For sale is an excellent condition HK416/MR556 clone upper, 10.4” barrel. About 250 rounds through it. The receiver is a genuine HK receiver, the barrel, BCG, charging handle, gas block, op rod, piston, and barrel nut are all BRN4. The flash hider is a SureFire closed tine Warcomp. Upper shoots perfect suppressed. I recommend 62gr 5.56 with a standard buffer when shooting unsuppressed. $1300 shipped. No trades at this time. Thanks!
