This will be my second write up on the Nerf Rampage. In the first post we went through a basic air restrictor removal. That was a nice start to an already decent blaster but Black Tactical is now stocking replacement springs for the Rampage/Retaliator and wow but are they fun. I’m quite a fan of this rampage at the moment but friends who I’ve done the same swap for have complained that it’s too hard to prime. Not for the feint of heart or arm then!
I had just picked up a brand new Rampage for the purposes of this mod so we’ll be running through the AR removal again. Because the BT spring is shorter than the stock spring, we also need to remove.bypass most of the stock locks.
BT Elite Spring
Coat hanger or some other wire to use for pinning
Drill + extra long drill bit
Round hand file
See, told you it was a brand new blaster. Haven’t even put the clip well in yet…
Remove the end cap. It’s held on by two screws that are different to every other screw in the blaster; remember this for reassembly.
Then remove the five screws holding the priming handle on.
Then the rest of the screws holding the shell together. As always, take a moment to have a good look around the internals and try to get an understanding of how it all works.
Cool. Now remove the main spring.
Then the catch.
Then we can lift the whole breech/plunger assembly out of the shell.
Separate the breech form the plunger.
Using a small screwdriver, push the pin that holds the breech together through so that it pokes out one side.
Then pull it the whole way out using a pair of pliers to separate the breech from the priming sled.
Looking down the breech we’ll find an AR.
Take to it with a drill, then clean up by hand with a file.
Then we can reassemble the breech.
Cool, AR removal done, lets remove some of the locks.
First up we need to remove this orange cover piece.
If we flip it over, we’ll find two small clips. Pry these in with a flat head screwdriver
Once that’s off we’ll find these locks.
Remove both of them.
We’re now looking at the underside of the trigger bar. The orange piece here normally slides back and forth with the plunger tube but with the shorter spring, we don’t want that to happen so we’re going to pin it in place.
Start by sliding the trigger bar as far back as you can then drill a small hole (the same diameter as your wire) through both the white mounting piece and the orange bar itself.
Cut a small piece of wire and bend it into a right angle.
Test fit it through the bar. We need the top end of the pin to clear the top edge of the white housing, but only just. There *shouldn’t* be anything for it to interfere with as far as I can work out, but keep it neat anyway and remove any chance by having it extend <1mm past the top edge. If it’s not the right length, trim it!
Once we’re happy with the position we can glue the pin in place. Place a small blob of glue other the hole, then insert the pin, then run some glue around the outside.
The last lock we need to remove is actually on the other side of the shell. Remove the orange piece just below the clip well, held in here by one screw. Interestingly, this is a US spec orange trigger Rampage but in the Aus spec grey trigger model, this part is actually white. Odd hey?
Here we can pretty plainly see the difference between the BT spring on the left and the stock spring on the right. The BT spring is significantly stronger but we did have to remove all those locks because of the length.
And on that note, I’m going to call it for this post since I apparently forgot to take reassembly photos… I still believe in you though; reassembly is simply the opposite of the disassembly we did earlier, just don’t put the locks back in.
