Saigo Defence KENJI Zero Fighter Airsoft AEG Rifle Long Version in Black/Tan

Saigo Defence KENJI Zero Fighter Airsoft AEG Rifle Long Version in Black/Tan

If you're after a dependable workhorse of an airsoft rifle—one that’s modern, modular, and doesn’t overcomplicate things—the Saigo Defence KENJI Zero Fighter Long Version might just be what you're looking for. This isn’t some over-styled showpiece. It’s a tool. A lightweight, M-LOK-equipped AEG built around reliability and ease-of-use, all while packing an ETU and a metal-reinforced gearbox. And yes, it even comes with a LiPo battery and charger—ready to roll out of the box. Handy, right?

The body is made from reinforced polymer, and it’s not just to shave weight—it adds durability while keeping the balance right. Whether you're holding angles all day or running and gunning through mixed terrain, the KENJI Zero Fighter doesn’t swing around like a boat anchor. It feels tight, solid, and ready for hard use. The top rail runs full length from the receiver to the front, offering loads of space for optics, magnifiers, and backup sights. Add in the M-LOK slots at 3, 6, and 9 o’clock and you’ve got a clean rail setup that won’t weigh you down with unnecessary bulk.

The heart of this AEG is where things get serious. Inside, you've got metal wear components where they matter most—piston teeth, nozzle, and cylinder head. That’s not just for show. These parts take a beating, and with them being metal from the start, you’re not running into premature wear after your first few skirmishes. Combine that with the ETU (Electronic Trigger Unit) and you’ve got a crisp, responsive trigger feel with semi-auto that actually responds when you need it to. It also helps with contact longevity—so no more burnt trigger plates from old-school mechanical switches.

Performance out of the box lands in the 300–350 FPS range depending on your local retailer’s tuning and BB weight. That’s perfect for most outdoor UK sites. Pair it with some heavier BBs—say 0.28g or 0.30g—and this thing tightens up mid-range shots nicely. Thanks to the tight hop-up window and solid air seal, it stays consistent. Want to push further? Clean the barrel, fit a good bucking, and you'll be surprised how well it holds groupings past 40 metres.

The long version also comes with a 130-round mid-cap magazine. No rattle, no winding—just clean, quiet feeding and a great option for players who prefer a more tactical, low-profile reload style. The mag fits snug, feeds reliably, and keeps your loadout trim. The rifle also features a 14mm CCW threaded muzzle, so adding a tracer unit or suppressor is straightforward—no weird proprietary adaptors needed.

Handling feels sharp. The blade-style trigger is paired perfectly with the ETU, making semi-auto shots snappy and full-auto bursts controlled. Flip-up sights are included, fold flat when not in use, and co-witness well with most optics. The overall length on the Long version gives you a bit of extra barrel for outdoor accuracy without making it a pain to carry. It balances well, even with accessories fitted.

The included vertical grip and LiPo battery + charger bundle sweeten the deal. No need to faff around sourcing parts before your first game—you’re skirmish-ready from the moment it hits your doorstep. Just charge the battery, load the mag, and you're good to go. For newer players or those looking to upgrade from rental-grade gear, this is a solid, reliable next step.

Want to upgrade? You’ve got options. V2-style internals make hop-up swaps, barrel upgrades, or motor changes a breeze. The ETU keeps your trigger crisp, and with metal internals at stress points, you don’t need to dive in right away. It’s one of those platforms that performs well out of the box, but also grows with you as you tweak and refine your setup.
