The Modify Full Teeth Piston is constructed from quality polycarbonate and will work with all upgrade and standard springs. Modify series of upgrade parts are compatible with most major brands of AEG. You can expect the same level of quality from these parts as Guarder and Systema parts for a fraction of the price.
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.
Was pulling a guarder SP120 for about 25k rounds... at about 15 rounds per second in a version 2 with a duracon piston head and brass cylinder head (No cushioning)
now holding up to a SP130, with no signs of it being ready to explode yet.
So whoever says not to use this with an M120... you're wrong, it holds up fine.
Only sign of wear is that the second to last tooth is completely gone... which is usual.

Overall a good piston for the price. Ive been running these in 3 of my guns for a while now and havent had any real problems with m110 springs and 7.4 lipoly batteries. Ive put about 20k through my m4 with one of these. But be cautious if you are using a battery anything larger than 9.6v, i did have a spell where i broke two of these when running 11.1v batteries after about 5 thousand rounds each.
Will not withstand extremely high rates of fire even with back teeth removed

Warning: this piston may be very durable, heat resisrtant and light but don't be fooled it would be wise to use a m100 spring or less you should use a max of m120 but above that the piston may break so be careful and if you want to have higher than a m120 spring I recommend you buy either a systema aluminum piston or a jbu aluminum piston with an additional reinforced gear set for it!
also if you want higher than a m120 spring it would be wise to get a 7mm or 8mm reinforced gearbox, good bushings (oiled for pros and oiless for anyone playing normal games) it would also be wise to get a metal spring guide, a systema super torque gear set, grease for after every use/game. And to top it off it would be good to have or buy a new cylinder, a silent piston head, a aluninum air nozzle and a high torque src motor.
Then once you have bought all that just get a precision barrel that is only 6.04 mm no less and no more because when you put bb's through it their going to shoot so fast that a stock barrel would make the bb blow up or fly in random directions.
I really do not reccomend putting this piston in a sniper or m16 or any long range guns. Because you won't be able to have a high fps and you will have less range I only recommend putting this in a mp5, a mp7, a ump or a m4/m468 (cqc) because it will increase the rof.
But take away the range and accuracy it would only work on a cqc gun very well if you include the following:
1.) A silent head set
2.) A m100 spring
3.) A 7mm or 8mm reinforced gearbox
4.) A systema precision inner barrel (6.04 mm)
5.) A oiless bushing set (7mm or 8mm)
6.) Src nozzle for your gun
7.) Bore up cylinder
8.) High speed gears
9.) High speed motor
