Looks non traditional but I bet it works good
I have the 1.5-4X28 IER on my Trapper. It surprised me how well it does work, both in getting on target and balance. I also have a Guide gun with a 2.5X20 UL on it and have had 1-4X20 and 1.5-5x20 scopes on it.
With the shorter eye relief and some rip-snorter loads, my forehead sometimes worried. With the Ultralight and especially the IER, no worries. Both are in QD rings so when the mood strikes, I can use a peep sight.
Trade-off was a slightly tighter eyebox with the longer eye relief, but nothing like a pistol scope.
My forehead thanks me.
