Platinum piece of mud - Primary Arms 1-8 x 24mm LPVO Rifle Scope

I zeroed this sight in with a laser. Was not able to really test it at the range because of Spinal Surgery. when I took it to the range, mounted on a custom built AR-15 with a match grade barrel. the scope would not keep a zero. I thought it was human error, a $1200 scope that once zeroed, and 2 shots later, was off 4 inches. 90 rounds was all over the target. I removed the scope and placed an Eotech EXPS3, what a difference, 1/2 inch MOA at 75 yards. 90 rounds later I shot out all the centers of the targets. I removed the Eotech and put the PA back on, and it was all over the target again, even when mounted on a sled. I do all my setups with a solid sled. This is $1,200 of junk. I buy most of my scopes on Optics Planet. This Primary Arms Platinum Series 1-8X24mm FFP Riflescope was purchased May 15 2017 as a Birthday gift to myself. I bought the PA scope and a Sig Sauer Tango6 2-12x40mm Riflescope. thats over $2,000 and the cheaper Sig is a better scope.
