That could be a good reason, my CA M15 has an air leak someplace, as the PDI 140 spring that we put in it is only putting 255fps out the barrel with .25's. We've re-placed the piston and piston head with an all aluminum and re-greased it and still very slow, next up might be the cylinder head and nozzel.
