Centurion Arms produces reliable, accurate and cost effective firearms ready for a lifetime of use. Centurion Arms always produces products with longevity and hard use in mind, utilizing high quality steel for their barrels and other small components made from materials that either meet or far exceed the TDP spec. All Centurion Arms barrels are hammer forged, chrome lined, high pressure tested (HPT) and magnetic particle inspected (MPI) with a tapered bore, aiding in the overall accuracy and longevity of the barrel.
All of these upper receiver groups come with a tabbed (A unique solution from Centurion Arms to align the gas block) and pinned gas block, ready for use.
