The video opens at the Octas booth in Nuremberg with a close look at a Turkish-made rifle that strongly resembles the SIG MCX, informally dubbed the “Turkish MCX.” The presenter emphasizes how light and smooth the platform feels, noting that in full-auto configuration it reportedly runs very smoothly. Key to its appeal is a captured bolt system and MCX-like handling, aimed at delivering modern performance at a disruptive price point. While final pricing is not yet set, the goal is to come in under $1,000 in the U.S. market. The rifle uses a 1913 rear interface with a telescoping stock that can be swapped for other 1913-compatible options. For U.S. import, it will arrive as a pistol without a buttstock due to the short barrel. It accepts standard AR-15 grips and trigger groups, uses a traditional AR-style charging handle, and incorporates a captured buffer system. The example shown is a 300 Blackout model with a 10-inch barrel, while Century Arms is expected to bring in 7.5-inch pistol variants for American buyers.
The next section focuses on the rifle’s controls and military-oriented design. It features ambidextrous bolt release and bolt catch controls similar to the MCX, with a planned ambidextrous magazine release and fire selector on both sides to support left- and right-handed shooters. A removable trigger guard is included to accommodate gloved or mittened hands, aligning with military requirements. The manufacturer reportedly holds a Turkish military contract, and this platform is said to have passed a 15,000-round endurance test along with NATO-style environmental and drop testing. Externally, the rifle offers M-LOK slots along the handguard and a full-length Picatinny rail on top for optics and accessories. The handguard is tightly captured with minimal play, contributing to a solid feel. The anodized finish is smooth rather than sandy, avoiding overly aggressive texture while still looking duty-ready. The non-U.S. model shown here runs a 10-inch configuration and uses 5/8x24 muzzle threads, allowing users to choose their preferred muzzle devices or suppressors.
Attention then turns to the fire control and gas system strategy. The rifle is equipped with a single-stage defensive trigger that has noticeable weight and a moderately long reset, tuned more for reliability and duty use than for ultra-light competition shooting. The presenter explains that the U.S. import versions will receive an adjustable gas block, a key upgrade aimed at optimizing performance with both suppressed and unsuppressed 300 Blackout. This is particularly important for subsonic ammunition, where proper gas regulation can dramatically improve reliability and recoil characteristics. The goal is to deliver a shooting experience comparable to compact, suppressed platforms like a Rattler-style setup, with soft recoil and very quiet operation reminiscent of an MP5 running subsonic loads. Combined with the 5/8x24 threading and short barrel lengths, the design clearly targets users who want a compact, suppressor-ready pistol that can handle a wide range of 300 Blackout loads while maintaining control and comfort.
Later in the video, after a cut for YouTube guidelines, the presenter shows the internals of the gun. The bolt and carrier are described as clean and well-captured, with tidy internal machining that suggests good manufacturing tolerances. The charging handle is specific to this MCX-style operating system, and a standard AR-15 charging handle will not work due to the different design. The firearm is identified as the SEM Oct 300 in 300 Blackout, with mention of a 5.56 NATO version and a 12-inch model that uses a more traditional buffer system while still retaining the 1913 rear interface. For the U.S. market, Century Arms is expected to import pistol variants, including a 7.5-inch 300 Blackout and roughly 10-inch 5.56 configuration. Century will likely assign the final U.S. model name. The presenter acknowledges that Turkish firearms can have mixed reputations but concludes that this example feels well-made, with solid build quality and promising potential as an affordable, MCX-style option under $1,000.
