Lancer Tactical Viking Proline Series M4

No, the Lancer Tactical Viking Proline Series M4 does not include a battery or charger. You will need to purchase a 7.4v small stick LiPo battery with a small Tamiya connector separately.

It is quite straightforward. The rifle features a quick-change spring system, which allows you to access and swap the spring without needing to disassemble the entire gearbox.

The rifle uses a free-float M-LOK rail system. This is a modern, modular mounting interface that allows you to attach M-LOK compatible grips, lights, lasers, and other tactical accessories directly to the handguard.

With a muzzle velocity of 380 FPS, this rifle is primarily designed for outdoor fields. You should check your local indoor arena's specific FPS limits, as many CQB sites require lower velocities and may consider this rifle too powerful for close-quarters engagement.

This rifle uses standard Tokyo Marui-style M4 AEG magazines. It comes with a 140-round mid-capacity magazine, but most aftermarket M4 AEG magazines should fit and feed reliably.

The integrated electric trigger unit with a fire cutoff system ensures a consistent cycle and prevents the gearbox from locking up during rapid semi-automatic fire. It provides a snappier trigger response compared to traditional mechanical trigger contacts.
