The 223/5.56 barrels sold here are not your typical cheap OEM type barrel like PSA, Spikes, Faxon, BCA or any chrome-lined barrel. They have high performance rifling designs and chambers for better accuracy with good ammo.  62gr Gold dots, 55 Noslers, 69smks and 77gr SMKs can all shoot near 1/2MOA. 

Our goal is superior accuracy though better chamber and rifling design
ARP barrels may not be a Krieger or Bartlien but I'll put them up against any  AR15 barrel made including Noveske, Wilson Combat and Larue.

Shipping Restrictions

  • ARP will not ship ANY items to the state of California, as of Oct 1 2022 we can not sell in the state of Fl.
  • Current shipping times 3-4  BUSINESS days

Sorry we do not offer any gunsmithing services.


    DO NOT USE  bullets that are larger than .277" in these 6.8 barrels, 99.9% of all .270/6.8 bullets made are .277" diameter.  The chambers were designed for .277" bullets and all 6.8 barrels have a .277" bore so bullets larger than .277" will cause excess pressure and increased copper fouling.  It seems some Cavity Back bullets are .278" and on top of that they are solid copper so check the diameter of the bullets before using them.
