The faxon gunner barre is leightweight. I love that barrel. The only deal with using leightweight bcg or carriers is it speeds up your cycling rate. So you may want to either get an adjustable gas block or a heavier buffer

I haven’t heard great things about LW BCGs. For the same reasons you mentioned and having to use heavier buffers to compensate. I always like to use an adjustable gas block
