I have a Parallax Tactical Extreme Super Light Low-Profile Steel Front Adjustable Gas Block - .750 on a 300Blackout Barrel and the Adjustable Front Mounted Set-Screw is missing.

I need to get a replacement set-screw but need to know the length, diameter,and threads per inch in order to get a replacement set-screw.

Can anybody who has one or has access to one measure theirs and let me know?

I am dead in the water without that dog gone set-screw.

Have a Fastenal nearby you can take the gas block to? They stock set screws and can figure out the size.

No, unfortunately I do not.

Most Ace hardwares do too, amazing what can be found in them.

Obviously, the diameter and threads per inch must match but how do I know the length of the set-screw or does the length not matter?
