Very glad I bought this item. HKParts' shipping was fast as always. Item arrived in great shape. I oiled it up and wiped it down and it was ready to go. Provides much needed additional rail space for iron sights, optics, lasers. Definitely recommend it to any MR556 owner. Just remember to clean the top muzzle end where gas kicks out. Rail is build like a tank.


"Extended Rail is very practical"

This Quad Rail is hard to find, but it is very practical to use. It not only provides the HK416/MR556 owner with additional options to reposition a vertical grip for comfort and control, but provides aditional surface to mount extra aiming devices. It is simply PERFECT!!!

If you want the ability to utilize a dominant grip on your rifle and you have a 16inch 416 variant than this is for you! I'm over 6,5 and needed a little more ability to extend my arm out and the shorter or standard rail was cutting it a little short, it was no big deal but this makes it fit just right, and allows me to dominate and control my rifle much more, especially in room clearing and helps tighten up my groups. A very needed product by HK!
