CYMA SMG5K Extended Top Rail Mount with M-LOK

Code: FBP4030
  • Mounts to MP5K/SMG5K receiver 
  • Has both Picatinny and M-LOK slots
  • Robust Alloy construction with steel screws

One of the few problems with old-school cool like the SMG5K series of AEGs is that you are rather limited in rail mounting space, meaning your mission essential equipment that makes you a true operator has to be left behind. Ask the US Navy SEALs, they are known to use pipe clips and zip ties to attach rails to their MP5SD6s. You no longer have to resort to this pure bodgery, with the Extended top rail mount from CYMA you now have a Picatinny scope mount with forward M-LOK sections for tactical weapon lights, lasers, battery boxes, or anything else you need. This is all kept at the 12 o'clock position, keeping your ambi friendly SMG just that.
