king arms sig 556 shorty top rail loose

[steven_191]

The top rail is actually in two parts. The front half is only held on by a screw at the front end and the back just sits on top of the gun. Apart from replacing the whole thing for a single piece to make it more sturdy can you get a sort of link piece that can hold the two rails together.
Everythig seemed to be getting a bit loose. I've started stripping it down to see what I can do. Seems like mostly just screws needed to be retightened but they are all those crap corse thread type like wood screws. I do t think they will stay tight for long.

Anyone else had one that keep going a bit wobbly?

Use some loctite on the screws, if it is good enough for NASA and Boeing it should do your Sig

Yeah I was going to use loctite. I found it was mostly due to loose grub screws.
