Screw a junky Excalibur scope. I bought the tact zone and sent it back because the coating flaked off the inside of one of the lenses and stuck to the rear glass, or at least that’s what Excalibur told me. I sent that one back 2 years ago and upgraded to the twilight dlx for $80 and it won’t hold zero for more than 4 hunts (cost me a deer this year due to a shoulder shot from being off 2 inches to the right) and I’m very careful with my scope not to bump it on anything. If that’s not bad enough, now there is condensation on the inside of the scope for some reason. I’m going to send this one back and try to sell the new one and I’m getting a hawke. Everyone i know who has a hawke loves it and never loses zero.
