208 SWEEPSTAKE FOR HK MR556 A4 COMPLETE 5.56 NATO UPPER 11"

This is one entry into a sweepstake for a HK MR556 11" complete upper in 5.56 NATO! The winner will be chosen randomly from a spinning wheel. The sweepstake will close once all entries are filled, or after Nov 30, 2025. Void where prohibited. Must be 21 to win! All federal and state laws apply. THIS IS NOT A PURCHASE OF THE FIREARM. IT IS ONLY AN ENTERY INTO THE SWEEPSTAKE!

The MR556 upper receiver kit has been updated to include all the new A4 features, including new barrel profile, adjustable gas block, handguard and more.

This kit includes a complete upper receiver/barrel assembly, allowing Mil-Spec 5.56mm AR-style rifles to be retrofitted to HK’s piston and pusher rod system. This system utilizes a piston and a pusher rod in place of the gas tube normally found in AR15/M16/M4-style rifles. This closed system virtually eliminates the malfunctions that are common in direct-impingement gas systems, since hot carbon fouling and waste gasses are not propelled into the receiver area to operate the action. This is the same key feature critical to the success of the HK416 used by elite military and law enforcement customers.

There will be a total of 150 available slots through the website plus the AOMOE via swag, mail in, and other means of entries.

Your phone number, first/last name, email, and SKU of sweepstake item MUST BE INCLUDED to receive the free entry. Request must by TYPED. One free entry per customer per sweepstake.
