Rear sight assembly for 3/8″ rail
This rear base assembly also fits the Iver Johnson M1 Carbine and Erma-Werke M1-.22 LR carbine rifles.
Lewis Billig – November 9, 2016:
Purchased for my Erma M1 22. Fits perfect, looks original. Seeing as how difficult it is to find the original sight, this makes for a suitable replacement. Very satisfied.
Not that bad
