I used Harris from 1984 to 2015. In 2016 I shot a couple antelope and a deer with a $17 imitation harris from Amazon. It worked just fine. All my previous attempt to deviate from Harris had failed.. ok the Atlas works, but all the cheap deviations.

I own ~~ 10 Harris, and I will be back with them next year, but there are alternatives now.
