great,get extra pack of the light tubes for the front sight..i think he only sells front sight in RED,i could not see red as well as i could,GREEN..

you take match to melt the new tube in front sight..GREEN is best..

remember,the rear sight mounts in the same spot as your original sight..he has about 10 different models, depending on your type of gun/barrel..

if you can see ok in this location, great, it will not be real clear, your eyes cannot focus on 2 objects as we get OLDER..

BUT, if you want it clearer on rear, try what i said, lay it on barrel and move it towards the front sight until it looks clearer..then have your gunsmith drill/mount it there..

thats what i did even tho you dont have too,but i wanted it clearer..cost me 14 dollars for him to drill hole in barrel..if i dont like it, i just move it back and put screw in hole..

just remember, your gunsmith may have to make hole bigger in rear sight ,you may not have too..

i like smallest front sight i can put on my gun..that front sight from RMCSPORTS is real small but i may make it even smaller or have him make it smaller for me..
