the very long term might be the detents or locking points within the telescoping tubes, but given the quality of materials, this is more of a theoretical concern than an observed one. The overall impression is one of supreme durability, designed for hard use.

Accessories and Customization Options

The Manticore Arms Scorpion EVO Slider Stock comes with its core functionality built-in, focusing on the stock itself rather than a plethora of additional accessories. Its primary “accessory” is arguably the optional rubber buttpad that can be purchased separately. While not included, this is a valuable addition for those prioritizing comfort during extended shooting sessions, effectively mitigating felt recoil against the shoulder.

Beyond the buttpad, the stock’s design is inherently customizable through its integrated sling mounting points. The QD point on the mounting block and the QD point on the top of the buttplate, along with the sling loop on the underside, offer significant flexibility. This allows users to configure their sling setup precisely to their needs, whether for tactical carry, range use, or simple transport. The stock itself is a single unit for the CZ Scorpion EVO, so mechanical customization options are limited to its telescoping function.

Pros and Cons of Manticore Arms Scorpion EVO Slider Stock

Who Should Buy Manticore Arms Scorpion EVO Slider Stock?

The Manticore Arms Scorpion EVO Slider Stock is an excellent choice for CZ Scorpion EVO 3 owners who prioritize aesthetics and classic firearms design without sacrificing functionality. It’s ideal for those who want the iconic look of an MP5A3 telescoping stock and appreciate the robust, all-steel construction that promises longevity.
