Well Yesterday I got my second Raider after seeing this
Posted Image
I kept my first one stock out of fear of breaking the plunger tube like 2 of my recons prior.

Major things you need

Longshot scope
Enough brass for an angel breech
At3k or similar (just pump and tank)
tubing coupler
RFDG spring (doomsayer)
Various modding materials and tools
-------------------------------------------------------------------------------------------------------------------------------------------
Part 1 Brass breech

If you just took yours out of the box do this now if not do it when you open it.
Posted Image
Take the drum rest and open up those 2 screws.
Posted Image
Take out the orange piece there and put that back together. This lets you activate the clip lock while the breech is closed.

Open it up nothing tricky
Posted Image

Throw out the white piece and the dart tooth. Unscrew the 4 silver screws and take out everything else. Set them aside.

Posted Image
Get your brass out but the correct sizes not the ones shown
9/16
1/2
19/32
17/32

Take your 9/16 and cut it to 7.5 in, and make a 3 1/4 half pipe, and add tightening rings
Posted Image

Make a 1/2in long section of 9/16 and 17/32, glue them together.
Posted Image
Make a 4in length of 19/32 and flare out one end with pliers
Posted Image
Make a 4in length of 1/2in.
Assemble the pieces like you would an angel breech

Take the piece that the dart tooth goes into and sand down a ridge where my finger is.
Posted Image
Take your barrel and wrap it in e-tape until it is snug in the piece from above and glue it in,
but make sure the breech cover can still go over it fully.
Posted Image

Now chop off the back of the stock breech tube so your brass can fit in it like this.
Posted ImagePosted Image
Make sure it is the complete assembly is 7 inches long.
To kill some dead space take some 15/32 brass, wrapped in e-tape, and shove it in the back until it rests on the breech cover.
Posted Image

Make the connection from the stock barrel to the breech cover like an angel breech; there is no exact measurements just make sure it all fits and closes fully.
Posted Image

Posted Image
Open that up and fill it with hotglue and put it back together.

Put some padding on the plunger and boltsled.
Posted Image

If you don't have a RFDG spring put a 1/2in segment of 3/4 thin wall pvc on the plunger tube.
Posted Image

-----------------------------------------------------------------------------------------------------------------------------------------
Part 2 Integration.

Put you air tank in the scope and have a trigger too.(isn't it always funny the one picture that gets lost is the one hardest to get again)

Cut your stock like so
Posted Image
and the gray piece
Posted Image
you'll have to sand it down to fit a 3k pump in.
Cut the pump shaft down and put some 1/2in pvc over it. Glue it down
Posted Image

Put bars on the pump tube so it can't fall out.
Posted Image

Close up the stock and connect the tubing and your done.

OR...
Cut the shell,
Posted Image
glue your pump in,
Posted Image
Cut off the auto-rotation tab from the pump,
Posted Image
Drill and tap a hole in the handle I used 6-32 and a 1 1/4 screw.
Posted Image
------------------------------------------------------------------------------------------------------------------------------------------
Part 3 Grip mod

I did this because I didn't like the handle.

Cut the stock handle like so.
Posted Image
Then cut some pvc like this
Posted Image
super glue/hotglue/epoxy putty them together.
Posted Image

Part 4 Pictures and ranges.

Posted Image
Posted Image
Posted Image
Posted Image
Posted Image
For the raider it is 60-70, it does better with lighter darts i.e. single bb.
The At3k gets 80-90, but its unplugged and I f****ed up the pump, so I need a new one.
I replaced the pump with a sm3k and it isn't messed up and the ranges went up.

If your wondering why the breech opens so much it's because I originally planned to use streamlines with this, but angel breeches hate stock darts with a passion.

Very nice. Finally someone writes-up on who to convert Angel Breechs for reverse plungered guns. Everything looks extremely well done. I applaud you sir. You are one very productive member.

So it's a 1-pump 3k?

....Nice.

Overall, great writeup. The only problem in my opinion is that if you want to go all out with darts on someone, then it gets very difficult to do so because of the pressure of the AT3K pump/tank setup. In addition, you could create a leak by pumping it (the raider) too many times and not firing the AT3K tank. But like I said before, overall, it looks great.

That's a pretty good deal on the raider, and nice mod. The only thing I'm missing to do this is the brass and LS scope.

Zorn's Lemma- It takes about 2 pumps to fully prime the 3k

cheesypiza001-That's super glue and brass cuts on my fingers I received to give this gun to everyone. If I use a six shot stefan clip I can use the 3k as a hold out while I'm reloading, and If I don't shoot it then I'll just take a pot shot.

Pump in the stock: LOVE it! I thought about jamming a pump in an LS stock but the logistics were poop, but you made this look like a no-brainer.

*switches on ass-crown machine*

Nice work, I formally convey my acknowledgment of your contribution.

So the 3k can't be used while you still have darts in the mag because you'll be shotgun loading.

I can use the 3k every 2 shots, since it takes 2 pumps to prime it.

Very nice, the integration is pretty clean, despite logistics of priming and pumping.

Would you say the brass breach significantly added range, then?
It seemed like the last brass'd one did not, but these ranges loot a lot better. I'm considering getting a raider then (especially if it comes with a second clip, even though none of my other guns take it...), and I feel if you can squeeze 60-70' out of it, without springs in the stock, it could be a decent primary, with the ROF.

I would say that the breech was too much work to go through. It adds a little range compared to a fully modded one with a stock breech yet it drastically reduces ROF, since it takes away the drum magazine, and slam fire.

If I was to do it again I probably would invest a lot of time into making the stock breech as near perfect as can be, instead of making the brass breech because right now this is essentially a weak Angel Breeched Longshot.

I tried putting some springs in the stock but even with some beasty catch springs it just won't work, but if you used the stock spring you'll probably be able to add some springs in the back.

Nice, but nothing you can say will convince me that that raider is hitting 60 to 70 feet consistently without an angle, wind, hill etc. I was actually going to at some point integrate a pump into my stock when I realized how easy it was to hold down the release and slide it back and forth (if you sig this please don't make a whole post about it). I was gonna use a BS tank or something to replace the stock air deliver system. Nice execution on that bit of it.

Good work! Did you leave the OPRV unplugged because it would come in handy now as you wouldn't need to take a shot every 2 times you fire the raider.

I'm not sure if someone has already said this because I didn't read every post, but it would be a GREAT idea to cut off the stock pump thing in the front, and hotglue/epoxy on a modded nitefinder. Kinda like the nitefinder integratsions for the BBB. That way it would be 3 guns. A fast firing raider, a long distance 2k/3k, and a sidearm all in one!

First off, I'd like to say....SCORE! I got mentioned!.....OK, now that that's out of the way, nice mod. I did a similar breech on my raider, and it works just fine with streamlines, without reduced ROF and its drum mag capable. As soon as I get a working camera, I'll put up some pics and a video so maybe some fine tuning can be done. Also, interesting 2K addition, but I like not having external tubing. Nothing personal against your mod, its just a preference. For a backup, I simply bolted an Eliminator in place of the priming fore-grip. I still get a vertical fore-grip, along with a backup shot!
