Out of EXTREMLEY popular request, we are bringing back the MP5 platform, known officially as the CYMA SMG9. There are slight differences present. This doesn't utilize a proprietary MP5 gearbox, this uses CYMA's Standard Platinum V2 Gearbox. CYMA's SMG9 also doesn't utilize a standard MP5 stock, it comes with 3 options of stock's listed below. We normally would have 2 variants of triggers, one being the high speed variant with a Maxx Adjustable Speed Trigger, and another with Perun's 2 Stage Clicker Trigger. However since this platform has it's own proprietary trigger we are only offering this build with the Perun 2 Stage Clicker Trigger. 
Though CYMA got many things right with this platinum series of gearbox, we also did see areas where we considered to be cutting costs unnecessarily. "Low profile" bearings should -always- be avoided whenever possible, as they rate about 33% weaker than normal. CYMA had an odd choice with their sector gear. We noticed some excessive FPS drop off due to the sector/tappet timing being off. Here at Umbrella we specialize with high ROF builds and this is no different, our specific modifications allow for accurate fire in either Semi or Full Auto fire. 
This build gets the full love that our other CYMA's get,
