That screw could very well be the wrong screw the original had failed and this one came from Numerich a long time ago. But, there isn't a hole all the way through to the barrel. I would have to drill a hole to get that done.
It's my experience that quality varied a lot. Also the engineering was poor on early Marlins.
I'm not happy with ones I've owned.
