What you want to use is a knurled point/ knurled cup point setscrew; even if using the knurled cup point set screw it is best to make a dimple large enough that the setscrew can begin to enter into the dimple.
If you need a definition of what a knurled cup point is, here you go: https://en.wikipedia.org/wiki/Set_screw
One of the problems is that the hardware stores in my area stock plain cup points, I go to an industrial supply place to get knurled cup points.
The knurled cup points shouldn't be reused, although if the barrel is dimpled and the set screws are secured using blue loctite, it probably doesn't make much difference.
If the gas block is aluminum (use a magnet to check if you are unsure) you might want to replace it with a carbon steel one. These are my go-to: https://algdefense.com/carbon-steel-gas-block.html Of course if you need a pic rail gas block they won't fit the application.

Patriotism means to stand by the country. It does not mean to stand by the President... - Theodore Roosevelt, Lincoln and Free Speech, Metropolitan Magazine, Volume 47, Number 6, May 1918.
Every Communist must grasp the truth. Political power grows out of the barrel of a gun. Our principle is that the Party commands the gun, and the gun must never be allowed to command the Party Mao Zedong, 6 November, 1938 - speech to the Communist Patry of China's sixth Central Committee

A buddy needed help with a DPMS before. He ended up dumping the quad rail and aluminum gas block, and replacing it with a AGB and 10" used ALG rail. The AGB fixed the overgassing, and he lightened up the front end quite a bit. It's his square range barrel burner, which he realizes. He bought it before he knew any better, and has since built a better rifle as a go-to.
