I know this an old thread but Nikon has a new scope for your crossbow. I have been using Nikon's BOLT XR for years with great success. a few deer and over a dozen hogs, still no opportunities on a gobbler yet, hopefully, one day soon! One of the best features is being able to utilize Nikon's Spot On Ballistic Program to dial in longer shots. Easy to set up and with a few shots it is easy to understand how the BDC reticle helps increase your accuracy. I have been doing freelance work with Nikon for almost 10 years now and I have helped a lot of folks choose Nikon's BOLT XR with not one complaint. Nikon just recently made a few changes to this scope and it is now called the P3 Crossbow Scope 3x32 BDC 60. Some nice changes with aluminum capped turrets and laser engraving. Cleaner look and same great function and price. Backed by Nikon's No Fault Warranty too.
