Damage is above average at a base of 69.
Rate of of fire is 800 RPM, above the average and should be plenty for crit fishing/DPS.

The concealment on the perfectly normal MCX is fantastic at a base of 25, with a few mods pushing up the concealment even further. You can easily push the weapon into the 30s in concealment.

Stability is average at a base of 56. Combined with lower than average kick values, and the perfectly normal mcx will easily stay on target.

Accuracy is slightly above average at a base of 56, but you dont get many ways to increase accuracy further. True to the nature of a suppressed MCX chambered in .300 Blackout, you should be using this up close and personal to sneak up on enemies, not trying to crossmap people.

Magazine size is the rifle average of 30, with a slightly below average 4 mags (120 rounds) capacity.
Ammo pickup is 3-7, which is plenty as long as you arent missing.
