Any tips on removing the Bolt?

My son called(could not send picture) can't figure out removing the bolt.

My suggestions as to trigger/ bolt position have not worked. (These FN's have no side release like the J-9's etc)

PM'd fla3006 as the search ID'd him (by his posts) as owning some .

Any other gurus out there

fla3006 responded, thanks all.

Should have a standard Mauser bolt release like this:

Still no pics from the boy.

Though he describes getting the bolt out by a release near the trigger after my last instruction to look there.

I'm really curious now to see the pic's. Hopefully he can get to a computer.

Marlin 455 barrel on a Rem 700?

Photo of a 455 on Gunbroker, with one photo showing a bit of the normal Mauser bolt release.
