Heckler & Koch MR556A1

The Heckler & Koch MR556A1 is a semi-automatic rifle that is a direct descendent of the HK416. It has been developed as a premium level commercial/civilian firearm with match rifle capability. The MR556A1 uses the HK proprietary gas piston operating system, which employs a piston and a solid operating pusher rod in place of the gas tube normally found in AR15/M16/M4-style firearms. This method of operation virtually eliminates malfunctions that are common to direct impingement gas systems since hot carbon fouling and waste gases do not enter the receiver area. The MR556A1 is produced in the USA using American and German made components. It uses many of the same assemblies and accessories originally developed for the HK416. The MR556A1 also uses a German-made barrel produced by Heckler & Koch's famous cold hammer forging process. The highest quality steel is used in this unique manufacturing process producing a barrel that provides superior accuracy and long service life. The thick, heavy contour 16.5-inch MR556A1 barrel also contributes to its excellent accuracy. A precise enhanced two-stage trigger adds significantly to the accuracy of the MR556A1 and an extended latch charging handle makes operating the rifle with a telescopic sight easier. The MR556A1 is designed to function with a wide variety of high quality 5.56 x 45 mm ammunition, and also functions reliably with most quality Caliber .223 Remington ammunition.

I was looking for a new rifle and I found the Heckler & Koch MR556A1. It's a great rifle, but I didn't want to spend that much money on it. So, I started looking for other options and found this compar. It's not as good as the H&K, but it's still a really good rifle.

The HK MR556, civilian model to the HK416, is a fi is Heckler & Koch MR556A1. It's a great rifle for those who want an AR-15 but don't want to deal with the hassle of registering it as an assault weapon. The rifle has been around for over 10 years now and has been proven to be reliable and accurate.

I have had my Heckler & Koch MR556A1 for over a year now and it has functioned great. I have never had any problems with the gun and it has always been cool, even when I fire off a lot of rounds. The only downside is that the trigger is a little stiff, but that's not really an issue for me.

I've been using Heckler & Koch for over a decade now. I have never had any issues with the quality of their products. The MR556A1 is one of my favorite rifles. It's lightweight and accurate, and it's perfect for long range shooting.
