You'll need a cocking string and a de-stringer. Buy you some of their Fast Flemish Strings, you'll pickup an additional 15 to 20 feet per second. Don't bother with silencers, this thing is son fast that no deer can jump the string under 40 yards. For the best scope and price get the Hawke Optics Crossbow Scope. Less than $100 and perfectly matched to the speed of this bow at 20, 30 , 40 and 50 yards. I would look at the new cheep piece that Excalibur sells for these bows, it makes the bow more comfortable to shot. Use their bolts and broadhead, very very accurate. I have Robin Hood three already at 40 yards. This will bput an arrow completely through a deer at 40 yards and never stop, ULTRA FAST!!!!!
