I have a new unfired Heckler & Koch MR-556 upper receiver group for sale. Includes the complete 16" barreled upper, internals, Hk diopter iron sights, manual, receiver lock, and battle grip.
This upper IS compatible with all other standard AR15 lower receivers
Buyer has the choice of a PRI Gas-buster charging handle or the standard charging handle…whichever they prefer.
$1,900 shipped and not interested in trades.
Thanks!!
