    Is there a Torque Spec for this bushing on HK416 and MR556 uppers?

    I believe this bushing is now secured in a way that you will hardly ever see it come lose. I have not seen or heard about that one ever being an issue. That said, we have those pinned bushings for a couple of years now and not heard or seen a case of this being an issue part at all.

    I think the bigger reason for the change was not needing a nice deburred interrupted thread for the barrel nut.

    Thanks for your response!

    I removed this bushing from my MR upper during a refinish. Upon install I snugged it up but was curious if there is a posted spec. If there is I will make sure it gets torqued.
