been out of the tech game too long and staring to catch up

can somebody provide me with a pic of a lvl 7 foamy bolt ? or a link to a pic ?
What bolt is this ? Im assuming its a Lvl 7 foaminess ?
Has anyone tried to cut away @ the triangle tip , to make it flat ,and glue on a foamie ?
I feel that my bolt may be hitting to hard
i just ordered detent's in case this one is worn , may have been contributing to the double feed i would also
get once and awhile
