Marauder rifle trigger group on a 13xx action

[bantam5s]

I was under the impression that they could pretty much drop right on, sometimes needing some sort of shim or something.

I ordered one that arrived today and it is really not even close to being compatible.
The screw holes are positioned completely different , and the sear seems too far forward or something.


Can anyone tell me what version of marauder trigger group I need to be looking for ?

Is the factory discovery trigger group metal, or the same plastic one as the 2260 ?

[Tack Driver 10]

I put an MRod trigger on a 140 a few years back.
Not a drop in but not too difficult, had to make some custom parts.
The MRod trigger on a 13xx should be a similar build as the spacing is the same.

Replaced the blow off valve with a hammer valve, steel breech, etc
Used to be on the Yellow but it's gone now.

disco trigger is the 2260 trigger.. and the mrod trigger has little in common

This is one I have on a 2260 tube.  It required a shim and elongation of the slot on the tube.  Also the oem trigger has been replaced with a theoben.  This is the first one made, I think the current production is different.

Yes I know.
Just wondering if the disco trigger group was the same plastic one or metal because I know they'll fit but don't want plastic.

I don't want to spend $150 plus on a custom disco trigger group but will of it's really my only option.

[Rob M]

David , yes same plastic.. Id try to do the mrod trigger before spending the 150 on whats basically a cool disco trigger housing.

I'm not building something super fancy and custom looking here, so I'm not looking for a target trigger or anything I just want a complete trigger unit that isn't plastic.

The whole housing doesn't match up on the marauder unit I bought, and I don't think it can be made to work.
If I can figure out which version of marauder trigger unit / house ( the entire thing not just the internal parts)  I can try to get ahold of one, but I need to get this figured out first.

If yours uses the same trigger group as a Disco, the Mrod 2/Challenger trigger will WORK. l have one on my Fortitude. You may need to do a little tweaking as 7624552 suggested and the trigger slot in the stock will need extended, but it is a great improvement.

I have an aluminum disco/2260 trigger housing from magnum air power it is the only metal one I could find. These pictures are from the web site and are out of stock right now.

To be clear here when I say trigger group I'm talking about the complete unit housiand all
The housing on what I received today is physically too short to mount on a 13xx tube, it is does not extend to the screw hole in the tube.
It's the gen2 so I assume what I need is the gen1, but I want to make sure there are no other variants before I track one down.

What I have is a complete marauder trigger unit and housing...ect that I ordered.

The Challenger group is the same as a Gen 1, I mis-spoke before. Gen 1/Challenger is it. 1763A105 is the part number. The spacer is not necessary. If the sear drags on the hammer after assembly, you can cut one out of a plastic bottle. It needs to be about .030" thick.
You may also want the guard and screw. here is the EVP.

I can't find the complete unit in stock online,  so I'm wondering If Crosman even still has it.

If I can get the housing, how many parts from the gen2 unit can I actually use ?
From what I understand you have to order every individual part when going through Crosman, I'm not looking to do that because  I don't want a repeat of last time where I was having trouble with none of my part numbers being correct.

[Rick67]

$rcher $irguns sells Gen2 MROD/Challenger trigger assemblies.

[bantam5s]

$rcher $irguns sells Gen2 MROD/Challenger trigger assemblies.

That's where I bought mine, I need the gen1 apparently.

[Rick67]

AFAIK, they are no longer available even from Crosman.

The part number I gave you is the complete assembly for a Challenger.

Okay,  thanks.
Have you ordered one recently?
I made an order Monday armed with outdated part numbers from an old diagram, and I just wanna make sure I've got a correct part numbers for this particular order.
I don't want to become " this guy again " who always calls them up with bad part numbers.

[mobilehomer]

It has been a while since I ordered, but I copied the P/N straight from the Challenger EVP.

I just checked the current EVP and the number is correct.

The gen 2 Mrod trigger will fit the 13xx tube.

It's covered here, remember?
