"The 8A is a prototype of what became RIA 7 and was never produced commercially. Available as a limited run only, this SMG is incredibly effective."
―Official Description

The RIA 8A is a Prem submachine gun. It costs 80 NK coins. Despite being a Prem gun, the RED RIA 7 can easily compete with this gun.


This new weapon came out from the 3/3/16 update. It has average DpS for a SMG, yet falls under other SMGs whenever compared to the RED and Selection 004 versions of other SMGs.

The RIA 8A, as said, was a prototype of what became the RIA 7. The RIA 8A is better in almost all categories when compared to the normal version and the RED version of the RIA 7, and is cheaper to Augment and use then the Selection 004 RIA 7.

It isn't recommended past level 30, due to many other guns found at that level doing double or triple the damage this gun does, and it being the weakest Prem SMG and possibly of the whole Prem collection when considering DPS.

The upsides of this gun include the standard extras that come with all Prem, being free augmenting to reach its full potential, cheap ammo, and with using this weapon gives extra EXP for the SMG Mastery and for leveling up.


Similar to RIA 7 & RIA T7RIA 8A is modeled after MP5. However, RIA 8A appears to be closer to MP5 than its line-mates as having a large handguard, almost identical sliding buttstock, which makes it a re-designed MP5 other than a gun based off MP5. As a Prem, it has gold-chromed/golden parts with hexagon patterns.


  • It is the lightest PREM weapon in the game, mainly due to it being an SMG.
  • It is quite strange that a Prototype could be more powerful in every aspect, and be reduced to a lower standard, even for cost reasons.
    • This is likely due to common misconception built through various media that a prototype is extremely powerful, to the point where it bent the definition of the word itself.
  • Like the RIA 7, it bears some similarity to MP5.
