WE Apache MP5 SD1 Gas Blowback Airsoft Submachine Gun in Black

Stealth meets firepower in the WE Apache MP5 SD1 Gas Blowback Airsoft Submachine Gun—a serious CQB performer that merges iconic MP5 styling with the raw realism of a gas blowback platform. Built for players who favour subtlety and precision, the SD1 is the quiet operator’s dream: suppressed, sleek, and snappy in-hand. If you’re into tactical immersion and responsive handling, this isn’t just a replica—it’s a statement piece.

Visually, the Apache SD1 nails the classic silenced MP5 silhouette. That integrated 300mm suppressor isn’t just for looks—it houses an extended inner barrel that boosts range and tightens groupings, giving you that edge during stealth missions or close-quarters ambushes. At 790mm long and weighing in at around 3.1kg, it’s got presence without being unwieldy. The fixed stock provides a solid, recoil-absorbing anchor for controlled burst or full-auto fire.

On the inside, it’s all GBB goodness. The blowback system delivers proper bolt cycling and recoil kick with every shot, offering a level of immersion that electric rifles can’t quite match. It runs around 320 FPS on Green Gas, keeping it within most indoor site limits while still giving enough poke for outdoor engagements. The 45-round metal magazine holds plenty for aggressive pushes or controlled recon roles, and the built-in dry-fire mode is perfect for training between skirmishes.

The controls are a standout feature too. Fully ambidextrous with selectors and mag release on both sides, this rifle welcomes lefties without compromise. Fire modes include Safe, Semi, 3-Round Burst, and Full Auto, giving you options for every type of engagement—from methodical tap shooting to room-clearing bursts. The adjustable metal iron sights include four rear apertures, giving you options to match light conditions or personal preference.

Construction is rock solid. The steel upper receiver is built to take a beating, while the nylon polymer lower helps shave a bit of weight without compromising durability. The polymer handguard gives 180mm of support space and excellent heat resistance under extended firing, while the Picatinny top rail means optics are just a mount away—whether that’s a red dot or compact CQB scope.

The hop-up is adjustable for fine-tuning your shot trajectory, and once dialled in, the performance is surprisingly consistent for a gas blowback. Combined with the longer barrel and suppressor, you’ll find the SD1 can comfortably reach targets out to 40–50m with 0.25g BBs and a tuned hop. It’s got just enough reach for those longer shots without stepping into DMR territory.

In terms of feel, the SD1 hits the sweet spot—recoil is punchy, cycling is smooth, and reloads feel tactical and satisfying. It's a brilliant alternative for anyone bored of the usual gas pistol routine, looking to upgrade to something with a bit more bite and battlefield presence.

If you're after a quiet powerhouse that punches above its size class—and looks damn good doing it—the Apache SD1 should be at the top of your GBB wish list. This isn’t a toy. It’s a workhorse for serious players who want immersive realism and flexible tactical capability in one classic package.
