New to ar10 platform

[sullysbarbershopsc]

So a year ago purchased a inexpensive ar10 from cbc industries see to be ok for my uses last round hold open doesn't work but shoots with ok accuracy. I lived up north did alot of coyote hunting with a thermal so just used my ar15. This year I moved south to a place where they respect my freedoms and been do as much hog hunting as I am coyote so like to use my ar10 but the cbc industries has a 20 inch barrel lugging that around sucks like to go to shorter barrel. I did order a silencer deadair sandman s still waiting for that but with all those changes still want my gun to function properly so I have a few questions hoping you can help. Looking at a faxon barrel with a mid length gas port my cbc has rifle length, 

Will the faxon 16 barrel fit the cbc industries upper?is a new mid length gas tube and adjustable gas block work to make my gun function properly?

Or do I need to change buffer system as well?

We have no idea what buffer system you have, until you measure it all out and tell us.  Your barrel that you have will run - if you tell us the specs on the barrel that you have.

Please read this, so you understand the level of detail that necessary, in order to fix someone's gun over the internet, using their spoken words, and not firing it yourself (ourselves). 

In the past, we almost had to waterboard people for information about their gun - and it's pretty tiresome.  We stopped doing that.  You want help with your gun?  Spill details.  This link below spells out the level of detail that we need, to fix functional issues with your gun, over the internet.  Thanks in advance.  For understanding.
