Compatibility & Upgrades

The SA-C04 CORE Gen.2 sits on a V2 gearbox platform – one of the most modded gearboxes in airsoft. Expect hassle-free compatibility with standard replacement parts: piston heads, tappet plates, springs (adjust FPS), motors (increase rate of fire), and electronic triggers (for faster response). The 20mm rail ecosystem is mature; virtually any optic, laser, or accessory rail will fit. Magazine compatibility is standard AEG – hundreds of third-party options available.

UK Legal & Site Notes

At 330 FPS, the SA-C04 CORE Gen.2 complies with the UK airsoft legal framework (two-tone finish or UKARA exemption required; this model is full black – ensure you hold UKARA or arrange retailer two-tone service). Confirm your local site’s FPS limits before play; most venues accept 330 FPS in the assault rifle category. The programmable trigger is legal under UK rules.
