Hey all. Just starting to assemble parts for my first build and
was wondering what the differences of a mid length gas system
verses a carbine gas system? Performance, parts needed, etc
thanks in advance and can't wait to start building.

Welcome to the site.

The gas port of a mid-length gas system is approximately 2" closer to the muzzle than a carbine length system.  Obviously, this moves your front sight base or gas block further forward.  Overall barrel length remains your choice or whatever is available.

Parts: Different barrel (gas port drilled closer to muzzle), gas tube (longer than carbine),and handguards(longer than carbine).  All else remains the same.
Performance: Functionally, the mid-length system is a bit more reliable.

Thanks for the info. It helps alot. I'm sure more questions will
come as this build goes along

Carbine handguards tend to be more plentiful and less expensive.  I found out my Armalite "carbine" was actually a midlength after I ordered an aftermarket handguard.  Whoops.

Do yourself a favor and get the mid-length. Much smoother 'recoil' than carbine - my .02

its all preference, i own a great carbine but i really like the feel of the mid-length sometimes I think I should have gotten one, you should try both first

Armalite calls all of their non RIFLE length rifles "carbines" because they are all carbines.  Some carbines have a true carbine length gas system and some carbines have a midlength gas system.



The only difference being the distance between chamber and gas port.  So therefore the gas tube will be longer and so will be the handguards on a midlength versus a carbine length gas system.
