No. I cut all the wood myself, cut it down to the right proportions (waist height for the stock/tiller, knee height for the prod), carved it properly to shape, cut the mechanism into the stock (rising pin trigger), cut the groove for the bolt, fitted the string, tested the prod, made some quarrels and then test shot it. Adjusted it accordingly (string length, &c), and then shot it properly. It is accurate. Go to
www.atarn.org for information on Chinese crossbows, amongst other things. (You will want to click on "China", then "the crossbows of southwest China". You can also find out about many, many other things on there. It's a great site).
