QTD-12

The QTD-12 is a rarely used assault rifle of the Quantonian Empire. This rifle was designed 20 years after the development of the QTD-07 on the 07/03/1578. 
It is a bullpup assault rifle with a cocking handle on the right side and a scope rail placed on top. It is a very sturdy weapon and has a fire rate of 600 rounds per minute, These rifles breaking are extremely rare thanks to their mechanic designs. 
The QTD-12 has quite a lot of recoil but is a fairly accurate weapon. The weapon has easily accessible mechanisms in case the gun breaks, so repairs are easy.
The QTD-12 today is sometimes used but not very often as they are shadowed by the mass-produced QTD-33 which beats the QTD-12 in every aspect.
The QTD-12 is the kind of weapon you would give your 18-year-old son for Christmas.
