The ornamental LATRON PRIME exploits ancient Orokin technology to get a slight damage increase over the standard LATRON.
The LatronPrime features higher base damage and critical-hit chance than the Latron. The Latron Prime was added into the game in Update 8, becoming one of the first prime weapons to be avaliable to non-founders.
See the user build section for builds using this weapon.
On top of the fact that the parts come from the Void, the receiver seems to have a very low drop rate, which makes this weapon very hard to acquire. But, as of Hotfix 220.127.116.11, the Latron Prime Receiver drop rate was changed to "Common" for Tier 3 Exterminate Missions.
As of update 10.3, The Latron Prime parts were moved to T3 survival.
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.
