Lonex Extreme Toughness Piston (10-Teeth - Burgundy)

  • Model: GB-01-65
  • Shipping Weight: 0.032kgs
  • Manufactured by: Lonex


A lot of thought has been put into this piston by Lonex and it definitely shows.

This burgundy piston is made out of a proprietary blend of 20-30% fiberglass and polyamide (NOT polycarbonate or regular plastic, which means it won't shatter) for the most demanding setups. For short-stroke setups, this Lonex piston features 10 steel teeth so you can short-stroke and lighten to your heart's content. These teeth are heat-treated steel and CNC machined, and Lonex has left a one-piece reinforcement bar along one side for added strength between teeth. The next 4 teeth and the pick-up tooth are one-piece with the piston body and also feature heavy-duty blocks on both sides of the teeth to prevent teeth-shearing and to distribute force.

The 2nd tooth has already been removed to help you correct angle of engagement (AoE). The piston guide rails have 2 sections on each side cut out to reduce friction and overall piston weight. The front of the piston is also quite thick meaning that the impacts of the piston head against the piston can be better dissipated. We have seen stress fractures at the heads of other pistons and having a thicker head with better materials prevents this piston from suffering the same.

Compatibility: Due to the reinforced nature of this piston, the width of the teeth of your sector gear must not exceed 4.52mm. Also, be cautious when shimming the sector gear and ensure full contact is made between the piston and sector gear teeth.

Lonex Piston comparison and compatibility

These pistons have been tested to work with Lonex, SHS, VFC, Modify, XYT, Systema, Classic Army, Siegetek and King Arms gears.

They are NOT compatible with TM, KWA, and Guarder sets. Please let us know if you have tested other gear sets which may/may not work with this piston and we will update this page.

NOTE: Do not use this piston without swiss-cheesing or lightening the piston assembly if you're doing a high-speed build. Due to the robustness of the piston, it is significantly heavier than others and may cause pre-engagement issues leading to premature piston and/or gear failure.
