Lancer Tactical ProLine Gen 2 M4 SD AEG (LT‑15B‑G2‑ME)
A compact, hard-hitting M4 built for players who want upgraded internals straight out of the box. The ProLine Gen 2 takes the standard Lancer M4 platform and adds a full‑metal upper/lower assembly, a CNC machined buffer tube and a polished 6.03mm tight bore barrel to sharpen accuracy and increase effective range without sacrificing CQB manoeuvrability. The mock suppressor and short handguard make it ideal for skirmishes where quick target acquisition matters.
Internally this rifle is where it shines: an 18:1 reinforced steel gear set, 8mm bushings and a 25k high‑torque motor give fast, consistent cycling, while low‑resistance copper wiring and an integrated MOSFET / Lancer Fast Trigger boost trigger response and protect contacts. The ProLine also includes a true quick‑change spring system accessible through the buffer tube so you can move from CQB to outdoor FPS ranges without opening the gearbox.
ergonomics and practicality were considered too — an improved crane stock with rubberized buttpad, enlarged trigger guard for gloved use, and a 20mm top rail for optics make this a field‑ready package. It ships with a 120‑round midcap, and the wiring and battery protection features extend battery life and reliability during long sessions.
Whether you want a solid starter platform for upgrades or a dependable “out of the box” performer, the LT‑15B‑G2‑ME ProLine is a great balance of durability, performance and value for skirmish players.
