FSFF .625 Blowgun Long Range Sight and Replacement Cone Kit for Darts, Big 70 Pack, fletched fit All Steel 2 and 2.5mm Cold Dart Shaft, snap Sight on All Blowgun Tubes Great Accuracy Distance Cones

Note to the manufacturer: I hope you read this so I am putting these comments first. I’ve done an extensive amount of blowgun research and testing so I hope that my observations will carry some weight. This sight system is by far the best and most innovative blowgun sight available that is competition-legal, and I hope that the blowgunning community will realize the importance of this product. However, the stems that hold the fiber optic cable are very thin and easily bent or broken — please make the shafts thicker and stronger. A thicker diameter fiber optic cable would also be brighter and much easier to see than the small diameter cable that’s included, and providing different color cables would be a nice touch. Consider offering this sight in .50 caliber as well — a much more popular caliber for competition than .625 — or possibly including several simple plastic adapter rings that will allow this sight to clip snugly onto a .50 caliber blowgun. Thank you for your highly innovative products and for consideration of these observations.Review Summary:– These fletched dart cones provide a small (about 15%) but statistically significant improvement in accuracy.– This sight system is the absolute best allowed if you are competition shooting, but requires some setup and sighting-in; if you are not competition shooting then a laser sight is by far the most effective sight option (search for “Add a Blowgun Sight!”).Full Review:This is a bit of an odd package that includes both fletched replacement dart cones, and an innovative blowgun sight system. First the cones, as I suspect that is what most blowgunners will be most interested in. They’re generally well molded with little flashing. It took me a while to finally get around to actually testing these, and I will say that true accuracy testing of a blowgun or dart is extremely difficult. If you buy this package, you are not going to shoot 10 darts and notice a dramatic difference! There are so many variables, the biggest one being blowing consistency, that the only way to conduct a valid test is to perform a scored target series and run statistics to see if your data demonstrates a significant difference. I used Cold Steel Mini Broadhead darts and Mini Broadhead shafts on the FSFF cones for my comparison. The FSFF cones weigh slightly more than the Cold Steel cones so the darts were about 5 grains heavier, but actually had the same velocity (126 fps with a 5’ blowgun) when I chronographed them — so the FSFF cones may actually be slightly more aerodynamic despite the added fletching. I shot about 25 complete target rounds with each dart, and very early on noticed that I was definitely hitting the bullseye a little more often with the FSFF cones. Overall from more than 200 carefully-scored shots I got about 15% more bullseyes with the FSFF fletched cones. Actually running some statistical tests on the two data sets, the improvement was statistically significant (valid with a 95% confidence interval) by a very narrow margin — but considering how similar the two darts and data collection methods were this is actually really saying something. The bottom line is that these FSFF fletched dart cones are more accurate than Cold Steel dart cones, and PROBABLY also more accurate than most other standard .625 dart cones. These might also provide an even more significant improvement in accuracy for razor broadhead darts, which I have found vary more widely in performance than other dart types, but that is a much more complicated test for another time.Second the sights, and this is really the important piece of this package even if that’s not obvious from some other reviews. The significance here is that this sight system is legal for blowgun competition shooting (unlike laser sights, which I consider to be extremely effective but are not allowed for competition). It will take you some testing and practice to begin using this sight system, but for anyone who is not a simple instinct shooter this is the best commercially available .625 blowgun competition sight, PERIOD. For competition you are usually shooting at 10 meters, and after sighting in my blowgun for that range with the appropriate “pin,” I made one modification by cutting the other pins off. Use a small piece of electrical tape to EXACTLY mark the sight’s position and orientation on the barrel so you can pop it off and back on and still maintain your “zero.”Note that many “instinct shooters” who do not use sights are attracted to blowgunning, and if you are in that category I envy you, and this sight system will probably not help you. However, instinct shooting cannot be taught, and for the large majority of shooters a sight system will provide a significant improvement. Note that if you are not competition shooting, I have found from testing a wide range of blowgun sights that a laser sight is the easiest and most effective by far, and for more information search for “Add a Blowgun Sight!”The bottom line is that this is a VERY interesting and worthwhile .625 blowgun package for the serious blowgunner to experiment with, both for the fletched dart cones and the sight system.

Seams to be a great company and the cones fit all the other brand darts well. I hope I can afford to try there darts. It seams you get what you pay for! Either way, thank you!

The sights are pretty useless. Besides , you really don’t need a sight on a blow gun, knowing how to aim and breath control is all you really need. The cones are good, they don’t receive damage if you shoot another dart on it. The Cold Steel cones are great until you get a dart through them and then you gotta throw them away.

Sights are useless, blowguns are instinctual, but really good replacement cones and good for making carbon fiber darts

The dart cones were the only thing useful in the pkg! The sights were useless!

10% accuracy improvement- caps desired, sights not.

I would have rather they gave you more cones and maybe just one sight. I really just bought it for the cones anyway. Quality is great and if your into the BG sport your gonna need replacement cones at some point. So far quality it great and they seem durable. I'm pretty sure I'll be buying another pack at some point in the future.

Love the cones. Improved my accuracy. Fits nicely in barrel and on the dart. I dont use the sight, too many years of instinctive shooting is hard to replace. It may work for you, just not my cup of tea. Sell the cones by themselves, please.
