Pistons, Cylinders & Heads

Pistons, cylinders, and cylinder heads are the heart of your AEG’s compression system, directly influencing power, consistency, and long‑term reliability. Whether you’re upgrading for higher FPS, improving air seal, or replacing worn components, these parts play a crucial role in how efficiently your gearbox performs. A well‑matched compression set can transform your rifle’s shot‑to‑shot consistency and overall feel.
Our range includes reinforced pistons, precision‑machined cylinders, ported and non‑ported designs, durable piston heads, and high‑quality cylinder heads built for optimal air seal and reduced vibration. Each component is selected for strength, compatibility, and performance across popular gearbox versions. From lightweight polymer pistons for high‑speed builds to full‑metal options for high‑power setups, you’ll find the right parts to match your tuning goals.
If you’re rebuilding a gearbox, chasing tighter FPS consistency, or pushing your AEG to the next level, upgrading your pistons, cylinders, and heads is one of the most effective ways to boost performance. Explore the collection and build a compression system that delivers every time you pull the trigger.
