The FX Impact defines what a modern airgun can be. A rifle without limits. It is a once in a generation rifle. A rifle that advances and evolves to push the boundaries of what compressed air can achieve.
The improvement within the M3 start with its dual regulators. The 1st regulator pre-reduces the air pressure in preparation for the 2nd regulator. This provides less stress on the 2nd regulator and achieves a more constant output pressure with less standard deviations. 38 round magazine in .177, 28 round in .22 / 700 shots per fill in .177, 720 shots per fill in .22
