Aut cum scuto aut in scuto
Excellent indeed. I would be curious to know if when raised, the sight clears the bolt travel. For that reason I have not installed one on my Marlin 336. I am instead in search of an old timey receiver sight.
Properly installed, the bolt travel will not strike the sight. Thus the reason for such a set-back on the stock.If you want to install one on yours, then you probably need to find the specs and play buttstock roulette or take it to a competent gun-smith.
Yeah, I'd like to have that sight.
