No 5 jungle bolt

[Alan de Enfield]

Hi,

I would like to know if the Bolt head on a no5 can be change to improve headspace like no4? Is there any intercheability for no5 head? Thanks

Yes the No5 bolt (and bolt heads) for the No5 are the same as the No4, and, in some cases No4 Bolts are used on No5s.
