What you'll need:
1x Nerf Maverick
1x Needlenose Pliers
1x 19mm felt pad
Silicone-based lubricant (check and make sure that it's safe for both metal and plastic)
Step 1: Removing the Slide
2. There are eight screws, all the same length, on the outside of the Maverick. Remove them all and set them to the side.
1. Once all of the screws are removed from the outside of the gun, pry apart the two halves. If they refuse to separate, carefully pry them apart with a knife or another thin tool.
2. Now that the inner workings of the gun are revealed, carefully remove the large spring and set it aside. Then, remove the barrel assembly from the rest of the gun. This is a little easier if you press the magazine release button while doing it.
3. Pry the front hinge off of the barrel (Pic 2) using a screwdriver or similar item. This might take a while. Once it is removed, let the metal axle piece fall from the barrel assembly. (Pic 3) There's a small spring on the back of the axle. Make sure you don't lose it!
4. There are three screws on the back of the barrel assembly (Pic 4). Remove all of them and set them aside.
5. Remove the back of the barrel assembly (Pic 5).
6. Remove the orange caps from each barrel (Pic 6). Below each one should be a small spring, and a smaller three-pronged piece. These are the air restrictors. Remove them, then replace the orange caps. Once you've done so, reassemble the barrel. Be sure to put the screws back in!
On the front of the front hinge piece is a small rectangular protrusion. This is the first half of the magazine lock. Cut it off. Once you're finished, make sure the surface is fairly smooth. (Pic 2). Once you're finished, reassemble the barrel assembly. If you're confused about how to do so, refer to step 2.
The second magazine lock is located on the left side of the gun (Pic 3). It's a part of the frame, so just carve it down until it's no longer there. (Pic 4)
Step 4: Increasing Spring Power, Reassembly
Now, remember those two pennies and that felt pad? Grab 'em. Stick one of the pennies to the felt pad, and put the pennies (felt towards the back) in the back of the gun, where the spring used to reside.
Now, cut/shave down the cross on the back of the plunger assembly. It doesn't have to be neat, it just needs to be cut down, and the top of the cross should be even. (Pic 2)
Once that's complete, put the plunger assembly and spring back into the gun. (Pic 3)
Step 5: Finishing the Reassembly
Once you're sure the internals are in order (see Pic 1), put the two halves of the Maverick together, then replace the screws.
Finally, assemble the slide. Remember to hook the spring (noted in Pic 1) back onto the slide.
