I've had both mws and vfc rifles among other gbb platforms. I've since sold all my mws rifles and kept buying vfc . I've not had an issue with accuracy and certainly nothing that couldn't be solved by a new hop rubber if I couldn't be bothered to wear in the stock hop
The correct scope is being made by EG with the mount and acro in FDE.
The AG suppressor still looks better than the vfc one from pics but I'll directly compare them once the vfc suppressor lands later this month . UKSF versions do have some other optic and furniture options if you don't fancy...
I'm in mixed opinion as while it's nice to be cross compatible it would also be really nice if they are correct size and shape unlike normal aeg mp5 mags
