The best advice I can give you is to call David Wilkins at Wyvern
Creations 603-659-0575 probably the best all around and most
knowledgeable person there is.Very good to talk to and will shoot straight on any thing you need to know about crossbows!
I live in south east Missouri and only buy from him and another
fellow in Ohio.The man is second to none when it comes to all
things service,prices,qualilty,etc.Well worth the call you wont be
sorry you did!
