Try GunPartsCorp or Jack First. You will first need to identify the manufacturer since JC Higgins only marketed the guns.

From the end (where front sight is located) back to where bullet enters barrel.
the ranger Mod 34 was made by Marlin mod 65 e-GunParts.com
Depends on the exact sights used. The most common are a rear notch sight, and a front post. The post should be centered in the rear notch, and the top of the front sight post even with the top of the rear sight. Point of aim is usually the center of the target.
The front sight is called "the front sight."
Probably not. However some pistols can be fitted with an aftermarketlaser sight.
i own a M1 carbine pistol production made by Iver Johnson standard rear sight with a modified barrel band / front sight, which to say the least is hard to hit anything with, but its a lot of fun. As for much more info or variants of this weapon, i have no idea and myself, have had less then perfect luck finding information on it.
better to ask, 'can I fire this pistol' ?? If ever in doubt or not sure, take pistol to gunsmith to check it out as a firing pistol. You need correct ammunition. Modern pistols fire modern bullets. Older pistols, like from 1870's, may require black powder bullets. Your pistol is probably marked as to pistol model and date. If not, the make and serial number can be checked to determine date made. If the inside of your barrel is black and debrie filled, don't shoot it. they is why you seek a gunsmith.....the last part is sight and alignment. that is put the front sight between the rear sight and put on center of a target. slowly pull back on trigger until pistol discharges. keep finger OFF trigger until ready to fire.................lots more, but this is a start............
1. Remove the screw to the rear of the front sight ramp.2. Remove the "blade" from the front sight ramp.3. Remove the screw from the front of the front sight ramp (which was formerly seated under the "blade").
line up the target on the top of the front sight while sighting the front sight through the rear peep sight.
