WE-Tech SMG-8 Airsoft GBB Sub Machine Gun

WE-Tech SMG-8 Airsoft GBB Submachine Gun — Compact Powerhouse (Green Gas/Propane)

Compact, hard-hitting, and loadout-ready — the WE-Tech SMG-8 is a gas blowback submachine gun designed for players who want realistic recoil, modular utility, and superb handling in a small package. Built with a high-strength polymer receiver and metal blowback components, the SMG-8 is equally at home as a primary weapon for CQB or as a fast, maneuverable secondary for aggressive field tactics.

Realistic, hard-kicking performance
The SMG-8 uses WE-Tech’s open-bolt blowback architecture with a metal barrel and internal blowback assembly to deliver a convincing, hard-kick recoil impulse most gas blowback fans crave. Powered by Green Gas, Red Gas, or propane, the SMG-8 produces a muzzle velocity of 370–400 FPS with 0.20 g BBs — a reliable envelope for indoor CQB and outdoor skirmishes when tuned to field limits. Its heavyweight full-metal magazine also adds balance and that authentic heft during handling and reloads.

Compact, tactical-ready platform
Measuring 419 mm retracted / 645 mm extended, the SMG-8 is highly maneuverable in tight spaces yet offers the stability of an extended stock when you need it. The extendable stock deploys quickly with a button for instant transition between compact carry and a stable firing position. An integrated 20 mm accessory rail system lets you mount lights, lasers, foregrips, and optics to customize the gun for night games, breaching runs, or specialist roles.

Durable construction and ergonomic handling
A high-strength polymer receiver keeps overall weight manageable (approx. 1,660 g) while resisting impact and harsh field conditions. The textured ergonomic pistol grip and polymer butt plate provide secure, comfortable purchase during long matches. Fixed front and adjustable rear sights give you reliable backup aiming should you choose not to mount an optic.

Precision and range — REAPS style hopup
The SMG-8 features a REAPS-style hopup designed for improved range and accuracy. Note: this hopup is not compatible with standard WE-Tech inner barrels, so keep that in mind when upgrading. The factory inner barrel (≈184 mm) and hopup pairing deliver consistent groups and dependable trajectory when combined with quality BBs and proper gas choice.

Magazine & capacity
The included heavyweight full-metal magazine holds 44 rounds, providing quick, responsive reloads and realistic magazine weight. Its durable construction and feed design ensure dependable cycling and minimal issues during rapid strings of fire.

Versatile gas compatibility
Use Green Gas, Red Gas, or Propane depending on your local field rules and temperature conditions. The SMG-8’s open-bolt blowback design and metal internals are engineered to withstand repeated high-pressure operation, but always follow safe charging practices and field guidelines.

Who the SMG-8 is for

• CQB players who need a compact, agile primary with serious recoil and control.

• Skirmishers who want a realistic sidearm/backup that still functions as a fight-capable weapon.

• Tech-minded players who appreciate a robust metal blowback assembly and upgrade potential.

• Teams running fast, close-quarters tactics that require speedy transitions and versatile accessory fitment.
