Heckler & Koch MR556-A1 Finally Arrives- Serial No.500 Pics

[OnPointFirearms]

What a surprise! Check out what showed up at the shop yesterday afternoon: serial# 500 of the new HK MR556-A1-- "Mister Five-Five-Six" himself. It's an Easter season miracle. Alleluia!

After breaking it down and giving it a thorough inspection, the beauty of this new Heckler & Koch masterpiece is really in the subtle details:

- detent springs built into the receiver's take-down pins
- beveled magazine well
- ambidextrous safety selectors that can be engaged at all times and don't - German proof stamps everywhere you look
- awesome HK-logo'd buffer, along with its spring and robust buffer locking pin
- polymer dust cover was odd, but I'm sure HK had a good reason for designing it that way
- thick and heavy contoured 16-inch, 1:7 twist barrel, hammer-forged, and is NOT chrome-lined. Also, the muzzle end has been swaged to achieve a slightly smaller diameter
- bolt is spring loaded into the carrier group and stays in the extended position-- making assembly easier than a conventional BCG
- captive firing pin retaining pin, so you won't have to worry about losing it

Here are the pics. Enjoy!

Please tell me that's grease seeping out from between the upper and barrel extension.

So, is HK upper compatible with regular lower receiver?

[Mr. Goodtimes]

why did HK not chrome line the barrel?

What a surprise. No as they say around here: "Go shoot it!"
