Question: what is the bow made of?
Document: This prevents slipping from happening.Be sure to buy someLube Waxfor maintaing bowstring life.When mounting the string to the ends of the bow, I found the best method is to have some help, the first couple of attempts probably won't work, but keep at it, the bow will eventually loosen up a bit, but don't put your foot into it and try lifting up on it, instead put the butt of the Xbow onto the seat of a chair and push down on the bow to bend it, if possible putting all of your weight into it while your help hooks the other end.
I was expecting some cheesy plastic crap, but no, the black is metal, the brown is wood, the bow is some composite material similar to the bow on my TAC-15i XBOW. Cocking the string is easy, well for me that is.Best Arrows for this are:6 Aluminum Metal Arrows 14" Long Brand New Crossbow ArrowsWhen assembling it, there are these 2 little black sticky squares, one goes on the bow between the two white lines, the other goes on the compression plate's backside opposite of the screw-hole indention, so that the two rubber parts will touch when tightening the bow the crossbow.
This crossbow was a lot better than i expected when i ordered it. It is of metal and the stock is made of wood putting it together is simple except for stringing it.
The string catch doesn't function ,neither does the trigger. Can't cock it, no customer support and a craptastic return policy. No manual, just a pictogram set of instructions. I've had $20 toy crossbows from Bub-K that worked better and were better made than this blazing POS.
The string that it comes with is crap and isn't waxed properly but those are minor, but I did find some sort of cracks near the prong but thats just the cheap rubber stopper for the bolt. The bolts them selves are cheap and I recommend you buy more. The sights are awful and are hard to take off because of the cheap screw that it uses degrades like rust. But this is a all wood and metal crossbow and is sturdy and is very powerful, yet there are some flaws.
Solid wood like a quality rifle. I had to zero it in before I could hit a target, but  a lot better than I expected for the money. Very hard to string, but if you want power, you have to deal with that. Very pleased with this crossbow.
No instructions, broken arrow , had to fine someone that knew wat he was doing to put it together not happy
It is a wonder piece of equipment.I did have a little difficulty cocking so I bought the recommended the pulley. I inserted the supplied Hex wrench behind the scope for better leverage.
Answer: yes
