Post Rifles & Sights (Open sight) or aperture (closed sight)
'Twas said the Lee Enfield is a battle rifle, the Mauser a hunting rifle and the Springfield had sights designed for target shooting, not for combat.

SMLE (NO. 1 RIFLE) Sliding tangent battle sight mounted on the barrel.

Mauser 98, tangent V-Notch battle sight.

Lee Enfield No.4 Mk. I, has two peep sights. Flip-up battle sight and a Ladder Peep Sight, used for precise accurate targeting.

Tang-Peep Sights & vernier scales on Sharps black powder era target rifles in existence from the the mid 1800s.
Diopter is an 'Aperture Sight', also known as a 'Peep Sight'.
Aperture sights are used on hunting & target rifles, example; the Springfield 1903 & A3, the M1 Garand, the No. 4 Enfield, the P. 14, M 17, post WWII assault rifles.
Diopter meaning 'view hole', the Springfield A3 has a 'small aperture' fully adjustable peep sight with 'elevation and windage'.

Target sights/target diopters sights usually with an adjustable occluder. Rotating disk and H&K type rotating diopter.
Aperture target sights normally are more adjustable from 0.5 mm to 3 mm - often in conjunction with a front globe sight which excepts a choice of insert elements - circle, concentric circles, post element, etc.

i observe a bit of sight paralysis of the pinnules :lol: :lol:

The term diopter (Greek dioptra, from diá = through and opteuo = I observe) denotes any instrument fitted with one or more perforated sights through which observations can be performed.
Before the dissemination of Islamic astronomy in late medieval Europe provided a specific term, diopter also designated the alidade, i.e., the small revolving rod (Arabic al-'idada) pivoting on the center of the goniometric scale engraved on the front or back of many ancient astronomical and surveying instruments. Two pinnules, called sights or pointers, are attached at right angles to the alidade. They are fitted with holes for aiming at a selected object. An index—often consisting of the edge of the alidade itself—shows on the goniometric scale the angle between the line of sight to the targeted object and a predetermined direction. With astrolabes, for example, the preset direction is the vertical of the observation locality.
