M41A Pulse Rifle: Bonus +1, Damage 2, Range Long, Weight 1, AP and full auto
M42A Scope Rifle: Bonus +1, Damage 3, Range Extreme, Weight 1, AP
M41AE2 Heavy Pulse Rifle: Bonus +1, Damage 2, Range Extreme, Weight 2, AP and full auto
Balance-wise and thematically, the stats seem a bit off. My suggestion would be to make the sniper rifle heavier with the same damage as the pulse rifle, but higher bonus and potentially a "Scoped" special attribute and increase the damage but decrease the range of the Heavy Pulse Rifle, like this:
M41A Pulse Rifle: Bonus +1, Damage 2, Range Long, Weight 1, AP and full auto
M42A Scope Rifle: Bonus +2, Damage 2, Range Extreme, Weight 2, AP and Scoped
M41AE2 Heavy Pulse Rifle: Bonus +1, Damage 3, Range Long, Weight 2, AP and full auto
Scoped: Gain an extra +1 when aiming at Medium range or longer
I will probably house rule this, but any comments are of course welcome, including from Fria Ligan on why they are given the stats they are, Thomas
Edit: forgot to up the bonus of the sniper rifle, fixed
