what causes nicks/dings/chew on bolt face

[pump]

geez i just found out what it is

the bolt hits the top area of the detent hole and feedneck milling

so i need to find out why the bolt is pushed up and to the right...up and to the right...up and to the right

i think it was my on off shims pushing the top of the body higher
ill take them out and see what happens....to borrow my friends lvl 7 bolts they never use

WTF

What type of body do you have?

[mr doo doo]

hmmm, maybe either the trigger frame screw or the field strip screw is in too tight, causing something to warp...like the rail or the body. just a guess...

Check the trigger frame screw is to tight or to long.

lvl7 ULE body

Check that the pim on the bottom of the body is not too long and bottoming out without letting the body sit tight against the rail.

well i htink its the combo is an over tight frame body screw, and the on off shims i put it

it was sticking down a bit more than it should of been forcing the valve up, and the body down


my pin is not that long, its just right, but i like to time it as long as possible to save the bolt and sear
