#344698 Nerf Doubledown

Posted by racer188 on 30 January 2015 - 09:32 PM

Just got the Doubledown to add to my mod list. The bin of "to dos" are getting rather big now. Hopefully I can get to this soon. It does look like a Smart AR so not sure how much performance gain is possible. Although the plunger tube and spring are super long the draw is actually only to the front of the trigger.

Anyhow here are the pics.

Upcoming blaster, looks to be a single fire version of the doubledown?

Hopefully I can get around to this one. I still have my sharpfire awaiting a new breech system.

#344333 Bigshock Mod 110fps avg

Posted by racer188 on 16 January 2015 - 10:35 PM

Hey everyone FNG here. Just wanted to share one of my latest mods, Nerf Bigshock. Modded to fire elite and stefan sized darts.

So instead of simply removing the dart post and the AR I took it a step further and boiled out the end cap giving me full access to the entire barrel. I removed the post then dremeled down the remaining material and smoothed out the edges allowing for smooth air flow.

While I was examining the gun I realized by removing the AR there is dead space now in the rear of the gun where the cap was. What I ended up doing was molding a cap, using hot glue, cpvc and Vaseline to essential plug the rear dead space and channel the air directly into the new 1/2" barrel.

I was also able to remove the permanent pin holding the plunger head in place giving me access to play with different spring combos.

Off the chrony this is what I got when testing with a 1/2" barrel:

Stock Spring: 70fps (before pluggin the deadspace)
7Kg OMW Roughcut Spring: 95fps
7kg OMW nested with Stock Triad Spring: 110fps
11+kg McMaster Spring: 130fps

This blaster has some real potential. I was surprise dot see number like this off a Jolt style blaster. The 11kg spring is really hard to prime so I opted to use the 7kg + Stock Triad. This blaster can leave some nice welts with hot glue tip stefans or Chinese solid tip darts.

Hopefully I haven't confused everyone with what I was trying to explain with the dead space removal. I have plenty of more projects to share. This is just a first.
