Question: Do these crossbow  bolts have flat or crescent nocks?
Document: Six(6)2219 camo bolts with orange vanes and orange moon nocks, comes with 100 grain field tips, faster than aluminum bolts, great buy!
If you have an Inferno crossbow, these are exactly like the bolts that come with the package. I am very pleased with this product, they are not only carbon bolts but are camo and have the same fletching colors as my other 4 bolts. I would recommend these to anyone for anything.
Cheap bolts and you do get what you paid for. The tips easily separate from the bolt itself. The fletching becomes misshaped after a few shots into a target and then you cant be sure their direction. they do shoot straight while they last. I would say this is an okay product to buy for a new crossbow owner just learning.
Good price. Arrows helped get my first deer with crossbow. Went through deer and into tree trunk. Arrow still as good as new.
I am still learning the Crossbow and these arrows just didnt seem to last too well. they might be better once the scope is lined up correctly will give it another shot that is for sure.
We own the Barnett Jackal crossbow and these arrows work great. Just as good as the more expensive brands. The price has increased since I purchased these a month or so ago but I'll be watching and when the price comes back down to what I paid for them originally I will buy another pack. Item arrived promptly. We would highly recommend both the product and seller.
Great price. Only dislike is the tips can come lose somewhat easly but other than that the bolts fly great.
This is the pack I wanted. I love them. Now I have plenty bolts when I go hunting with my family
these are perfect with the inferno cross bow, they have the same camo pattern and fire well, they are longer than the aluminum bolts that come with the inferno but are much lighter.
Low quality bolts. Good for practice but would not use them for hunting. They are my least favorite bolts out of serveral brands I've tried. The Camo pattern is a nice touch but why have Camo for practice quality bolts...
Answer: yes
