Description.

The SRC M933 M4 Carbine AEG – Black isn’t here to dazzle with gimmicks or gaudy externals. It’s built to do one thing well: deliver solid airsoft performance, consistently. Whether you're gearing up for your first CQB match or just need a no-fuss, skirmish-ready M4 platform that won’t flinch under pressure, this rifle has you covered.

Crafted with a lightweight polymer body, it weighs in at just 2.96 kg, which makes it surprisingly manageable for longer ops, especially if you're running light or sprinting between cover. The adjustable stock takes it from a compact 763 mm to a more rifle-like 845 mm — handy when switching from room clearing to covering fire roles. It’s versatile, and it feels right in your hands.

Internally, the real meat of the rifle is the Version II full-metal gearbox. It’s built to the tried-and-tested Tokyo Marui spec, so future upgrades or replacements won’t be a pain. Inside, you’ll find balanced steel gears riding on 6 mm self-lubricating bushings. That means smoother cycling and less maintenance in the long run. Combine that with an ultra high-torque motor and you’re putting out roughly 800 rounds per minute. Not too shabby for an airsoft rifle in this price bracket.

The 370 mm inner barrel offers a solid range and accuracy profile, especially once you tweak the adjustable metal hop-up to your preferred weight of BBs. A well-dialed hop-up can make the difference between just tagging someone and consistently landing those longer shots, and this M933 gives you the tools to do it. It outputs around 0.96 joules, which keeps it site-legal across most UK skirmish fields, but still hits with a satisfying punch.

The included 300-round high-cap mag means fewer trips to cover just to reload. Pop it in and you’re good to rain plastic downrange for longer engagements. Fire selector options give you the expected safe, semi-auto, and full-auto settings, so you can go loud or play it sneaky depending on your mission. And while it doesn’t ship with a battery, it's compatible with 8.4v 1200 mAh mini-type packs — easy to source and reliable to run.

Bottom line: the SRC M933 M4 Carbine AEG isn’t trying to reinvent the wheel. Instead, it refines the essentials into a package that’s straightforward, reliable, and ready for action. Great for newer airsofters finding their loadout groove or as a dependable backup rifle for veterans who know the value of simplicity.
