“My experience of this crossbow. The hole in the stock for the limb is too small so the limb doesn't fit properly. It is necessary to have two people to fit the string. The bolt retention spring makes the bolts point upwards away from the channel, consequently the bolts fire upwards. The sights are way too high to be of any use. I have never managed to get two bolts within 6 inches of eachother when aiming at the same point, with both plastic and aluminium bolts. The safety works well.
All in all this is a terrible product and even though cheap I would not recommend it for accurate crossbow shooting.”
