Been a while, but like the Leather Project, Weather had delayed everything. The ice and snow had covered the range, and Miss T didn't want me on the range then, and after the melt off, it was muddy. We had a week of 70 Degree weather so I was able to get out to the range. My first attempt at sighting in the AR10 didn't go so well. I had purchased that Laser Bore Sighter, but it did well inside, but was useless on the range in bright sunlight. Maybe the two sets of included batteries were old. :evil:

I couldn't get on the backer to see where I was shooting and was having a bad arthritis day, so I packed the gear away and waited. In preparation to test the rifle if I couldn't bring it on target, I took a SIG Red Dot with me today, and got set. We have a pair of bathroom overhauls in progress, so I had a 4x8 sheet of cardboard on hand. I put the sighting target at the bottom of that sheet and squeezed off a couple rounds. I started about 30 yards back.

Way High and Right. Started walking in the scope in. When I got close, I moved back to 50, then 75. I moved off the sighting target as my aiming point to a black marker dot, aim small, shoot small. Got 'em Tighter. Moved back to the target, and Fired three shots. First was in tight. Pulled the second. (By this time I was hurting... ) Deeeep Breath, let it out and relaxed, squeezed that third shot and Boom.... in there. Done for the day. With practice, LATER, this could be a real shooter. I'm satisfied. The good thing is, I'll have rapid second shots on a running target, or pairs of invaders to the coop.

The New GEN II Vortex Viper mounted:

The target - two in the center, the first and third shots. That low shot at six was a called pulled shot.

A close up view of the two in there... not a bad group at 75 yards... for a new platform with a new scope.

I put the SIG Red Dot back on the Classic Marlin for Miss T. It was her Dad's 30-30, she or my daughter may use it for Deer this November. I'll get it sighted in with a quality deer load. For now, I'll clean up the AR and load up a Mag with 10 rounds or so, and stage it handy, along side the shotgun stoked with slugs. A choice.

Glad to see you have everything all set up now. I'm a fan of that PEPR mount too, and have two of them on AR15 platform uppers, mine are the 30mm ones with the poly inserts.
Once the weather moves more towards springtime, and you get more trigger time with your new rifle, I'm sure you'll enjoy it even more.
