I heard about this item from a friend and went to their web site to learn more about it. I took one look at the video of this item in action and was hooked on the idea of using it. It's primarily used on the video with a Tippmann a-5, which is what I have, presumably due to the reliable feed of the A-5 Cyclone Feed System.
I bought it and the shop owner was kind enough to give me a 500-round bag of paint to test it with. Installing it was a little bit more difficult than I had thought. The device works by pushing a flat tab backwards into the trigger, which is kicked back into the crank by the trigger return. this happens four times per revolution of the crank. I had to position it carefully and cut the tab to fit my trigger. This requires disassembly, but there is a perfectly clear picture of how to do it on the packaging. This requires the included allen wrench and one smaller one whose size I don't recall but I found by trial and error. Once done, I pulled the trigger frame off the marker and attached it easily with the provided allen wrench. Then I re-attached the trigger frame and was ready to rock. The set screws did scratch my trigger guard, but it's a plastic Tippmann 2-finger guard, I don't care if it's dinged a bit and the Crank covers it anyway.
I gassed up the marker and went out behind the shop to the test range and unloaded the whole bag of paint with the crank, less about 5 shots I did firing manually to confirm I could still single shot without the crank being an interference. It worked fine in both modes.
Using it is different from normal firing because the position of your firing hand has to change. Because the marker will tend to mvoe more than if you are pulling just the trigger, you need to keep the marker tucked in tightly to your shoulder to brace it. If you do that it will move pretty much the way it does when firing without the crank. The amount of physical force needed to turn the crank is very small. If you lost anything by way of accuracy, you can make up for it in sheer volume of fire. Because keeping it rucked in tightly is requried to stabilize it, this unit will probably have a tougher time working well on markers without a stock or which use a remote because you cannot easily tuck them in.
This tool is most useful on markers that are difficult to shoot quickly. If you can already fire your marker faster than 12 BPS because it has a very light trigger pull and you are very skilled in walking it, there's no reason to use the Firestorm Crank. If you are using a mechanical marker with a heavier trigger pull, this item can drastically increase your rate of fire. Without disrupting my ability to shoot fairly straight I can turn the crank three times a second easily; if I want to push my luck I can send it around four times though that will tend to make the marker move a bit more. Still, without this crank there's no way I would get my mechanical A-5 to fire 16 BPS, which it can do with the crank.
Gives great ROF increase. Not useful on markers that already fire 12+ BPS. Works best on markers taht can be tucked in tightly, so markers with remotes and no stock might have a hard time with it. Should come with allen wrenches for both sizes of screw and a pad to protect trigger guard finish. Overall a wonderful item for low to medium mechanical markers .
