my rear sight on my t/c hawkins is about 6 and 1/2 inchs from breech.i have v-peep from rmc.it is blurry.rmc said this is normal and as long as front sight is clear, no problem. i would still like clear rear sight. after moving it out to 10-12 inchs towards the front sight, it gets clear. did any of you ever move your rear sightand was there a problem. my gunsmith says this is what you should do as our eyes get worst with age.i think i will do it but thought i would ask before having it done.
