Photo Of The Day – As you already know, the new Heckler & Koch MR762 A4 is here. Although it may look very similar, it’s quite a jump from the previous A1 version. For the MR762, the caliber is obviously 7.62x51mm and the barrel length comes in at 16.5”. The stock is the HK416 slimline, with nine positions. If you like a sling, there’s an M-LOK interface with integral ambi QD cups. There’s an adjustable gas regulator for shooting suppressed and unsuppressed.
