here is a few pics of my $4 laser sights that i have mounted on various rifles
and shotguns. this is my T/C R55 allweather 22 LR. i bought 2 dozz clearence
price laser levels at crappy tire, u allready guessed, $4. the light itself is a few
thou over 5/16 in od and about 3/4 in long. i put a piece of heat shrink tubeing
over it and glued it place after i had the holes drilled and tapped for the elv and
windage holes. this is a plastic stock so i drilled and tapped for #10-24 and
installed #12-24 screws. just like nylock nuts, the screws stay put this is not
for bright sunlight but for low light like inside a barn. great for squrrils. my
mossy has twin lasers that i call snake eyes. a real ally sweeper.
cheers
