Keith Lewis: the new englander and the gray hawk are the same guns except for the rifle twist and stock.The rear peep has more then enough when it comes to elevation corrections. There is a bar that the peep fit into that has a set screw to move for up and down for height (more then enough)
I found that you will have to set the peep about 1/2 back from the first hole on the rear tang,t/c states to use the last acrew on the tang and redrill one screw.it won't work you have to dig your check into the stock for proper aligment.
I did drill two new holes into the tang very simple job but you will need a drill press,also you would have to buy the peep that fits the new englander .
