The video features a Pioneer Arms Hellpup AK-47 pistol chambered in 7.62x39, shown with a 100-round drum and a FosTech Echo AK trigger installed. The host explains that semi-automatic fire is standard, but the Echo mode effectively doubles the shots by firing on both the trigger pull and release. He notes that, as defined by the ATF, this is not a machine gun because each pull and each release are considered separate functions, with only one round fired per function. Classic Firearms partnered with Pioneer Arms and FosTech to offer Hellpup pistols that come from the factory with the Echo AK trigger already installed, giving the compact AK pistol an upgraded fire-control system and distinctive safety selector markings.
The Hellpup is described as a compact, fun AK pistol that many shooters enjoy. The FosTech Echo AK trigger installed in it is compared to other FosTech products, such as the AR Gen 2 and Echo Sport triggers. The feel of the AK Echo trigger reminds the host somewhat of the Echo Sport, though the AK platform naturally feels different from an AR. Semi-auto mode functions normally, while Echo mode enables quick pairs of shots with each pull and release. The safety selector is highlighted for its clean appearance and clear markings for semi and Echo modes, adding a more refined look to the AK platform without significantly changing the pistol’s overall appearance.
The Hellpup is shown running reliably with various magazines, including a last-round bolt-hold-open magazine used as a range mag and a Pioneer polymer Gen 3 “waffle” magazine with a textured exterior and round-count indicator. The waffle mag is noted as slightly thick, which helps it lock tightly in the magazine well. A 100-round drum magazine is also used, complementing the Echo trigger’s fast follow-up capability. During extended firing, the short 7.62x39 system heats up quickly, and the polymer handguards transmit noticeable heat. The host recommends wearing thick gloves for mag dumps or high-volume shooting, explaining that the pistol earns its “Hellpup” name by getting very hot under sustained fire.
The Hellpup is characterized as a small, hard-hitting 7.62x39 AK pistol that produces a pronounced fireball, especially at night. It is not presented as a precision platform but as a compact firearm that is easy to run at closer distances, even with the increased shot cadence from the Echo trigger. Despite lacking a brace in the video, the pistol remains controllable at typical short ranges. The host notes that adding a pistol brace and appropriate adapter would make the platform easier to stabilize during continuous strings of fire or repeated mag dumps. The overall impression is of a compact AK pistol that is simple, robust, and eager to run large volumes of ammunition.
The video covers how to install a pistol brace on the Hellpup using a FosTech brace adapter. Installation involves loosening the grip screw on the FosTech Saber-style grip, sliding the adapter into place under the grip, and then tightening the grip back down so the adapter sits recessed at the rear of the receiver. The host emphasizes that this is a pistol brace, not a stock, and that adding a brace to a firearm originally manufactured as a pistol does not convert it into a rifle. Viewers are urged to research and comply with all local, state, and federal laws, and to do their homework before making any modifications, particularly regarding NFA-related regulations.
The FosTech Echo AK trigger is discussed in more detail, with the host referencing his broader experience with FosTech rifles and triggers and his positive view of the brand. The Hellpup’s safety selector allows the bolt to be charged while on safe, unlike some designs where the safety blocks bolt movement. The selector positions are explained: one position for semi-automatic fire and a middle position for Echo (binary-style) operation, where the firearm fires on both pull and release. The selector markings are clearly visible on the receiver, making it easy to identify the chosen mode. The trigger is described as smooth and reliable, with the Hellpup running “like butter” during testing, including relatively hard use to confirm function.
The Pioneer Arms Hellpup is described as a compact AK pistol from Radom, Poland, and part of a broader line of Pioneer products previously covered by Classic Firearms, including the Pioneer Sporter rifle. The host mentions prior conversations with Pioneer at SHOT Show and expresses interest in visiting their facility in Poland to see the rifle-building process. Pioneer rifles and pistols are portrayed as smooth-running, durable platforms that many customers report as reliable, with Pioneer providing support when issues arise. The Hellpup with the factory-installed FosTech Echo AK trigger is presented as a particularly enjoyable configuration, and standalone Echo AK triggers are also available for those who already own an AK and want to add the same trigger system.
