Lancer Tactical Gen 2 Polymer Rotary Hop-Up Parts

If your Lancer Tactical Gen 2 is throwing inconsistent shots, the first place to look isn't a new spring or a different motor. It's the hop-up. The factory polymer rotary hop-up parts wear over time — the bucking flattens, the nub rounds off, and your adjustment stops doing what it's supposed to.

This set replaces the worn parts with a fresh polymer rotary hop-up chamber, bucking, and nub. The rotary design adjusts through a dial rather than a single lever point, which applies more even pressure to the BB. That's the single most impactful change for shot-to-shot consistency on an entry-level AEG, and it matters more than any spring upgrade if your hop is shot.

Installation means splitting the receiver, which is standard gearbox work. The parts drop in, you set the hop with the provided tool, and everything stays polymer. If the bucking on your current unit is bald or the nub is rounded over, this replacement makes a fresh spring actually do something useful.

Gen 2 only. These won't fit V3 platforms, Tokyo Marui gearboxes, or other brands' rotary systems. Verify your platform before you crack the receiver open.
