WTS Custom HK MR556 upper with 416 FA carrier, Troy carbonfiber handguard

6 posts in this topic

HK MR556 low round count upper that I had the barrel tab professionally machined off so a full auto 416 bolt carrier will work. Once that was done I swapped the carrier for a early 416 bolt carrier. Has a Troy Ind. Carbon fiber handguard. This really takes away the front ended weight. $1550 obo Prefer paypal f&f or you pay the upcharge or USPMO.

What is the barrel length, and does the bottom of the upper receiver have the auto sear relief cuts? Do you have the original handguard?  Thx

How about sear relief cuts? I dont know if HK included them on the MR556 or not. If you post a pick of the underside of the upper receiver that will tell the tale. Without the relief, the upper wont close down over a M16 registered receiver auto sear. Thx

No sear cut, my plan was rmto use a dias.  They can be added easily.
