    Question Rail screw torque spec

    Did some searching, came up empty. Anybody know the inch pounds of torque for the rail screws in the upper receiver? Thanks in advance.

    I just tighten them up fairly snug with blue locktite. Don’t do the one by the detent too tight or it won’t slide like it’s supposed to.

    With blue locktite you can actually get them in there pretty tight so they won’t fall out.

    Will do, thank you!

    I was at the range last night shooting my new 6.8 ACR and I looked down and saw the middle screw from the left side laying on the bench.

    Just be careful, you can tighten them so tight that they need cut out. Which if you are never going to remove them isn't a big deal

    Yup will do. That's why I was asking for torque specs as I have a tendency to over-torque things otherwise.

    I still can't believe that Bushmaster doesn't Locktite those screws in at the factory and are still clueless that those commonly fall out.

    They actually do put some sort of thread locker on them or at least most of them. It’s either not enough or not all of them get it.

    Now if they could get the rockset on the hiders that way I’d be happy.

    Most of the rail screws are 8/32 IIRC. I am not sure what BM/Rem use in terms of sourced fasteners, however it you start with Low carbon spec and use some thread locker you should good to go.

    Good to know! I didn't realize our guns have this issue. I'll check the Loctite as soon as I get home.
    Do it or don't!
