You'll need maximum ranges

Range diffusion? maybe on the Maser but certainly on the pod laser.

As specced you're giving a MHS:1 weapon a greater advantage over a HS:5 frigate's forward firing cannon, the only canon battery weapon that comes close is the MHS:5 rocket battery (at same damage albeit at less than a third of the range. In short MHS:1 for a 2d10 battery weapon is severely unbalancing the game, the civilian ship modification rules would allow warship grade weaponry by simply using three of these for every LB the ship could originally accomodate. I mean imagine the Gullwind from SF/KH1 with three of these 2d10 weapons replacing its single LB, you could easily take on a frigate with a small freighter...a HS:12 freighter could mount six of these and take on a heavy cruiser or battleship.

The original Pod Laser in Dragon Magazine cited the system as "taking the guns from a laser battery and mounting them to a fighter". Range was nearly halved to 5 (from the LB's 9) which is fine for something ailing from an MHS:3 system being utilized as a MHS:1 item. As such I have a "pod laser turret" in my game that does the same 1d10 damage but with a range of 4. It's all you need for the anti-fighter role these systems are designed for, fighter craft have speed and maneuverability to get in and out of range easily enough...it's the bigger/slower barges that need longer ranged weaponry to counter their lacking performance.
