Saw a Nikon elevation turret break off today. There was no visible abuse to the scope, and the adjustments appeared to be working previously. I have never seen a failure like that before, but it reminds me why paying more for some brands is well worth it.
I got to try a Sightron 6-20 power scope today. The Sightrons are gaining popularity here as a cheaper alternative to Nightforce and Leupold. I am not sure which model it was I was given the chance to use, but the clarity was great from 6-about 14-16 power. As the power was brought up to 20x, the picture clarity and crispness declined. At this point I do not think I would recommend a Sightron for a fighting rifle. However for a range gun or target/competition rifle, it may be an excellent economical choice.
I also got to look through an IOR 2-12 power scope. I believe the model was the Spartan. What I thought was most interesting was how compact this scope is. Many tactical scopes end up being large. A 3-15 or 5-20 tactical scope can be rather large and heavy on a smaller rifle like an AR15. This smaller scope would be right at home on a smaller lighter rifle. The power range is also good for closer range work. I have found that shooters(including my self) are slower at finding close target with 5x and up. The top end of 12x along with the scopes clarity allowed me to easily find and see 8 and 10 inch steel targets at 1000 yards. This compact scope appears to be one of the ideal choices for the compact lightweight 5.56 or 7.62 sniper system.
