I just got the Nerf Firefly and I must say that it is quite a nice blaster, but I still wanted more. I opened it up, took out the air restrictors and pegs, and did the removable turret mod. Now that it is reassembled, it only shoots when fired straight up. I cut off the pegs and added the bases in but it didn't help much. Also I don't have the outer casing of the turret, as that also made no difference. Sometimes it will shoot but usually not. Every time when it is pointed up it shoots perfectly.

Here is a youtube video of the problem:http://www.youtube.com/watch?v=M8CdLeIoVZI

As you can see from the video sometimes it shoots and sometimes not. Any help?
