Tips For Removing Stripped Pistol Grip Screw?
 

Trying to swap out an old grip on one of my M4s and I'm having trouble removing one the screws because it seems it was way over-tightened out of the box. I can see / feel the head beginning to strip because my screwdriver is losing grip and I don't want to wear this thing down any further until I've figured something out - If it helps, the gun is a VFC VR16 CQB II (Mk.18)

Any tips on the best way to remove a stripped phillips-type screw from inside the confines of an M4 pistol grip?

And also, what are the screw-specs for this type of screw so I can go get some better ones from the hardware store?

[CLARIFICATION] - The screw I'm referring to is not the grip panel screw that lets you access the motor, it is the screw that attaches the grip to the gun itself after you've removed the motor from the inside

Many thanks in advance!

If it's already stripped out, this is your best bet, and then find some replacement screws.

Canadian Tire should have them. They've saved a gearbox of mine before.

The old rubber band + screw driver trick.
If you're in a pinch and need to improvise something try it:

@ Full-Auto-Seer - Will keep that in mind! The screw still has a bit of meat left in it so I may try to see if I can get some grip using a torx bit. Do you know the size and dimension of the screw that's typically used to hold these M4 grips?

@ Cr0nik - Tried that, but unfortunately no dice. May also try aluminum foil as well to see if that works to fill in the gap a bit more

Thanks!

I don't know the type of screw exactly, but you can probably check at an airsoft/hardware store to try and find screws with the same gauge and pitch.

Yeah, I did some asking-around and as it turns out, you can actually use the same kind of screws found in PCs. Did a test earlier today on my grip and it works like a charm, so the replacement has been taken care of. Now I just have that one stripped screw to content with lol

Part one. Do the other 3 bolts up tight.

Part two. Use a solid screwdriver. No little thumbwheel ones.

Part three. Clamp or secure the receiver so you can use 2 hands on the screwdriver.

Part four. Lean your weight with your palm on the driver so it can't cam out of the head and slowly wind out the damaged screw. Throw it out so you're not tempted to use it in a pinch. You'll have 3 good ones to use as comparison.
