M.O.S. Arcturus Vanguard 5.1 Hi-Capa GBB Airsoft Pistol

Built for fast handling and dependable performance, the M.O.S. Arcturus Vanguard 5.1 combines gas-efficient operation, durable construction, and upgrade-friendly Hi-Capa compatibility in a compact competition-style airsoft pistol.

Product Overview

The Arcturus Vanguard 5.1 Hi-Capa is a green gas blowback airsoft pistol engineered for CQB, competitive play, and recreational skirmishing. Its compact 5.1-inch platform offers responsive handling, while the adjustable hop-up and precision-designed internal components help deliver consistent accuracy and an estimated velocity of 300–320 FPS with 0.20g BBs.

Ten high-grade MIM steel components provide durability in critical operating areas. The reinforced nylon-fiber grip features molded stippling for comfortable, controlled handling, while the ambidextrous magazine release supports both right- and left-handed players. Its 31-round gas magazine uses impact-resistant SEFP feed lips, follower, and base plate for greater reliability during demanding gameplay.

Common Product Questions

Find quick answers about our airsoft products, shipping and policies.

Can LA Airsoft install this part for me?

Yes. We can build and upgrade Hi-Capas, AAP platforms, and rifles. Choose your base gun and parts, then add the appropriate tech service.

The current custom-build service states that builds are normally completed in approximately 3 to 5 days, with the team reviewing the selected parts for compatibility.

Do I need tools or gunsmithing?

That depends on the upgrade. Simple external parts may be straightforward, but internal upgrades can require disassembly, reassembly, adjustment and testing.

If you are not comfortable working inside your airsoft gun, our team offers professional tech and custom-build services.

How quickly will my order ship?

Orders without preorder items are typically packed the same day when placed before 4:30 p.m. Central Time. Please note that occasional delays can occur during especially busy periods or when staffing is limited.

How should I maintain this product?

Regular maintenance helps preserve performance and reliability. Keep the product clean, follow the manufacturer’s lubrication instructions, and properly manage batteries, gas systems, and internal components. More advanced repairs or internal servicing should be handled by an experienced airsoft technician.

Will this part fit my platform?

Compatibility is product-specific. Check the brand, model, size, and platform named in the product description, such as Tokyo Marui Hi-Capa 4.3 or 5.1, AAP-01, Umarex/VFC Glock, or a particular AEG gearbox type.

Similar-looking parts are not always interchangeable, so contact our team with your exact model if you are unsure.

Will this part increase my FPS?

Not every upgrade increases FPS. Some parts are designed primarily for reliability, cycling speed, weight reduction, or gas efficiency. When a product has a tested FPS claim, it should be stated in the listing.
