I bought this sight for using on a 25m outdoor range with paper targets for FX Impact with this benefit M4 .22. However after zeroing realised it is way beyond what I need. So I am selling it as virtually new used once only, it is boxed with all components per photos. ideally for longer range, hunting. Easy to zero, change settings, solid built latest generation. Integrated IR torch, lights up to a good range, at 50 yards got 10mm grouping low wind sunny day. Bought from Goyojo direct, £275 3 weeks ago, selling for £225 so I can get a traditional sight.
