The Rifle's appearance and most of its weapon statics are quite similar to the M4A4's albeit with minor differences, with identical price, spread, penetration power, and armor penetration.[2]
It has less inaccuracy while firing, being on ladders or moving. Even less while crouching albeit with more accuracy while crouching with the alternate firing mode.
It has a higher speed reduction (220 units/second against 225 units/second)
It deals less Damage (30 vs 33)
It has a longer recoil recovery time (for both standing and crouching stances)
The weapon, being a placeholder, is not team exclusive.
