Should have know better - VISM Eco 4x34mm Illum. Urban Tactical Rifle Scope VECO434QRT

Purchased this for a starter sight for my .300 blk out, mounted it and boresighted it just fine. Excited about trying it out, had my doubts as it was NC Star product but wanted to give them another try. I liked all the features and the reticle was what I wanted. So first time out shooting the sight lasted 5 rounds before the reticle jarred loose, so now it has rotated and is at a angle making it unusable..... total waste of $200 , should have just got a vortex. Have yet to have any good luck with a NC Star product yet. Save your money and buy a better product. As a note 400 rounds through my vortex strike fire ll and no issues compared to 5 rounds and a failure. So now a junk item sitting in safe waiting to so if they will repair it.
