Steiner m536 works - Steiner M536 Prism 5x36mm Rifle Scope

I purchased this 7.62 scope during the Black Friday sale. As most of us might do, I mounted it and admired how it looked on an AR-15 5.56mm platform. It's larger than what the online pictures show, in a good way. A nice weather day finally arrived in Pennsylvania, in mid December, so I prepped my rifle on a bench at the range, with two leather rifle sandbags. I used a 20-round PMAG magazine with 223/5.56 ammo, the barrel was a 16" stainless Wylde 1:7 twist. I achieved success with less than 10 rounds. Steiner's factory settings were pretty close to zero. At 100 yards, not using the scope's illumination, I aimed the scope's dot in the reticle to the bullseye on the paper target. I squeezed off 3 rounds. I then aimed at a 12" round AR500 steel plate, 200 yards away, and missed it. I walked to the paper target, and was 4 grid boxes to the left of center. I adjusted the horizontal dial 4 clicks. 3 rounds later, I was 2 grid boxes directly above the bullseye. I adjusted the elevation dial 2 clicks, and popped off 3 more rounds. I hit the bullseye with one round, and the other two rounds landed slightly to the left, within 1 inch of the center. This 3-round triangle shot group was 1 3/4 inches tall and 7/8 inches wide. I hit the 200 yard steel target successfully 4 more times. The Steiner scope was sighted in, for less than $5.20 in ammo. I used all 20 rounds, and was done for the day. There was a very light wind, and the temperature was 42 degrees and sunny. The range was surrounded by leafless trees, with the targets gradually located/placed uphill at different ranges. I was impressed that the factory settings were very close to zero, and a 7.62 reticle scope does work on a 5.56 platform at 100 yards. I will use this scope on a 7.62/308 platform in the future. A few minutes later, I took 3 shots at a 75 yard paper target, and hit the bullseye 3 times. The 3-round shot group triangle was 1/2" x 1" x 3/4". I fired 3 more rounds at the 100 yard target, and hit slightly below the bullseye, 2 grid boxes underneath. One round was 3/4" away from the exact center of the bullseye. I was very satisfied. My next goal is to find a range with 500 yard targets, to test the lower lines on the reticle for vertical elevation. I would recommend this scope. You will need a spotting scope at your bench if you don't want to walk to your targets to see how well you aimed. At 5x magnification, it is very nice and worth your hard earned dollars.
