We have posted news about the F-Factory MUR-1 for the new generation blowback and recoil AEGs from Tokyo Marui that will be made available in October 2015, but before that a lower receiver will be coming out ahead of it. Laylax also announced a series of lower receivers from F-Factory for the new gen AEGs will be coming out in September. You can select between Colt, Stoner or Noveske markings on the lowers or even have a blank version.  This is compatible with the Tokyo Marui New Gen M4 SOPMOD, CQB-R, and SOCOM Carbine.
