I've been around here for a whole, however didn't really want to post without anything decent to contribute. I'd like to thank the while community for all the great content, almost everything I've learned about nerf has been through a combination of this site, some research and good old fashioned trial and error.
Special props go to popatachi who did something similar earlier, though I did not consult his mod for this it certainly paved the way.
Raiders suck balls. Period.
I wanted to make one that didn't. Actually I wanted a clip fed gun with 4B kind of power, and the raider shell turned out to be way too perfect. It is a comfortable and cool looking shell, especially with the fron handle removed. Given that they both have the same breech this could be adapted to a recon etc
AFTER I'd done this mod a friend went "oh coop made a clipped big blast", which you can get the same functionality out of, however I like this shell so so so much more than the 4b, the pump faces fowards and is more efficient and it actually holds clips and drums well and uses the stock clip lock for additional stability.
Things I achieved
- consistent, reliable feeding from n strike clips
- greater than 100 ft range
- uses stock clip receiver
- No glue holding anything structural - all hardware
- Comfort and accuracy
So here we go. I sometimes forgot to take photos until after I had completed a stage so the pictures are not completely step by step, I apologize.
Step 1 - Open up your raider and your mega missile. Having a 2nd gen mega missle is key as the tank is not welded to the pump, but rather connected with tube.
Disconnect the tube but keep the white lock nut, and gut the raider internals save the jam door. Keep the trigger and the brackets that hold in the boltsled. Anything else is useless.
place the tank in the raider, so the right angle connector extending from the tank is sitting just in front of a piece of shell that sticks up near the trigger.
Mark where the large centre band of the MM tank is on the 2 internal walls of the raider shell and cut a channel so the tank can sit within the walls. This is all you need to do to fit the tank.. freaky right? it's like too easy...
As you can see in the pics I have cut my mega missle barrel (the orange bit) off about 3-4mm above the black part of the tank. do this now if you haven't already.
Cut a 20mm conduit couple at the 3/4 mark. it should now fit onto the front of the tank with some 'persuasion'
Now I put a piece of 20mm UPVC in the coupler and put the tank inside and closed the shell. Using a fine tipped sharpie I marked where the clip would go when placed in the stock clip receiver.
Then I took it all apart, clipped on a nstrike clip within the lines I had drawn and traced around the top of the clip.
Cut it all out and it will look like this
Now to make a slide breech work correctly with clips there must be a 'nub' that the dart gets pushed back against to force it into the breech. Making this 'nub' in the limited space was challenging and this is what I came up with. most importantly it has to get fixed to the tank but not interfere with the x shaped guide which ensures the valve makes it back to correct postion after each firing. There is very little room to play with behind the breech before the tank, so it cannot be attached to the walls of the barrel or you will sacrifice some of the precious little sealing surface.
So what I came up with.. cut (roughly) 2cm of 1/2" brass and 17/32 brass. glue the 1/2 inside the 17/32 halfway down. Sand/lathe a piece of 12mm OD ALU tube until it fits inside the 17/32. glue it all together and then inside the orange stub sticking out the tank, being careful with your glue so you dont glue the tank shut. pics will help this make sense
I used a 19/32 and 9/16th sliding breech - the part cut to match the conduit is the 19/32 while a whole piece of 9/16th slides back and forth.
Picture limit reached. do not post.
