This is certainly the type of weapons I loved, and they all look awesome.
My opinions:
1st weapon kinda reminded of the Magpul PDW with a mix of the KRISS Vector (due to the slight angled magazine), I guess you haven't figured out a name for this, so I'll name the gun CQB-CS SMG for now, maybe I'll figure a name out of the gun.
2nd weapon is kinda more of a resemblance of the new Combat Rifle CS-OICW, due to it's color schemes and design, but merely a PDW. Another bullpup alike the CQB-CS SMG & Magpul PDW, but I really loved the design. Would love to be using this.
3rd weapon, I understand that you're designating this as a weapon for the Androids (Especially with the T-01187s but SLC-56s are the exceptions), but it also seemed suitable for the Usurpation Forces (Commonly, the Advanced Usurper). I really loved it's design, but does it need to be loaded with another rocket shell after shot? But anyways, best design.
If rating's possible, I would be rating them all 10/10. Your welcome.
