MEDIA Day Shoot: New MR762A1 LRP .308 from Heckler & Koch

There were many semi-auto “tactical” rifles on display at MEDIA Day 2013, but one that caught our eye was the new MR762A1 LRP from Heckler & Koch (HK). The HK MR762A1 LRP (“Long Range Package”) looks similar to the H&K G28 rifle, Germany’s new Designated Marksman Rifle. But the G28 has a steel upper receiver, unlike the MR762A1, which evolved from the HK 417.

Bedecked with quad rails up front, this black and tan rifle screams “tactical”, yet it is surprisingly comfortable to shoot. The grip is comfortable in the hand and the thick rubber buttpad on the adjustable buttstock did a good job of mitigating recoil. Jason said the trigger was crisp and the gun was very accurate. With a gas-piston system (rather than direct gas impingement), this rifle runs very clean. The proprietary, polymer HK magazine worked perfectly with zero feeding issues. We liked these better than the metal mags we’ve tried on other makers’ AR10-type systems.

The MR762A1 is a direct descendent of the HK416/417 series, only in a semi-automatic rifle configuration developed for civilian users. The MR762A1 LRP employs the same HK proprietary gas piston operating system found on current HK rifles and carbines, using a “pusher” rod in place of the gas tube in the original M16/AR15/AR10 design. According to HK, the op-rod design “virtually eliminates malfunctions common to direct impingement gas systems since hot carbon fouling and waste gases do not enter the receiver area. The MR762A1 stays cleaner, reducing heat transfer to the bolt and bolt carrier, and drastically reducing wear and tear on other critical components.”

The MR762A1 uses the same 10- and 20-round translucent polymer box magazines made for the HK417; a 5-round magazine is also under development. Additional accessories and add-ons for the LRP variant of the MR762A1 include an ERGO Pistol Grip from Falcon Industries, the same Blue Force Gear sling used on the HK M27 IAR supplied to the USMC, and an OTIS cleaning kit. The rifle package, complete with one 20-rd mag and one 10-rd mag, is shipped ready to use with the scope attached in a 42″-long Model 1720 Pelican case.
