• Rotary hop-up – precise range tuning for consistent shot placement
• Railed side mount + Russian AK side rail – scope and optics-ready without rail modifications

Real-World Use Cases

This AK excels in milsim scenarios where Eastern-Bloc loadouts are central to gameplay. Its 340 fps output sits comfortably within most UK site velocity limits (typically 350 fps with 0.20g), giving you instant compliance and safe engagement at standard engagement distances. The side-folding stock and compact 700 mm length make it nimble in close-quarters team rooms and multi-floor buildings, whilst the full-metal construction ensures it can handle rough handling on overnight operations. Programmable fire modes let you dial in semi-only for precision engagements or full auto for suppressive fire, adapting to each mission phase.

Compatibility & Upgrades

The SA-PJ04 uses standard AK-pattern 130-round medium-capacity magazines, widely available in the UK airsoft market. The V3 gearbox accepts common upgrade springs, shimming kits, and piston assemblies, letting you fine-tune velocity or rate of fire down the line. The Russian side rail integrates Picatinny optics and red-dots without drilling, and the rotary hop-up dial is accessible for quick field adjustments. The 7.4V Deans battery is industry-standard; upgrading to an 11.1V LiPo will increase rate of fire and snappier trigger response if your gearbox and motor can tolerate the extra strain.

UK Legal & Site Notes

At 340 fps, this AEG complies with UK airsoft site velocity limits and requires no velocity reduction out of the box. It is legal to own and use at registered sites and events nationwide. Two mid-cap magazines and a speed loader are included to get you playing immediately. Always check individual site rules for magazine capacity limits and fire-mode restrictions—some sites enforce semi-only rules, and the programmable function lets you lock into that mode if needed.
