    Default MR556 barrel reprofile at a well regarded place or 10.4 barrel at hkparts?

    Is there a general consensus on which is the best option? I noticed that the hkparts version comes with a vented gas block. I plan on running suppressed 95% of the time so not sure if that will make a difference at all. Any input would be appreciated.

    Will there be less of an accuracy loss with the hkparts barrel?

    I went the chop/thread and reprofile route, it's cheaper. The only draw for me for the HKparts barrel is the nitride inside/out coating.

    P.S. Highly recommend TommyBuilt for the MR556 upper work!

    If I were to do the reprofile it would be through IGF.

    HKParts barrel is NOT nitrided inside. First batch were nitrided in the bore, the newest ones are not nitrided in the bore, chamber, or threads.



    My 10.39" job is one of the best out there. Closest profile to HK that I know of. Completely CNC machined and Black Nitride treated. Also cheapest for what you get.

    Ive never delt with @NoScoE30 , but I hear nothing but good things about his work. I did my 14.5" via IGF and Jason did an excellent Job, but if I were to do it again I would contact NoSco.
