I just purchased a drill bit from HB Industries for drilling out the weld on the CZ Scorpion "world legal" model. When I receive this, I will drill my trigger pack weld out, and then mail the bit out at my expense to another forum member. All I ask, is that you use it in a timely manner (no; oh I've been busy, I'll get around to it), and then mail it out at your expense to another forum member. This will help those of us wanting to change out trigger parts without waiting for the trigger pack swap. Please post up in this thread "I could use this #1 , #2 and so forth), and we'll get this sent on down the line.
Here's a link to the bit ill be using and sending out to whoever post the "I could use this #1". https://hbindustries.net/store/shop/carbide-drill-for-scorpion-trigger-pack/ |

I could use this #1.
As a prelim. I'm getting my Scorpion tomorrow afternoon and assume it has a welded pack. If not, i'll edit my post to remove myself from the list. Great idea, OP. |

View Quote Sounds good! It will have the welded trigger pack. I should be getting the bit tomorrow and am going to drill out my weld and will then get it out in the mail immediately to you. Please IM me your mailing address. |

When did CZ start shipping the "world models."
Do we have a serial number range? Did they start with the 2016 model (I have a 2015)? "I could (possibly) use this #3" but I'm deployed and won't need it (if I need it) util August. |

I removed mine several weeks ago at the office I have all the right tools doing what I do.

Please just post the instructions and bit size. View Quote I haven't done it yet, but there isn't much to it. Take out the trigger pack. Drill through the weld on top of the screw & collar. I'd put duck tape on the sides of the drill bit to prevent accidentally scratching the hammer which is in close proximity. Once you are through, you can remove the screw and discard the collar (it is only there so the screw can be welded to it). Either clean up the screw, or replace with a new one from CZ ($4 on there website) or the local hardware store. |

I could use this # 2 or 3. Can't quite till how the list is being counted. Thanks for doing this.

I had a friend bring his CZ Evo in this weekend and I was unaware of the welded screw...and neither was he. After a very frustrating night I finally decided to stop before I lost my mind. I have the proper bit...how far down do you drill to remove the weld from the screw/collar combination? Also, since I have a mill, could I just mill the screw/collar combination down to almost the floor of the trigger pack and then simply toss the collar and replace the screw?
Thanks! The Olde Tom who is pulling his hair out |

Glad to help! Sweet! Yeah, super easy, and I love the HB Industries reduced trigger spring. Now if they would just get their flat triggers and extended charging handles back in stock. |

The Olde Tom who is pulling his hair out View Quote Yes you toss the screw and collar after you remove it. My old screw would not work again but the HB drill kit came with a screw to replace the old one that was drilled. I had to drill mine about 1/8" or more to break the collar. You can tell you are close when you start seeing cracks in the collar and screw hole as you drill. Push the screw out from the drilled side and it will pop out. |

#8 I was waiting till my gun showed up from PSA. Now that I have it in hand would love to fix this little modification!
Thanks! |

I was debating drilling the collar vs waiting for the trigger pack exchange from CZ, when I read on another forum where someone just unscrewed his with a little pressure and the weld broke free. The weld on mine looked pretty weak compared to pics of others I'd seen online. I figured I'd give it a shot and see what happens. The screw and collar made about 2 rotations until the collar bottomed out on the trigger cage. I gave it a little more umph with just one thumb worth of pressure and the screw started turning again and the collar popped off. I guess some aren't welded as well as others. Just figured I'd throw it out there in case anyone wanted to give it a try and hadn't checked yet.

Damn, I just bought a CZ this week online. I bet it has this issue too.

Got it last night Two minutes with a drill and no more spot weld. Super easy to use.
Thanks for sharing! IM sent to rclimber98 |
|
Has anyone tried a regular drill bit? What size do you guys think I should use?
|
|
|
2nd IM sent to rclimber98. If I don't hear back from him by tomorrow night, I'll get in touch with the next person in line.
package off to rclimber98 |

Bit arrived today - thanks! It took almost 8 seconds to remove the weld. PM sent to next shipper.

In for #14. Thank you!
Grew too impatient. Wanted to get the HBI springs in and polish some of the contact points up. If not in a big hurry, I would recommend waiting on the bit. Thank you for offering the bit to other users! That is awesome! |

#15 please and thank you.
![]() So this is totally in lieu of the trigger pack swap from CZ right? |

No need to wait on a trigger pack swap after this, as they'd only be swapping out your trigger pack with welded screw for a trigger pack without a welded screw. It's super EASY and FAST to remedy with the drill bit! I'm loving my Scorpion with the HBI reduced weight trigger spring and Theta trigger. |
|
Guessing you need a new screw for the trigger pack after the drill job?

#16 - Pay it forward -
Just found out today about the welded mess. Does anyone know what other changes (besides the welded screw and collar) were made in the World models ? |
|
I also have a drill bit from HB Industries for the CZ that I can send out to someone? Who's next, I think two of these going around would be super helpful!
