Weapon Compatibility Liberty Eagle

[MasterL410]

Hey there, and welcome to Discovery.
Your tech compatability always depends on your ID. You can find your ID oon another page of your inventory. You most likely use the Freelancer ID, which does not allow military grade weapons or faction-specific weapons.
You want to use civilian weapons. A few examples are: Flashpoints, Debiliators, Purple Goddess Chainguns and Moonblasters. Those should work well with any ID.
But you can also change your ID to fit a ship/weapons you like. E.g. Liberty Navy for Liberty guns. Just make sure you read your ID lines, they are the guidelines for what you can do.
I hope that helped. Feel free to reach out if you have any more questions.
