Selling the parts from an old M4 build I had as used as a bundle. Not overly interested in breaking up the lot. I can arrange shipping of these following discussion of costs and fees.

For whatever reason the handguard nut is extremely tight going on to the handguard almost as though the metal work has seized, so I'd recommend either lubing it up, using elbow grease or an armourers tool. The parts have signs of physical wear and tear and from impacts so this is all reflected within the price. These parts can easily be given some TLC and a coat of silk black spray paint to come up as good as new.

I have included photos of the M4 this once was so you can see how it looks when built.

Bundle compromises of:

• M4 Upper and Lower Receiver (APS)
  • Fits V2 style gearboxes
  • Locking Nuts and Pins
  • Charging Handle
  • Dust Cover
  • Fire Selector
  • Magazine Release
  • Inside was dremeled to allow a larger gearbox to be installed. No issues caused with installing standard V2 gearboxes.
     
• Evolution Tech 10" Key Mod Hand Guard (APS)
  • 3 x Removable key mod picatinny rails
  • Handguard Nut
  • Inner end edge has impact marks to the metal work. Can be filed and repainted. Not really noticeable when built as shown in the photos.
     
• RS-2 Collapsible Slim Butt Stock (APS)
  • Easy access to inner buffer tube
  • Has storage within end cap for batteries/MOSFETs
  • QD Sling attachment
     
• 10.5" Aluminium Outer Barrel (Big Dragon)
   
• 110mm Lightweight US Army Silencer (King Arms)
   
• Short Key Mod Vertical Grip (Battleaxe)
   
• Advanced Pistol Grip
  • Motor grip screw got loctited in to place by an old tech. It's at a level which does not cause issue, but you will need to use a solvent if you wish to adjust the motor height. Due to attempts the straight screw head is messy. Solvent and a thick flathead screwdriver will do the trick.
     
• Flip up front and rear sights (CYMA)
