Not Another Marauder Bullpup Question....Marauder to Bulldogish Conversion

[ShadowShot]

Most of the Airbow parts are the same.  It may save some extra cutting.

Did anyone find the video where he opens it up?   I'd like to see what he did for the trigger lever.  On the BD, when you pull the trigger, the rod moves forward, not backward. 

When I suggested looking into an existing BP to get parts, didn't think the BD would have been a good candidate.      He made it work. 

Many of us here, thought Crosman should release a BD in smaller calibers, such as 30 and 257. 

[ShadowShot]

Apparently he hasn't made it yet. YEMX and myself both commented on his channel and asked him for a follow up. No response yet. I think of he gets a few more request......

Yes, Crosman should but who knows why they don't.

I just downloaded the bulldog parts list. Looking at it closely, it looks like the linkage pushes backwards. I could be seeing things wrong.

Look at the trigger closely and you will see a pivot pin.  When the trigger is pulled, the top part of the blade where the rod is attached, moves forward. 

It was one of those things I noticed when I had my BD apart for the first time. 

I suspect he has some type of lever to reverse the direction, but how attached to the trigger blade, etc.  All the little details he can help you with and don't have to learn/overcome, the better.

Very useful to know. Thank you.

Bulldog parts prices for the stock are:

LH and RH shells: $10.50 ea.
Top Rail (none in stock currently): $31

I didn't get prices for anything else, but it looks like for a DIY jobber, only a few trigger components may be needed- front and rear clevises, the trigger rod.  Everything else would have to be fabbed up.

I was thinking if you could find a breech riser/long extender, that would be better than using the BD shroud.   I've seen them on other Bullpups.   Not knowing how the Mrod action is tied to the BD shroud, concerns me for poa/poi changes.

This is not what I pictured in my head, but similar concept:

I've actually used this extended on another rifle. They do well.
The way the mrd fits into the BD housing has me concerned also. It's going to be like any project, trial and error.

[ShadowShot]

Ok, I've studied this thing over very closely. I don't think I will do everything like James did on his on his youtube Video. I have some ideas of my own already.

 I downloaded the manual for the Bulldog, BPBD3S EVP.PDF. I went through it very closely and ordered everything it looks like I would need. Everything was in stock and should  be here in about one to two weeks. Total price for all the parts........$169.35 shipped. Now all I have to do is await the parts and then the project will begin. Wish me luck. I'm going to bulldog my Gen1 .25 Marauder.

Here is what He did.

Skip to around 8:25 if you don't want to hear a long backstory.
I have started looking into it. Parts are very cheap.

Do we call it the "BullRod"   

[FuzzyGrub]

Please keep us all abreast of your build.

Now that made me laugh right there. Won't be alot to post about until the parts come in.

Bullrob... Hmmmm?  Pitpup...
MarauDog...Who knows.

Good luck with the build Paul, good you found an inexpensive alternative that looks pretty cool. Love that kit of Motörhead’s, looks kinda like a Daystate Pulsar.

[mackeral5]

Good luck with the build. 

I would love to see someone go in the opposite direction and build a small-bore Bulldog.  Once the powerplant was tamed it would make for a bunch of low-mid powered shots. 

Motorhead's B51 is one of the coolest DIY bullpup builds I have ever seen....

Ok, this was a job. I will post later the work I had to do but for now, I have a Marauder Bulldog .257!

 I need to add the flex hose and foster fitting to fill the unit at the front but for now, It's fully functional and working. I buggered up the metal in a couple places, I will either black paint or camo the gun.

Here she is.

[ShadowShot]

Ok, just to clarify, it's only a .25 cal. I guess I could try some slugs in it and call it a .257.

[FuzzyGrub]

Looks like bulldog until you focus on the breech.  Nice work.   

[YEMX]

Very nice indeed!!  I may yet build a .30 Mrod for a fraction of what my last one cost    I'm very keen on seeing how the trigger stuff worked out!

[ShadowShot]

Ok, just a quick post on the trigger system. First I removed the safety, I will use the one on the bulldog.
I had to make an aluminum trigger frame to mount onto the Marauder trigger group. I bought some longer screws to replace the two lower screws I would be removing and replacing when I mounted the new trigger group onto the Marauder trigger. I then cut out an aluminum trigger to size, trimmed it down and polished. I used several washers as spacers on the new trigger.

The bulldog trigger rod was too long. I cut it to size and remilled it with my redneck lath. (a drill in a vice to hold and turn the rod, with a drimmel to size it and sand paper to polish.) I then rethreaded the rod.

After assembly. I adjusted my Marauder trigger where I wanted it and then tied it to the new system. Oh wait, I need a piece to connect the two triggers together. I found a thick aluminum spacer and drilled it to fit over the Marauder trigger and a cross drill for a swivel link. Then I had to make the link, that was easy enough.

By far, the trigger was the hardest part. More to come later.

This is not what I pictured in my head, but similar concept: 

I was trying very hard not to modify the Marauder in any permanent way.  I had a problem with the action shifting back and forwards inside the BD  when cocking the rifle.  I finally had to take two parts on the Marauder and modify them to secure the action. If I ever want to put the rifle back into stock configuration, I will need a new barrel band and the rear pressure tube cap behind the hammer spring guide.

I took the barrel band and pointed it down instead of up.
I had to cut the band that use to go over the barrel in half to fit downward in the stock. The purpose of this was to have a stock and action mount point. Once I found the correct position, I drilled and tapped threads into the barrel band. I then secured the stock to the barrel band with appropriate  screws. I drilled and tapped the hammer spring guide cap and secured the rear of the action to the BD. Everything is now secure, nothing moves. I only have two parts to replace to restore rifle to original condition.
