SRC M933 M4 Airsoft Rifle AEG – Tactical Black

The SRC M933 M4 Carbine AEG in Tactical Black is a no-nonsense workhorse of an electric rifle that thrives on reliability and battlefield versatility. Whether you're navigating tight corners in CQB environments or laying down suppressive fire in outdoor skirmishes, this airsoft rifle offers a rock-solid platform for players who prefer performance over flash.

Weighing in at just 2.96 kg, the polymer construction of this M4 keeps things light without sacrificing durability. It feels nimble in-hand, and thanks to the adjustable six-position stock, it transitions easily between close-quarters and field roles. You can collapse it down to 763 mm for those tight entries or extend it out to 845 mm for more controlled, stable shots across distance.

Under the hood, this rifle runs a Version II metal gearbox – one of the most widely supported platforms in airsoft. It's based on Tokyo Marui specs, so future upgrades or repairs are straightforward. Internally, you’ll find balanced steel gears seated on 6 mm self-lubricating bushings, keeping everything cycling smoothly while reducing the need for constant maintenance. It’s paired with a high-torque motor that churns out roughly 800 BBs per minute – more than enough to hold your own in sustained firefights.

Accuracy isn't an afterthought here either. The 370 mm inner barrel gives you a decent reach, and with the precision-adjustable metal hop-up system, you can fine-tune your BB trajectory to suit different weights or engagement ranges. Power-wise, it clocks in at 0.96 joules, which keeps it within UK site limits while still giving you a satisfying crack with each shot.

With a 300-round high-capacity magazine included, you're covered for longer engagements without scrambling for a reload. Fire mode options include safe, semi-auto, and full-auto, giving you tactical flexibility to match the scenario. Whether you're laying down cover or picking off targets in semi, the trigger response remains crisp and consistent.

Externally, the rifle keeps things sleek and practical. The sturdy metal outer barrel adds realism and weight balance, while a quick-detach rear sling plate lets you customise your sling setup for comfort or mission-specific carry styles. The mock flash hider comes pre-installed, but you also get a slick black metal alternative in the box if you prefer a more subdued look.

It’s worth noting that while it doesn’t include a battery out of the box, it’s compatible with standard 8.4v 1200 mAh mini-type packs – easy to source and fit into the compact handguard space. Whether you're a beginner after your first reliable skirmish rifle or a seasoned player wanting a trustworthy backup that won’t let you down, the SRC M933 M4 delivers exactly what you need, minus the fluff.

This is the kind of airsoft gun that doesn’t scream for attention but earns respect where it counts – on the field.
