The Mad Bull Full Teeth Max Piston is one of the latest parts available in the series of upgrade parts manufactured by Mad Bull airsoft. This piston has 3 lubricant grooves designed to.

"7" Steel Teeth
3 Lubricant Grooves
The use of aftermarket airsoft parts is not an exact science. Some parts may require fitting even thought they were designed to fit without modification. Professional installation of upgrade parts is highly recommended.

I bought this off a different site...same price though. I've put at least 4000 rds through it, and it's still in pristine shape. My gearbox has an M130 spring and reinforced gears in it. My friend bought the same one, but his had a M150 spring. Obviously not good for heavy springs.
Durable with M130 spring
Breaks easily in guns with M140+ springs

It was good for the first 300-450 shots..... Im using a systema turbo(blue), high speed gears, m120 spring and a 9.6v 3600mah battery... I was getting 30-1million rps i dont know what it exactly was during that 1 hicap.... then in the next like 50 rounds of a new hicap the back or last tooth of the piston broke off.... i took it apart to not only realize that obviously the piston broke (had happened before with the piston that came with the gears) but the stock gearbox had cracked right in front of the cylinder head....now i got to replace that to....
was extremely awesome and had hi hopes for this one
not good for my hi speed setup you MAY have better luck

I've had this piston for less than a week (a week!) and no skirmishes, just target shooting in the garage. After less than 2000 rounds, the 'steel teeth' rack broke into three pieces, one tooth, three teeth, and the rest. Using a modify aluminum piston head, PDI 150 spring, steel gears, and shooting 387-400 FPS, this piston will NOT withstand the force. I was sorely disappointed in the metal teeth, which, at this price, may actually just be pot metal, examining the shards/ edges. Now I have to look for another piston. My piston head is screwed up too now _._
Polycarbonate teeth were ok
Metal teeth fragmented, hence the thing is useless.
