    I am running my AR15 with a 14.5″, Pencil Profile, Mid-Length Gas System

    Can I change it to a 16″ barrel?

    TIA

    Yes you can. Order a barrel with a pinned gas block and order an appropriate length gas tube if one does not come with the barrel. Most receivers now come with “M4” extension cuts so make sure the barrel extension has them as well or you will have feed issues. Plenty of YouTube videos on how to do the swap. Make sure to properly torque the barrel nut and use a proper receiver block so you don’t destroy your upper receiver (I use a geissele rod clamped into a good bench vice). You will need a muzzle device of your choosing as well since the one on your gun will be pinned.

    A quality barrel is worth the money. Look for chrome lined with a 556 (not 223) chamber. I have been happy with Noveske, Daniel Defence, FN, Colt, and BCM barrels.

    As already stated yes.

    Unless you plan on getting into building/working AR’s as a hobby, part of your preparations, or want personal acomplishment/satisfaction.

    I would find a quality gunsmith to do work, probably cost around $30, since buying tools needed will probably cost more.

    Not to mention I am somewhat reluctant to advise learning how without expert supervision for a fighting AR vs some plinking/target gun.

    Note: I said quality gunsmith who knows AR’s with a good reputation.

    That said if you can find someone local meeting this description, they maybe willing to let you do it under their supervision, if you are really wanting to do it yourself.

    It isn’t rocket science, but its only your life we are talking for a reliable AR to defend yourself with.

    Opinions vary. ;-)

    Is there a problem with current barrel?

    Ugh. Currently have a very loud and bright muzzle brake.

    My gun’s manufacturer obviously sells 14.5″ barrels, but without a fh, and I have no idea where to go to get one pinned and welded on. Thinking with a 16″ barrel, it would be threaded?

    Asking what courses they’ve attended helps find quality gunsmiths?

    Lastly, did I miss forum recommendations for a flash hider?

    Ain’t nothing wrong with the classic A2 flash hider.

    In today’s market it may be cheaper or close enough to just buy a new upper.

    Then you have a backup.

    At PSA I would only buy if they have FN barrels.

    The flash hider you need is the standard A2 birdcage.
