CYMA 20mm Picatinny Railed Gas Tube for AK47/74 AEG

Code: FBP1180
  • Aluminium construction
  • Mount red dot sights, flashlights etc on your AK
  • Compatible with CYMA CM.04x series, LCT and VFC full length AKs

If you want to add some extra accessories to your AK but you approve of neither top cover mounted optics nor the Russian side rail, this railed gas tube should do the trick! Based on the real steel UltiMAK design, the CYMA 20mm Picatinny Railed Gas Tube for AK47/74 AEG replaces the gas tube and upper handguard of your AK AEG with an aluminium enhanced gas tube with a 20mm Picatinny rail milled into its upper surface.

This style of rail has found its way onto many AKs used in the hands of both PMCs operating in the middle east and civilian tactical shooters in the US and is a great way to mount forward mounted red dot sights and tactical flashlights without doing anything weird to the receiver itself. This part is designed for the CM.04x series of AK AEGs from CYMA but will not fit AKS-74U AEGs due to the length.
