Compact URG-I 11.5" SOPMOD Block 3 Configuration
This Tokyo Marui URG-I features a compact 750 mm to 825 mm overall length, making it easy to shoulder and fast to manoeuvre in tight environments. The 11.5-inch style barrel gives the rifle a practical balance between CQB agility and outdoor usability, while the STR-type stock provides a stable and comfortable shooting platform.
The result is a versatile gas blowback M4 airsoft rifle that performs well in close-quarters fields, mixed terrain and milsim loadouts where mobility, realism and precision all matter.
Strong Gas Blowback with 19 mm Piston
The rifle is equipped with Tokyo Marui’s advanced blowback engine using a large 19 mm piston. The bolt cycles in sync with each shot, delivering a sharp and immersive recoil impulse that gives the URG-I a realistic shooting feel.
For players who want a more authentic experience than a standard electric rifle, this GBBR airsoft rifle provides realistic sound, recoil, magazine changes and bolt operation.
Z-System Durability
Tokyo Marui’s Z-System improves long-term reliability by reducing stress on key internal components. The system helps prevent wear and damage to the bolt catch, while the piston absorber and friction-reducing bolt roller reduce strain during bolt movement.
This makes the URG-I 11.5" SOPMOD Block 3 a dependable choice for regular skirmishing, repeated training drills and demanding airsoft games where consistent operation is essential.
Realistic Controls and STR-Type Stock
The rifle accurately reproduces realistic M4-style operation. The charging handle is used to load the first round, the bolt catch engages after the bolt opens, and the rifle behaves like a true gas blowback platform during reloads and handling.
The STR-type retractable stock offers six length positions, allowing players to adapt the rifle to different body sizes, plate carriers and shooting stances. This improves comfort and control during both fast CQB movement and longer field games.
10.5-Inch MK16 M-LOK Handguard
The handguard reproduces the 10.5-inch Super Modular Rail MK16 M-LOK DDC style system. Its slim profile improves grip comfort, reduces bulk and gives the rifle a modern tactical appearance.
Three M-LOK rail sections are included in different sizes: 3-slot, 5-slot and 7-slot. These can be attached using the supplied hex wrench, allowing you to mount grips, tactical lights, PEQ boxes or other compatible 20 mm Picatinny accessories exactly where you need them.
Authentic URG-I Details
Tokyo Marui has recreated key URG-I details with precision, including the DD-type URG-I gas block, 11.5-inch style barrel and ambidextrous charging handle. These details give the rifle an authentic modern special operations look, making it ideal for collectors and players building a realistic Green Beret-inspired loadout.
Foldable Adjustable Sights
The front and rear sights are both foldable and adjustable for elevation and windage. They can be used as primary sights or as backup sights when paired with a red dot, holographic sight or magnified optic.
Because the sights are rail-mounted, they can also be repositioned or removed entirely depending on your preferred setup.
14 mm CCW Muzzle Compatibility
The standard muzzle flash hider can be removed to reveal a 14 mm counter-clockwise thread, allowing the installation of compatible silencers, tracer units or other muzzle accessories. This makes the URG-I easy to configure for CQB arenas, low-light games or tactical milsim builds.
35-Round Aluminum Die-Cast Magazine
The included 35-round aluminum die-cast magazine adds to the realistic feel of the rifle by replicating the weight and handling of a loaded real-style magazine. Its real-capacity format is ideal for milsim players who prefer authentic reload discipline and a more immersive game experience.
