Great features but didnt hold zero - Athlon Optics 4.5-27 x 50 mm Rifle Scope 30 mm First Focal Plane (FFP)

Scope has lots of great features at a reasonable price. I thought the glass was clear, illuminated reticle was clean and crisp with the light on. Turrets were great even though some people complain of them being mushy. There is a O ring that can be taken off to change the feel of them if you prefer. I took off my $250 scope and got this new one mounted and could not wait to get it to the range. Once I got it to the range I found that it would not hold its zero. I was shooting about 5" groups. I put the old scope back on and was able to quickly dial it in to 1" groups. Spent lots of time on it and wasted more ammo that I would have liked too only to be disappointed. I know some people like them and have had good luck. Unfortunately the quality control did not catch this one and I ended up wasting a half of day of vacation and burning up a bunch of good ammo. Hope that Optics Planet will give me money back instead of store credit.
