My second try at owning an Enfield...

[Baal]

There is a tool available that hooks over the sight protector and allows you to adjust the front sight. See attached photo.

I've seen mention on this site of folks who make their own tool. Maybe someone will chime in with how to do that.

For elevation, you can change the mk2 rear sight to a mk1 style. Or if you want to keep the rear sight, you can try a different height front blade.

The Lee Enfield sights are calibrated for a 174 grain bullet with a muzzle velocity of 2440 ft/sec.
