HFC Stealth Assassin SOCOM MK23 Gas Airsoft Pistol with Silencer in Black
If you’re after surgical precision with a serious dose of stealth, the HFC Stealth Assassin SOCOM MK23 Gas Pistol delivers exactly that. This isn’t your average sidearm—it’s a full-size, non-blowback gas pistol modelled after the iconic MK23 SOCOM, famously fielded by special forces and tactical units. What sets this airsoft pistol apart is its sheer practicality in the field: ultra-quiet, gas-efficient, and packing enough punch to hold its own even against full-size rifles in CQB environments.
The 1:1 scale frame is matched with a 7.5” screw-on suppressor, which doesn’t just look intimidating—it actually houses an extended inner barrel. When attached, it boosts your FPS from around 300 to an impressive 320 with 0.20g BBs, giving you real performance gains along with that signature stealth aesthetic. Perfect for sneaky flanks and ambush tactics, the MK23 keeps you on target without ever giving away your position.
This pistol is a solid blend of lightweight ABS polymer for the body and durable metal internals where it matters most—trigger, hammer, barrel, safety levers, and the 28-round gas magazine. It’s a practical combo that ensures realism without unnecessary bulk. It weighs in at about 1kg, giving it a satisfying, balanced feel in the hand without being too cumbersome for a sidearm holster.
The real star feature here is the non-blowback gas system. Not only does this keep the MK23 whisper-quiet, but it also massively improves gas efficiency—letting you squeeze off more rounds on a single fill than most blowback pistols could dream of. That makes it a killer choice for longer games and milsim events where ammo and gas count.
Adjustments are easy too. The silencer screws on securely and acts as both a visual deterrent and a genuine performance booster. You can also manually cock the hammer or rack the slide for a bit of added realism—though the pistol will happily operate without doing so.
Whether you’re a collector, a fan of the “Hitman” or “Rainbow Six” series, or just someone who appreciates a dead-silent backup for skirmishes, the MK23 is an excellent pick. And it comes ready to go, complete with magazine, BBs, and user manual all neatly boxed. Stealth doesn’t get much smoother than this.
