The video introduces the Century Arms AES-10B2, a semi-automatic RPK-style rifle that resembles a squad automatic weapon within the AK family. It is described as a Slavic counterpart to a light machine gun concept, built around the familiar AK platform but scaled up for heavier use. The rifle features a 21.5-inch barrel and wood furniture, retaining the traditional AK look and feel while offering a longer overall profile than a standard 16-inch AK. The presenters bring in an AK-focused subject matter expert to explain the specific design elements that distinguish this Romanian RPK-style rifle from a typical AKM-pattern carbine.
The AES-10B2 is identified as a Romanian version of an RPK-style rifle, manufactured at the Cugir factory in Romania. It is based on a variant of the 1963 Romanian military rifle derived from the AKM, which the Romanians referred to as the "pistolet mitralieră" pattern. The discussion notes that as Soviet small arms evolved, new designs were not always quickly shared with partner nations. The RPK concept provided a way to field a squad automatic weapon or even a designated marksman-style rifle when other platforms, such as the PSL, were not available. The AES-10B2 is essentially an enlarged AK designed to better handle sustained fire while remaining mechanically similar to the standard AK system.
Attention shifts to the structural differences that support heavier use. The AES-10B2 uses a 1.5 mm stamped receiver instead of the typical 1 mm receiver found on many AKM-pattern rifles, adding rigidity. It also incorporates a reinforced front trunnion with more interface between the trunnion and receiver for additional strength during extended firing. The rifle features the distinctive RPK-style clubfoot stock, which aids stability when shooting from the prone position and aligns with its role as a support weapon. The rear sight is highlighted as windage-adjustable, unlike standard AK rear sights, allowing the shooter to dial in windage rather than relying solely on hold-offs. Elevation remains adjustable at the front sight, with fine windage corrections at the front typically handled at the armorer level.
The integrated bipod is presented as a defining feature of the RPK-style configuration. It is attached near the front of the barrel and folds up to lock around a small stud, with a clip that retains the legs together when stowed. Each bipod leg is independently height-adjustable, and the feet include skid pads to help stabilize the rifle on various surfaces. These features support the rifle’s intended role of providing low, stable firing positions for either longer-range, more precise fire than a standard AK or for sustained support fire. The longer 21.5-inch barrel is noted as contributing to this extended reach and support capability compared to a typical 16-inch AK-pattern rifle.
The rifle retains the traditional AK operating system, including a long-stroke gas piston directly attached to the carrier and a rotating bolt, with components lengthened to match the extended RPK configuration. Internally, it functions like an AK despite its larger size and longer gas system. The presenters demonstrate the trigger, confirming the rifle is clear before handling. The trigger exhibits some initial take-up and travel with a bit of grit, but the break is described as clean and crisp, with a reasonably distinct reset. It is noted that while there are smoother stock triggers on other platforms, AK triggers, including this one, often have a satisfying break. Light polishing of contact surfaces, without altering engagement geometry, is mentioned as a way to reduce grittiness and improve overall feel as the trigger breaks in with use.
On the left side of the receiver, the AES-10B2 includes a standard AK-style side optics rail. This allows mounting of a side rail bracket that overhangs the dust cover, providing a platform for magnified optics or other sighting systems while preserving the rifle’s basic configuration. The rifle is chambered in 7.62x39 and uses standard-capacity AK magazines. It is mentioned that the rifle ships with a conventional magazine and also with an additional round, drum-shaped magazine, implied to be a 75-round drum, though not explicitly named. The presenters summarize the AES-10B2 as essentially a larger, reinforced AK-47 pattern rifle that offers extended range and support capability while maintaining the familiar AK ergonomics and manual of arms. Viewers with experience on Century Arms RPK-style rifles are invited to share their impressions in reviews and comments.
