Previously these barrels were pre-threaded, which limited build options at 16". We are now receiving these with NO THREADS, allowing for full customization during building!

Examples of common step fee requests: Using a Jmac or Definitive Arms Combo Gas Block, AK-74 parts, Chopped barrel but still want to use a separate gas block and front sight (AMD-style).

*AK-74 parts will need the front sight and gas block journals extended a bit, please use the Step Fee and request via notes if you need this done.
**We will not turn down the trunnion journal from 23mm to 22mm without receiving your trunnion to ensure proper press fitment.
