The cool thing about this gun is how it functions. Razor Fin holds 2 darts. Cock the gun and squeeze the handle to fire one dart. Cock the gun again and it switches the barrel thats being fired to fire the second one. This modification was originally going to be an easy barrel replacement but it didn't work and I didn't feel I need to waste the patience to figure out why on this gun. It was at this point I decided to minimize it.
The bad thing about this gun is its hard to aim and pull the trigger because it has this garden hose sprayer feel. This is one of the main reasons people stay away from this gun. The other reason is the fact that its plunger tube is vertical which means there is upward recoil. Enough talk, down to business.
Now open up your Razor fin and take out the plunger tube assembly and everything else and minimize this sucker. Cut along the red line with a dremel.
Now cut out this section at the bottom of the handle. This will be making room for the new trigger.
The end result should look like this.
Now take your plunger tube and cut the hoses that originally connected to the barrels.
Now take your pipe cutters or hack saw and cut in the plunger tube right before the weird spiked round white piece.
Now wipe down and sand out the first little bit of the plunger tube. Now take 3.5"-4" of PVC and wrap some E-tape around the base of the pvc. Wrap enough so it will sit very snug inside the new plunger tube.
Then Bust out the plumbers goop and apply plumbers goop to the base of the PVC and jam it in the plunger tube. Let it sit dry for 24-48 hours. After the Goop dries take some Petg/brass and wrap E-tape around the ends and put some Goop on the E-tape and middle and slide it into the PVC. To help prevent a dart getting sucked into the plunger chamber I added a small piece of copper wire to the base of the petg and Glued it in place.
Now lets move onto the actual plunger bit. Common mods are done here. Spring replacement, E-tape around plunger head, added lubricant.
The catch spring on the Razor Fin is actually pretty strong and does not necessarily need to be replaced.
Now for the part thats unique about this mod. The Trigger!
I knew this had to be changed so this is what I came up with. Do you remember when we cut that gap at the base of the handle? This is the space where the catch actually lifts up. What I did was cut down a sheet of plastic and then drill a wide hole through the plastic so it would sit perfectly on top of the catch. Super glue and plumbers goop holds it in place. Here are a few pictures.
When you cock the gun the plastic plate/shell rises. When compressed the Razor Fin fires.
The gun is now held kind of like how you hold a spear before your throw it.
The finished product.
This thing could get a real nice paint job but I have so many bigger things on the go right now in the Nerf Workshop.
It gets a comfort rating of about 6/10 but it is still fun to use.
It makes for a nice little sidearm.
Ranges are probably around 50-55 feet. Ranges are guessed. It is Winter and I live in Canada remember!
