The video opens with relaxed banter between Ryan and Adam before shifting into a focused discussion on US Palm. They outline how US Palm started with soft gear like chest rigs and evolved into a major name in AK accessories, especially magazines and grips widely used by Century Arms and other manufacturers. The hosts reference collaborations such as the exclusive alien green US Palm AK magazines done with Classic Firearms, underscoring the brand’s established credibility in the AK world. From there, the conversation turns to US Palm’s deliberate decision to enter the AR market. Rather than copying existing rifles, the company brought in experienced engineers and told them to redesign the AR platform from a clean sheet, without legacy constraints. The stated goal was meaningful innovation in longevity, reliability, and performance, instead of releasing another basic, incremental AR into an already crowded, price-sensitive segment.
The hosts explain that US Palm intentionally avoided the crowded sub-$500–$600 budget AR-15 space. Instead, they launched a feature-rich platform to stand out from commodity rifles. This strategy produced the US Palm Storm series, centered on the Storm CAT4 patrol rifle and pistol configurations, with a Cat 5 competition model and a more affordable Cat 3 planned. The CAT4 is described as carrying 16 patents, which impresses even the AR-enthusiast host. These patents target improved longevity, performance, and reliability rather than cosmetic tweaks. Specific engineering details include a screw and stabilizing pin system that reinforces the upper receiver’s cam path, reducing wear over high round counts. The rifle is framed as a purpose-built, hard-use platform rather than a parts-bin build, with the design work focused on durability and real-world shooting benefits.
Attention turns to the Hurricane flash hider on the US Palm CAT4. The device has an aggressive, almost brutalist appearance, but the hosts emphasize that its design is driven by function: durability, recoil reduction, and flash mitigation. They note plans to show how it behaves on the range, especially on shorter barrels. The discussion then moves to the proprietary Monolock upper system. Instead of an expensive one-piece monolithic upper, US Palm created a system where the upper receiver locks into the rail and the rail mounts to the receiver rather than the barrel. This approach aims to deliver true free-float performance and monolithic-like rigidity without the high manufacturing cost. The result is a more stable optic platform and improved consistency under hard use, while keeping the rifle within a realistic price bracket for serious shooters.
The CAT4’s user-facing features are highlighted next. The rifle includes fully ambidextrous controls, catering to left-handed shooters and those who train offhand. A redesigned charging handle is intended to mitigate gas blowback, especially important when running suppressors. The safety is a 45° selector for faster, more ergonomic manipulation compared to traditional 90° levers. US Palm partnered with Hyperfire to equip the CAT4 with a two-stage trigger, giving a cleaner break and better control than standard mil-spec triggers. An enhanced bolt release further improves handling during reloads and malfunction clearances. All of these features are positioned as enthusiast-focused, meant for battle, duty, and competition use. Despite the premium components and patented design, the rifle’s price is discussed as coming in under $1,500, with initial offerings in black rifle and pistol formats and a forthcoming anodized storm green finish.
The video introduces US Palm’s EOS (Eye of the Storm) line of 3D-printed suppressors, expanding the brand beyond rifles. The lineup includes models for 5.56 and 7.62, a dedicated AK suppressor, a .30-cal option, and a titanium EOS 30 TI. The hosts stress that non-titanium cans use Inconel for hard-use durability, while the titanium model targets lighter weight. They discuss engineering tradeoffs between maximum sound suppression, flash reduction, carbon buildup, and long-term reliability, noting that US Palm prioritized a balance suitable for sustained firing rather than chasing the quietest possible meter numbers. All suppressors are manufactured and shipped from West Palm Beach, Florida, reinforcing the American-made branding. Returning to the CAT4, they mention hammer-forged barrels capable of sub-1 MOA accuracy, noticeable recoil mitigation from the monolithic-style design and Hurricane flash hider, the Hyperfire two-stage trigger partnership, and a DLC-coated bolt that enhances reliability and simplifies cleaning.
The hosts dive deeper into the CAT4’s internals and testing. They explain that the rifle uses a DLC (diamond-like coating) bolt, chosen for its slick surface, resistance to carbon buildup, and extended service life. This is paired with the monolithic-style lockup and mounting system designed to maintain a stable field of view and structural integrity under high round counts and harsh conditions. They outline US Palm’s testing protocol, which involved multiple rifles and escalating round counts. Across roughly 45,000 rounds, they report only about six or seven malfunctions, a notably low failure rate. One standout metric is 12,000 rounds without a bolt lock shear, where typical AR bolts often fail around 5,000–8,000 rounds. These results give the hosts confidence in the CAT4 as a true battle rifle. Ergonomic touches like an integrated trigger guard are mentioned, designed to prevent finger discomfort during extended shooting and slated for further evaluation in an upcoming training class.
Looking ahead, the hosts talk about an upcoming training course that will involve extensive offhand shooting, making the CAT4’s ambidextrous lower particularly relevant. They expect it to outperform traditional setups in transitions and non-dominant-side work while remaining comfortable on the firing hand. The scene then shifts to the range with the 16-inch CAT4. During live fire, they immediately comment on the rifle’s monolithic-style feel, noting how solid and cohesive the upper and rail assembly seem. The ambidextrous controls are used in real time, reinforcing their practical value. The Hyperfire trigger, described as an EDT-type, earns praise for its crisp performance and controllable two-stage pull. They observe an unusual recoil impulse that pushes more to the side rather than the typical up-and-right movement seen on many ARs, and mention some odd cheek feel from the stock or cheek weld. A consistent ejection pattern and well-tuned gas system are highlighted as signs of a well-balanced AR.
The focus shifts to the shorter-barreled CAT4 variant. On the range, the hosts note that despite being a 5.56 with a short barrel, its recoil is impressively well controlled. The unique conical, banana-peel-like flash hider draws attention for its unconventional look, but its performance exceeds expectations, keeping flash and movement in check. They explain that the short barrel produces a more violent gas return and noticeable shake, yet the rifle still exhibits minimal muzzle rise. The discussion distinguishes between perceived recoil, influenced by sound and blast, and actual felt recoil at the shoulder, which remains manageable. Gas management is praised, with no noticeable bleed-off into the support hand area. Ergonomically, they dislike the specific brace style on this configuration but commend the pistol grip, 45° safety selectors, and a large, robust charging handle. The segment also touches on future CAT-series possibilities, including a potential .308 “Cat 5,” and the engineering behind the 3D-printed conical muzzle device.
In the closing portion, the hosts outline plans for more aggressive testing of the CAT4 platform. They discuss running a burndown test and shooting the rifle fully suppressed, potentially with an FRT trigger, to push the system under extreme conditions. There is a strong desire to take the rifle into a full training course to evaluate reliability, ergonomics, and heat management over long days and high round counts. They return to the topic of value, expressing surprise that the rifle includes a DLC-coated bolt at an MSRP of about $1,399, a feature usually reserved for more expensive builds or aftermarket upgrades. This, combined with the patented design elements, ambidextrous controls, Hyperfire trigger, and monolithic-style upper, leads them to praise US Palm’s engineers for thoughtfully combining top-tier market features into a consumer-focused package. The video wraps with a brief sign-off and thanks to viewers, leaving a strong impression of the CAT4 as a serious, hard-use AR-15 option.
