Ejector Plate Fix using flat head screw instead of rivet. Perform this at your own risk!!!!

On one of my GSG's, I used an M2 counter sunk flat head which is just as solid as a rivet. You can get all of the hardware needed for this job at www.mcmaster.com.

Hardware Needed -

Drill Press or Hand Drill (if you feel like you can hold a hand drill straight)
M2x.4 Drill and Tap Set (Drill bit is usually a 1.60mm drill bit)
4mm drill bit
M2x0.4x6mm Flat Head Screw

Finished Product Below

Instructions

1. Drill 1.50-1.60mm (drill that comes with tap) hole in center of circular tab. The tabs are not quite punched in the center so take your time and get the hole centered and straight.

2. Tap the hole with M2x0.4 tap. Use oil while running the tap through the hole

3. Use 4mm drill bit to counter sink ejector plate so that the flat head screw will sit flush with the ejector plate.

3. Use M2x0.4x6mm flat head screw with RED loctite to secure the screw. You don't want to ever have to remove this screw so use RED.

Hope this helps!

That doesn't look like a flat head screw to me

Yep, I was in a hurry to hit the range and accidentally countersunk the wrong hole.
No bigge, that hole isn't used for anything. The pictured bolt is a flat head. The mod has over 2000 rounds fired with no issues.

Great writeup. Since I already have a 4-40 tap and #43 drill bit....would there be any reason not to use a 4-40 instead?

The gun is metric & you're wanting to use a standard thread screw???? You'll be kicked out of the Tactical Club, homes...............
