have a look at this gas block and tell me what you think...

As you can see the "gas port hole" is rigth under the "role pin hole".
The 2 set screw are slop,so is the gas block on the barrel.
No idea what brand it is.
my guess is its an airsoft part. done this way so if can't be used on firearms.

im guessing it might be something life this problem.

The location of the gas hole and roll pin didn't even factor in when I saw the picture.

The fact that the gas block bore is so rough and just garbage should ring the alarm bells long before any other issues arise.

those look like signs of somthing thats been parkerised and stripped a few times, could also be the reason for thr sloppy fitting

This is exactly what I thought too. No WAY that's getting anywhere near an AR15 barrel.

I'm just a dumb carpenter, but that looks like a cast part to me?

it shouldn't be. That is supposed to be a precision bore.

It does look like a cheaply cast part with no internal machining. As stated by the OP, most definitely looks like an airsoft part that's just for looks.
