I have a Sig 556R and have read that it'd be a good idea to Loctite the top picatinny rail on the receiver. I haven't done it yet but was wondering if there is anything that the Loctite could drip down into and seize up, like the bolt carrier or such, i.e. does the screw hole go all the way down into the inside of the receiver?
