This invention relates to improvements in
nected -to a part of a firearm such as a receiver
sights for firearms and more particularly to an
I3, or the barrel thereof, as indicated in Figure
1. The base II is generally U-shaped in cross
adjustable rear sight having improved elevation
and windage adjusting means in its structure.
One object of this invention is to provide in
a rear sight for firearms very eñicient elevation
and windage adjusting means of improved form
and which is comprised of a minimum number of
components.
Another object of this invention is to provide
a rear sight for a firearm of the above nature hav
ing a sight leaf adapted Ito be elevated at one end
and means at its other end adapted to adjust the
elevated end laterally.
A further object of this invention is to provide
in a rear sight of the above nature, a sight base,
and a sight leaf which is so resiliently connected
to the base as to be substantially floating in re
spect thereto.

Floatingly disposed between the side ñanges ‘I4
and I5 is a sight leaf I6 having lugs I'I and I8
extending from each side and at substantially the
center thereof toward and into engagement with
.the side flanges I4 and I5 respectively. The
outer edge I9 of each of the lugs I'I and I8 which
is in engagement with the respective side flange
is arcuate in shape, the radius of which is sub
stantially `one-half the dimension between the
opposing surfaces of the side flanges I4 and .I5
whereby the leaf I6 may pivot laterally between
these flanges about the center of the arcuate
edges I9.
A still further object of this invention is to pro 20
