Issue with Ruger 9mm PC carbine M-Loc Forend Removal

[bykerhd]

I removed the M-Loc forend off my new 9mm PC carbine yesterday to install a hand stop. An issue came up I was not expecting.
The four 1/8" inch Allen screws holding the forend on were horrifically tight.
I had a good quality T handle Allen wrench which was twisting but did the job. All four came loose with a very sharp, scary snap.
Tightened by King Kong was my initial thought but then I found evidence of what appeared to be RED Loctite ???
Why would they use that stuff on a part meant to be removed ?
I was surprised to find the barrel to be fluted and it and all steel parts there in need of a serious wipedown to clean and protect them.
Any similar experiences out there ?

I haven't taken mine off yet but I need to. Now I know what to expect.
Thanks for the heads up.

Hopefully you will have an easier time.
A good quality, hopefully NOT Chinese 1/8" Allen wrench is needed for the forend screws and you will need a Torx wrench for the front sight screws. A small Torx wrench but it was in my odd-ends box and likely came with some scope rings so I can't tell you the size.
Good luck.
I did not use any thread locker to reattach my forend,, just snugged down.

Hold a pointy ended soldering iron against the screw head for 30 seconds.

I've done this when a neighborhood Bubba has used red locktite on EVERY bolt on their Harley. One goober had even used it putting on the air cleaner cover.
