Eyeballing options for next build. I want to start with a 7.5” pistol using the law tactical folding adapter and side charging upper

Stumbled across another option though: folding/takedown barrel adapters. Anyone had any experience? The two i’m looking at are LEO and Pantheon DOLOS systems. I like the idea of hotswapping the barrel for caliber changes and keeping one lower and upper that’ll let me configure from pistol to rifle and back in seconds, rather than multiple uppers to swap (cheaper long term too to set up barrel/guard/adapter vs buying a complete upper)
