Great scope for a great price - Killer Instinct Lumix Speedring 1.5-5x32 IR-E Crossbow Scope

On my killer instinct ripper 425 this scope is very close to being accurate at longer ranges after sighting in at 20 yards. There’s a review saying it’s useless because the magnification ring is the same as the speed ring and claims you cannot zoom without affecting bolt speed…. These people shouldn’t own a crossbow, your scope has no effect on FPS of the bolt and imagine this, as you increase zoom for longer range, longer range means decreased bolt speed so it accommodates for speed drop to give you a bolt speed estimate. You don’t use this scope to increase or decrease speed and I would hope you wouldn’t have to ask a question like that. All in all great scope for the price and most bad reviews come from people who simply don’t understand how optics or crossbows work….
