I do have a Demo review in the works, it'll take a couple days to get all the pictures and type it all up, but in the meantime here's a video of how fast you can empty a Demo.
Time: 1.833
No. darts: 18
ROF: 9.27dps or 556.5dpm
The Demolisher is the only blaster I've used so far that gets a ROF anywhere near that of a Magstrike, which is impressive considering the Demo is semi auto. It beats both the Stryfe and Rayven, though I've yet to test the Rayven with trigger mods for a smoother/easier trigger pull.
Nerf claims the Rapidstrike can empty an 18 clip (mag) in 5.62 seconds. I put that claim to the test in a quick video.
Batteries: 4 x Toys 'R' Us branded C batteries
Time: 4.923
No. darts: 18
ROF: 3.45dps or 207.2dpm
So yes, the Rapidstrike can achieve the claimed ROF. Considering Nerf's recent track record with performance claims, this is a surprise, and a good one at that.
So with the slam fire and rapid fire vids I've been making recently, I thought I'd make an actual YouTube series out of it, called How Fast Can it Be Emptied?
First up of the 'official' HFCBE videos is the Nerf Magstrike AS-10. As the fastest firing production Nerf blaster, I thought it'd be a good blaster to start off with.
Time to empty: 0.68sec
No. darts fired: 10
ROF: 13.2dps or 794.1dpm
To compare, a stock Stampede or Vulcan fires at 3dps, and although I dislike firearm analogies when regarding Nerf, I have to use this. The M16A3 assault rifle according to Battlefield 3 fires at 800rpm.
There is literally no Nerf blaster I've used that is anywhere near comparable to the Magstrike in terms of ROF.
The second of the videos I recorded, I show how fast you can fire a semi auto flywheeler when you really put effort into it.
Time: 2.1sec
No. darts: 18
ROF: 8.10dps or 485.7dpm
For reference a stock Stampede or Vulcan 3dps or 180dpm, and the 16.8v Rapidstrike featured in RandomShadow09's video empties an 18 clip in 2.2 seconds.
Also the EAT slam fire vid features around 7dps or 420dpm.
It's been a while since my last vid, so I thought since I had a bit of spare time I'd shoot some quick vids for you guys.
First up is a slam fire vid of my EAT. Now you may be wondering "It's just an Alpha. What's so special about slam firing it?" Well, this is my modded EAT with the 8.5kg BT spring in it, over 3 times stronger than the stock spring.
Time to empty: 2.58sec
No. darts fired: 18
ROF: 6.59dps or 395.3dpm
For reference, my Pyragon slam fire vid has a ROF of around 6.8dps and a stock Stampede or Vulcan is around 3dps.
Just a note on modding the EAT, I would not recommend removing the AR as with the 8.5kg BT v2 spring it gains hardly any range (with Elites) and of course without the AR there is more internal stress. Average range does get pushed up to the magical 30m (100ft) mark though.
EDIT: Don't pay that range claim too much stock.
Muzzle velocity is increased so if you're a stefan user ranges will be increased more significantly.
It does make an awesome sound so if you're into that sort of thing go ahead, but otherwise I'd leave the AR in there for use with Elites.
I finally completed my AT vs Raider slam-fire off vid after months of procrastination.
The AT's ROF is 6.32dps, while the Raider's is 6.00dps.
I personally far prefer the AT, but some people might prefer the Raider. In any case, the point of this vid was simply to compare slam-fire speeds.
My original Pyragon slam-fire vid you couldn't see the discs flying, and all you could see were disc impacts on the curtain and hear very loud rapid-fire noises. This new vid allows you to see the discs hit the lace in front of my window, and also lets me accurately measure the time between first and last disc impact.
Anyway, the vid:
I empty the 40 disc drum in 5.87 seconds, meaning a ROF of 6.81 discs per second. Note the disc spray, though, and this is at a 1-2m range.
In this video I slam-fire the Pyragon's entire 40 disc drum in 6 seconds.
This means its maximum ROF is 6.67 discs per second, which is excellent considering its the only slam-fire blaster to do so, it rivals semi auto blasters like the Rayven and Hail-Fire, and is only exceeded by the Magstrike and possibly Rapid Fire.
