The coyote and feral dog problem had increased and the 308 would increase the range, so I took 'er down and checked the scope at 80 yards. With the Vortex Viper scope on the AR10, I figured it was a good starting point. I fired a three shot group and...
Moved to 50 yards and tried again. Same results. Three shot group, not a single shot on the cardboard. I was stunned. This was a top brand AR, and I had cleaned and lubed the gun PRIOR to taking it to the range. I moved to 25 yards and shot offhand at the target. Still no hits using the scope. Set up for boar, it had metallic sights offset at 45 degrees in case a boar came charging from the brush. I tilted the gun and used those. Three shots.... in the black. No more shooting for the day. At more than $1.25 a round, I had my answer for now.
I ordered a laser bore sighting cartridge for 308 and waited. It arrived while I had a house filled with family for the holidays so I put the kit in the gunsmith's box and waited some more. I got 'er out today and checked the bore sight on the scope. It was a foot low at 20 yards, sighting down the dark hallway in the house to check the scope.
This is the Vortex Viper 2.5 x 10 x 32 Tactical Precision Scope with an illuminated reticle. Retail on the scope is $1,000. (I see them on sale on line for $800) They have an unconditional lifetime warranty, but I bought the rifle used with the scope mounted on it, so the scope was acquired use. I told them that in the request... I didn't try and BS them. Still, if I have to pay $200 for repairs I come out way ahead. Hopefully Vortex can repair the scope for me.
