Rail Guns

Overview

Damage Type	Weapon Type
2/3rds Thermal, 1/3rd Kinetic	Hitscan

Good	Not Good
High burst damage at range or up close.	Firing repeatedly will toast your ship. Firing repeatedly will toast your ship.
Canceling SCBs.	Ammo runs low quick unless you take a particular experimental.
CMDRs with good aim who like to destroy modules.	The damage mix means you’re not doing as much damage to shields or hull as you think due to resistances.
Armor Penetration is 100, so you always do full damage.	The firing delay when triggered and the need to release trigger to fire again.
	There are only 3 experimentals that lower heat, so pick one of those.

The two different sizes have different firing rates.

3 shot automatic rail gun.

Damage of 3 shots is slightly more than 1 shot of regular rail.

Very high heat, higher distributor draw.

Unlike rails, fires continuously when trigger is held.

You need to hit with all 3 shots to get comparable Feedback Cascade performance.

High Capacity	Bigger clip, but the damage over time is only slightly higher due to fewer reload pauses.
Lightweight	A good choice on smaller ships if you want to punch above your weight class.
Long Range	Good burst with no falloff, and since they’re fixed weapons you can hit all the way out to 6 km.
Short Range	Very good burst at point blank range, but you’ll have to do something about the heat.
Sturdy	~~No.~~ Actually not a bad idea if you want to cancel most of the heat.

Double Braced	Use a module reinforcement instead.
Feedback Cascade	If an enemy ship is using a SCB and you can hit with this during the spin-up, you will “cancel” part of the shield reinforcement. Lowers heat.
Flow Control	Frees up a tiny bit of power, but there are better ways to do that.
Multi-Servos	Firing faster is not always better, especially with this weapon’s heat.
Oversized	There are better ways to do more damage with rails.
Plasma Slug	Decreases damage by 10%, but you draw ammunition from your fuel supply. Depending on the ship (and its fuel tank) that can extend your fighting time by a lot. Lowers heat.
Stripped Down	Frees up a tiny bit of mass, but there are better ways to do that.
Super Penetrator	Slows your firing rate a bit, but you do damage to any module hit in a straight line. Lowers heat.
