Looking to fund another project, so this fantastic upper is up for sale.
Sig Sauer no longer sells these uppers for converting your AR15 to the cleaner running piston system.
Comes with extended handguard, generic ambi CH and semi-auto BCG. NO SIGHTS.
This upper has a 14.5" barrel and was pin-welded with a Fortis muzzle brake to achieve 16" OAL.
The bayonet lugs were also shaved off for NJ compliance. $850 shipped insured.
Sig Sauer 516 Gen2 14.5" Barrel Upper Receiver Assembly, Semi-Auto. The SIG516 14" upper allow operators to upgrade
their current AR-15/M16/M4-type rifles from direct gas impingement systems to the SIG SAUER advanced short-stroke pushrod system. This advanced operating system reduces carbon fouling, excessive heat and unburned powder
in the action, ensuring reliability and function that is unmatched. 1/7 twist, 1/2x28 threading, 5.56 NATO chamber.
For best results use an H buffer (not included).
Works flawlessly on any AR15 lower to convert to a piston operated ejection system similar to the HK416 or LWRC M6.
I accept discreet PPFF (or you pay the +4%) or Zelle. First "I'll take it" post gets to take this home. Shipping is CONUS only.
Email works best for any questions. Thanks for looking.
