If you use the stock piston head, your fps will on average be about 7-10fps higher than using the Area1000 piston head (at 400fps), but it will not be as consistent. I recommend getting a ventilated bearing piston head. The Area1000 piston head is ventilated but has no bearings.

PDI has no m-rated springs. Wherever you saw that must be a typo.
