well i went to the range to day to site in my new remington r-15 in 223. i get there and get set up and start shooting. the rifle is shooting awesome... 1 inch groups at 100 yards. but its shooting 6 inches high and 4 inches left. no big deal i make my adjustments. next 3 shoots are dead on as far as left and right but still 6 inches high (thought i might have forgoten to make that adjustment) so 20 clicks down i go..... the next shot is in the exact same place as the last 3. so i try again 20 more clicks down and nothing changes. well i pack everything up and come home to clean the rifle. while cleanining it i mess with the scope and notice that the vertical adjustment turret is not "clicking" when i try and adjust it. now this scope has not been abused it sat on top of a 308 for 4 or 5 years and only had maybe 300 rounds thru it and these were the first 8 rounds out of the r-15. i guess the question is would this be covered under nikons warrenty?? or would i have to pay to get this fixed???? it is a nikon tatical 4-16x50
