Heckler & Koch HK416 14.5 inch Complete Upper Receiver Assembly


Genuine German factory new Heckler & Koch HK416 Complete Upper Receiver Assembly Kit


  • Piston Rod Gas System
  • 70% less fouling and cleaning time (< 4 minutes for an HK416, > 12 for an M4)
  • An almost total lack of carbon fouling is present within the weapon during even extended operation. 95% of all carbon fouling, debris and heat leaves the muzzle of the HK416 upon firing.
  • Little or no heat transfer to the bolt parts which results in 3-4 times increased service parts life and little to no requirement to reapply lubricant
  • Ability to fire the weapon w/o lubricant.
  • A lack of lubricant attracts less sand and grit in harsh environments thus improving reliability.
  • Weapon operation not effected by the presence of water in the gas system
  • User removable without tools
  • Same gas system components and gas port location for all barrel lengths (10.4-20)
  • Cold Hammer Forged Barrel with Unique HK Tapered Bore Profile
  • Improved Accuracy
  • Long Barrel Service Life with less than 5% loss in muzzle velocity and accuracy in more than 20K rounds fired!
  • Easily resists damage and/or reduces operator injury from an obstructed bore firing in the evevnt of an obstructed bore (100% obstructed) occurrence (lodged projectile, water, mud, etc.) or excessive firing rates over 500-700 rounds (melt down).
  • Bore and chamber chrome plated for improved corrosion resistance and reduced wear.
  • Improved Accuracy
  • 10.4" barreled HK416's regularly out shoot 14.5" barreled M4's for accuracy - some HK416s with 10.4 barrels shoot @ 1 MOA with match ammo! A randomly selected HK416 with 10.4 barrel from a production lot of more than 300 guns fired multiple 1 inch groups at 100 meters from a rest with match ammo (IMI 55 grain BTHP) during USG acceptance testing.
  • Increased Parts Service Life
  • HK416s selected at random in USG testing have fired 15K rounds and more without a single stoppage or parts failure. In fact one gun was then tested to 30K rounds with no parts failures or stoppages recorded. M4 parts and barrel are expected to last only 6000 rounds or less as per the Armys MIL SPEC for the weapon. (These relatively low numbers are accurate as per numerous reports from M4 users and armorers).
  • ALL HK416 parts are guaranteed for a minimum of 15K rounds.
  • Increased service life helps eliminate failures in combat, time and costs for repeated parts replacement and weapon repair.
  • HK416s have fired 30K rounds in testing without the replacement of a single part whereas an M4 to reach that round count will have replaced barrels and bolts at least 2 4 times, as well as various small parts (extractors, extractor springs).
  • Increased Reliability
  • HK416s have fired more than 20K rounds without stoppages or parts failures, with NO cleaning or lubrication applied during those 20K rounds
  • Bolt Carrier Bell Design for increased function and reliability
  • Bolt
  • Does not require extractor removal for cleaning
  • Has support lug on extractor (and barrel extension) to limit excess compression of extractor spring
  • Bolt head supports the cartridge case head
  • No gas rings required
  • One-piece Piston Rod Carrier Key
  • Improved reliability and component service life
  • Firing Pin Safety
  • Prevents slam or drop fires and primer indents during chambering
  • Higher Cook Off Rate (> 250 rounds versus < 210 for an M4)
  • Free-floating User Removable 4-Quadrant Rail System
  • 100% return-to-zero/bore sight retention
  • Allows user attachment w/o tools of US Army/HK 40x46 mm XM320 Grenade Launcher Module (GLM)
  • Barrel Exchange by Armorer in less than 4 minutes
  • Headspace automatically fixed with install
  • Longer (10mm) Barrel Threads on Upper Receiver
  • Improved Barrel Retention
  • Improved Accuracy
