I have a DPMS Sweet 16 upper. I want to replace the free float tube with a rail. There are 2 set screws on the bottom of the gas block. I got one set screw loose but the other one will not come out. I will use a little heat to break the other one loose. So I'm guessing they are loctited in. If so during re-installation should I use blue or red loctite?
Thanks |
