The best Enfield No.4 Mk.I rifle battle sight has a combined fixed aperture plus an elevation only adjustable aperture sight. Enfield No.4 Mk. I target sights I have seen that have windage and elevation adjustments - and fit existing sight base on rifle's receiver with minor machining of that sight base - have no fixed battle aperture.
Is there a procedure or routine gunsmithing that alters the adjustable military sight combo to incorporate at least some windage adjustment?
If there is no way to incorporate any windage adjustment in the best of Enfield No.4 Mk.I rifle sight, is there a third party or after market sight that has both battle aperture and windage adjustable tip-up aperture?
