Back in the day, Blazer Rifles were awesome because they did regular Laser Rifle damage twice for one to-hit roll. Inexplicably, AToW increased the Armor Penetration by one, and left the Base Damage the same. Doing the math, the old school way isn't terribly unbalancing (in my estimation) so here's my take (with TW scale conversions for both the Blazer Rifle and Blazer Pistol):
Blazer Rifle
TL: D
Availablility/Legality: C-C-D/E
AP/BD: 4E/8
Range: 60/205/465/1100 (Standard Laser Rifle range)
Shots: 10 PPS
Cost: 2,190 C-Bills
Weight: 7 kg
TW Damage: 0.56
TW Range: 2/4/6 (Standard Laser Rifle range)
Doing the same thing to the Blazer Pistol yields:
TL: D
Availablility/Legality: C-C-D/E
AP/BD: 4E/6
Range: 15/35/80/225 (Standard Laser Pistol range)
Shots: 4 PPS
Cost: 3,000 C-Bills
Weight: 2 kg
TW Damage: 0.42
TW Range: 1/2/3 (Standard Laser Pistol range)
