HK MR556 A4 Complete Upper for sale in San Antonio Texas

$1,800.00

I have for sale a brand new never fired HK MR556 COMPLETE Upper reciever. This is the newly released A4 model not the A1.

You can just slap this on any standard AR-15 lower you already own and start experiencing HK' extremely reliable short Stroke system.

I only have pictures of the complete firearm (don't want to take it apart since it's brand new until I sell it) MSRP at HK USA for this upper is 2399 + tax so this is a great deal.

Muzzle device was swapped to a YHM muzzle break but I will include the original bird cage muzzle device it came with.
