Arsenal Page 30 lists the minigun rules and states that any machinegun can be made into a minigun however there is no cost listed. Additionally what would be the most likely rules for a high velocity minigun?

Anybody have a clue or an official ruling?

On looking back, my post didn't really help, so I nuked it from orbit.

Sorry for the bandwidth.

I would place the cost at about 3 times that of a manufactured minigun before availability reduction expenditures, honestly. All of that custom machining, shipping of parts, etc would be a complete pain in the hindparts. It's not like you can go down to your local gun shop and order minigun barrels, after all.

Well It also lets you design you own weapons... adding mods and renaming. But darn it I want My Troll Sniper wants his high velocity heavy minigun with apds.

High Velocity and Minigun wouldn't stack. You'd just get the minigun effect.

Based on a thread I posted a while back on this same question, it seems that there's no official way to make a minigun.

Macguiver could build one out of some tubing,an old washing machine and a roll of duct tape for about 20

Cost effecient and man portable

No official ruling, I'd just go with the same slots and cost as the HVAR mod, and add in a little GM approval
