I came up with a simple fix for that problem. This modification requires no sawing, dremeling, or any other destructive tools besides your needle-nosed pliers.
-Two 6'' segments of the barrel material of your choice (I chose brass)
-Hot glue gun
Remove the barrel posts in the stock barrels by twisting them out. It is important that you twist them because if you attempt to dremel them out, you risk destroying the entire barrel assembly.
Open up your Splitfire and remove the trigger spring. Place this spring somewhere safe and remember where it goes. After you do that, take out the rest of the gun and pull out the pump. See that hole on the back of the pump? That's bad. Fix that up with some hot glue.
Then put a tiny dab of your silicone grease on the o-ring to keep it happy.
Plug any and all holes that you find on the stock barrels with your duct tape and hot glue.
Take your barrel material of choice and wrap electrical tape around it until it fits very tight into your stock barrel.
If it doesn't fit right away, don't force it. Just simply cut off some E-tape until it fits:
Keep in mind that it needs to be as tight as possible without forcing it in.
Shove the barrel down into the stock barrel so that the end of the barrel material is resting on the yellow circle that used to attach to the AR peg:
Hot glue completely around the new barrels to keep them stable and durable.
One cool part of this modification is that if you ever need to switch barrel materials or need to straighten your barrels, the hot glue is completely removable and you can pull the barrel back out.
You're done! Now go blast someone!
Ranges with 6 1/2 pumps:
With 2 stefans: 51' flat , 61' angled
With 4 stefans: 41' flat , 50' angled
With 6 stefans: 32' flat.
Ranges with 10 pumps:
With 2 stefans: 69' flat, 79' angled
This isn't bad for a secondary gun. Even though the ranges are lower, the modification has the advantage of not being permanent and not destroying your gun. It is a very satisfying weapon to use, especially when you shotgun load it with 4-6 stefans.
