Good extended inner barrel good hop up and rubber and either a silencer or outer barrel extension.
You just swap out the inner and attach the outer extension.
Tho just by putting a good inner and hop rubber you wouldnt really need to swap back n forth. Also youll wanna check what the fps is youll likely need to downgrade the spring for indoor to 350fps and that will work fine for outdoor too
