I'm trying to attach a Magpul barricade stop, and the rear screw needs to be shorter to cear the gas block. Are there any shorter screws available? If this was my personal firearm, I would carefully grind the screw, but I'm installing this for a friend,  and would like the installation to be more professional looking than a ground down screw.
If shorter screws are not available,  then what is the thread size? Also, what is the thread locking compound applied to the threads?

Thanks in advance!

I believe the replacement screw kit MAG615 includes shorter screws.

Cut the screw down with a dremel or something similar, I’ve done that several times for the same reason.

Grind it down, bevel it by holding the threads in pliers and turning the screw with an allen bit. Then heat it with torch til red hot, dunk in oil. Professional AF.

OP, just cut/grind the screw down.
It's hidden and not an unprofessional way to do it.

Put a cup of water near the grinder.
Hold it with bare hands while grinding.
When your fingers get warm, dunk the screw in the water.
It'll never lose temper.

Just heating steel to red and dunking in random oil is a sure way to get steel too brittle, unevenly quenched, and impart unwanted additives. You're also missing the critical step of tempering.
