"Fit just right on my oly arms k16. It was pretty hard to get the gas tube and roll pin in it, but that's all gas blocks."

"OEM - installs on the DPMS perfectly and easily if the old block isn't over-toqued from the factory like mine was. Wish it were longer but that's not an option for the bull barrel. Once I got the old block off the new one went on in less than a minute."
