WIP: some people wanted to know how the new Acolyte arms fit on the classic Hybrids. The answer is: they do, but look a little small - unless you put some effort into it. I combined old Stealer arms with a shoulder pad of a Cadian Guardsman and the new parts.
I scratchbuilt a complete heavy bolter from parts of a new Neophyte heavy stubber and Astra Militarum grenade launcher parts as well as an old Ork boltgun (muzzle) and a Space Marine Scout's bipod. :-D
