This is what I mean!Sorry folks but I am greek
and don't know the special terms used to describe
such equipment.Now I know the term is rifled barrel.
Is this barrel useful or its just for showcasing ?
Are the advantages the same as with real rifled barrels
and up to what grade?
The price is not so high and I am thinking to install one
in my d-boys m4 if it is really better than common airsoft
