GSG5 Screw Bit

[Astig Boy]

I lost my GSG5 screw driver set, so now I cant take the rifle apart. Anybody know what type of screw driver I need? The screws sure dont look like regular phillips screw heads. They almost look like 8 star'd heads. Any help appreciated.

like this? if so that is a torx screwhead. anyplace that sells tools should have them, or go online.

just be sure to get the correct size (so local might be best)

Naw, its not a torx head. I have a torx bit set too. The screw head looks like a regular phillips...they say you are not supposed to use a phillips screw driver, which would screw heads in the long run. Hate these proprietary screws!

You might want to consider getting the screw upgrade set from rrages. It replaces all the weird stock screws with regular allen screws.

The screws are not regular phillips heads. They are a special "deep well" version and a regular american phillips screwdriver will strip them out. You can either use a regular screwdriver to remove them once and replace them with the kit from rrages.com (my suggestion) or order a new orange driver from ATI. I'm not sure what tool is the equivalant. Weird Europeans.

+1.

Do not use normal tools on it, get another from ATI.

I highly recomend going to RRAGES.com and getting yourself a new screw kit and HK push pins. I just got my Gen 2 last week and replaced all the screws with some blue loctite. This thing ran 500 rounds like a champ using a mix of Federal Bulk, Winchester HV, and CCI Minimag.

I ordered the screw set already, but I'd like to keep the original screws as well...just in case I needed to service the rifle.

I figured out what the screw bit type to get. The screw type is called "Pozidriv". The GSG-5 screws requires Pozi PZ1. I went by Home Depot and bought myself a rachet screw driver set that contains a few Pozidriv bits. $4.70 for 38 bit set(which also included the allan bits that fit the aftermarket screw set)...a lot better then the screw bit set the rifle comes with.

Congratulations on not giving into using another bit instead of the correct one.

Now go buy a replacement screw set site sponsor RRAGES.com. They are easy to install and and much more robust than the screws delivered with the GSG-5.

Thanks! Hopefully this will help others as well. Never seen these types of screws before in my entire life.

As you found out, the GSG-5 comes with Pozidriv fasteners.

Pozidriv looks like Phillips, but has eight points like this:

Here are the two bits side by side:

Phillips is on the left and Pozidriv is on the right.

You can use a Phillips bit on a Pozidriv fastener, but you shouldn't unless you just absolutely have to for whatever reason. The Phillips is slightly more pointed and the driving portions of the bit won't engage the fastener and will always want to cam out. You'll very likely to mangle the fasteners this way. If you want turning power without the bit always wanting to cam out under load, use a Pozidriv bit on a Pozidriv fastener. If you are forced for whatever reason to use a Phillips bit on a Pozidriv fastener, press down on the driver very hard to prevent the Phillips bit from camming out of the fastener so easily.

Incidentally, I strongly prefer the bits with the ribbing like the ones above and shown here:

These ribs are sold under a variety of different names by different tool manufacturers. For example, Snap-on calls them "ACR" (Anti Camout Ribs). The ribs really grab the fastener and give you much more turning power than you would get with non-ribbed bits.

These bits are cheap. Even the Snap-on ACR bits cost only a few bucks, so there's no reason not to get them.

Congratulations on your GSG-5. You'll love it.

I was going to post that these bits must not be that uncommon, because after stripping a head out of one of the screws, I went looking for tools and found I had much better (smaller) screwdrivers than the POS the gun came with that were actually ACR bits. If I would have been using these I doubt I would have stripped the head.

Anyone know where I can buy a replacement screw for the charging handle? I had to remove it to install the nylon insert but the head stripped out super easy.

Why do you need to change out the screws?
