with the V-PEEP you can do 2 things, you can use the opening in peep at top and sight over the front fiber which will let you see target at 100 yds.this will center the sight in the peep as normal is done, you could do that. i am trying to place the front sightdown in bottom of the v-peep or as i said,BURY in bottom ,then i use the opening in v-peep to see target, so far so good. look at picture of the v-peep that cayagug put on. see top is cut out.you could sight right over it but i like BURY in bottom ,so far. still testing sight but will be able to give more as winter has set in and i am done until april. but so far, this sight is better than anything i have used so far. and its LEGAL in pa. as it is not a FULL PEEP,its a v-peep, ha. good day.
