ISO Side charger upper and 12-15" FF Handgaurd w/nut

I’m thinking about a side charging upper for a 204 hunting rifle build,and wondered if anyone had one that they tried and didn’t like,or switched out .
Not feeling a need for a door or forward assist for this build.

Also looking for a 12-15 inch hand gaurd that is either knurled round,or just a top rail. Need barrel nut with it .

I would recommend Eisensch Arms for the upper receiver and BCG. Great product and I think I got a pretty nice military discount if I remember correctly. Pretty sure I’ll build another one with this upper.
