There is nothing better than new airsoft kit being released, unless of course its free! MadBull airsoft has a free give away promotion on their new Piston range.
The FREE piston tryout event starts from now (4/15, 07) (You have to pay shipping cost.) I already received tons of email regarding to this event. Quantity is limited to 300 pcs. First come , first serve.
You will not regret to try our new design piston!Key feature: “3” “closed” “Lubricant Grooves” which can hold more grease than anyone else. (Note: Systema piston grooves is open design.)
Other Features:(1) “7” Steel Teeth: NC process with maximum strength. Most of other pistons only have less than 7 teeth.
(2) Light material: Polycarbonate
