The ornamental Latron Prime exploits ancient Orokin technology to get a slight damage increase over the standard Latron.
The Latron Prime is an ancient Orokin semi-automatic rifle that serves as an upgrade to the Latron, features higher base damage in the form of more Puncture damage and critical-hit chance. Much like the standard variant, the Latron Prime holds the same strengths, making it an excellent upgrade to the Latron.
The Latron Prime was added into the game in Update 8, becoming one of the first prime weapons to be available to non-founders.
The Latron Prime and Reaper Prime were available after Update 8, although DE had previously mentioned not releasing the weapons on U8. This may be because of the many times U8 had been delayed. 
Latron Prime is the first primary weapon to be a Prime.
As of Update 8.3, the Latron Prime's body and energy color can be colored.
The Latron Prime has a distinctive firing sound that might suggest it uses energy or electronics in firing.
The Latron rifles are most likely classifiable as battle rifles, if not designated marksman rifles (DMR).
As of Update 14.5 the Latron Prime has been given a new reload animation.
The new reload animations suggests that the Latron Prime is a lever action rifle, as the animation shows that you have to pull the lever (golden bar near the trigger) to open the top of the barrel before it is closed again as the weapon is reloaded.
However, unlike a Lever Action rifle, you do not pull the lever to load a new bullet into the chamber after each shot.
