The New Heckler & Koch MR556A1 Upper -The Firearm Blog


Our Photo Of The Day is in flames! You’re looking at the latest Heckler & Koch MR556A1 upper. The caliber is 5.56 x 45 mm with a barrel profile with 6 lands & grooves, right twist, 1 in 7″. The sight radius is 14.60″ but you can of course use the Picatinny rail to mount a red dot or a riflescope. Two great optic choices are either the Aimpoint CompM5s red dot sight or the Schmidt & Bender 1-8×24 PM II ShortDot Dual CC scope. This H&K deserves something more than just the iron sights, at least that’s my opinion.

Below you can see the H&K MR556 with various interesting accessories.
