Well i think we were on the nail with sightron clone. Testing today on repeatability was very good with the small rowan universal on. Decided to stick my spare sightron large snail wheel on. Strangely all my range markers on the sidewheel down to 35yds were spot on lol. Not done the rest yet as still playing with it. Scope is bright ( as per sightron ) Narrow field of view on 50 mag ( as per sightron ) Snaps in nicely ( as per sightron ). Will continue playing later as its persisting it down atm.
