Hey guys I have a gen i trigger group for my Maximus. While the trigger group works out perfectly, I can't figure out what screw I need to attach the Challenger style trigger guard. the trigger guard has the hole that lines up with the hole in the trigger group but there are no threads in the hole of the trigger group .I'm using the disco wood stock as well.
Did you guys use some self tapping screw into the trigger group? I don't have tap an dies to make threads. I thought this mod , especially in the wood disco stock was just drop in. It is with the exception of how the trigger guard attaches. Help anyone? Hope I'm not missing something right in front of my face with this .

Hi....
I have the same setup with the Maximus. I think you just need a wood screw to hold it in. I don't think i tapped it.
I noticed my trigger sits a little high, but still works great.
How does yours fit?

For whatever reason, the Gen1 / Challenger trigger assembly does not have the hole tapped ??? . I installed a Challenger trigger guard on mine after tapping the hole. IIRC, I enlarged the hole very slightly for the largest metric machine screw that would go through the trigger guard, but any machine screw could be used.

Thanks Craig , since posting this morning i used a self tapping screw then backed it out and filed down the length as to not hit the tube. Worked out fine. I had no clue what I should have done but it worked .

Good to know at least one difference between a Challenger PCP trigger and an M-Rod (gen I) trigger.

But, they are the same part number: 1763A105

Only have a Challenger using that trigger, so haven't had an M-Rod to compare it to. At least on mine, the metal guard is secured with a threaded screw.

Definitely weird that they would tap the challenger trigger group and not the MROD wwhen they are the same trigger group.Lol, go figure.

Looking at one of the older Challenger schematics, they use to use a different trigger assy. Given the "1763" in the part number, usually means it was introduced in that model, in this case, Gen 1 Mrod. So it was probably migrated over to the 2009 Challenger.
When I have used it on long tube prod projects, I have drilled and tapped a hole for that screw to have three attachment points, like how it is mounted on Mrod. You do need to "machine" some off the valve for clearance. Just threading the trigger assy hole or using a short self tapper, is much easier.

yeah i used a slef tapping and then filed the point down short.

Never really had a reason to check what the Challenger trigger guard screw actually threaded into until this post...took it off and checked.
It's a long screw that passes through the untapped hole of the trigger unit, passes though an untapped hole in the air tube,and threads into the part they call the "transfer bar assembly".

Duh moment....to get to the above stage of take down,had removed the trigger unit (including the guard)and just didn't really care what the guard screw threaded into...now I know.
No MRod at hand....but it seems there is one trigger unit...that has an extra hole that is useful for the Challenger...but not immediately useful for a Disco/Maxie as they don't have that "extra" part for it to thread into.
(Buy the way...coming from N-Alabama dirt farmer and Appalachian Hillbilly stock...I recognize a "work around" when I see one. That transfer bar assembly is one.)

Great investigation - not having MRod or Challenger, I thought Crosman simply did not thread the assembly delivered as a part. (Which I then threaded)

Thx for solving the mystery. :)

Now I get it. No hole in the tube of the Maximus to thread into. Well at least it could still be used once you tap it.
