Even tho' you're supposed to be able to adjust these sights with
nothing more than a round of ammo, folks who've tried know it's
just not that simple. This decidedly handy little Sight Wrench does
the job, quick and easy.
SPECS: 1-3/8" (3.5cm) long x ¾" (19.0mm) dia. Blued
steel. Models for A1, five-prong (adjusts front and
rear) and A2, four-prong.
