Quality, Mil-Spec Components
Our kits aren't just convenient, they're equal to or greater in quality than the typical "retail rifle". We partner with some of the nation's top gunsmiths and manufacturers to carefully piece together each kit, ensuring MOA accuracy and utter reliability.
- All barrels are forged from MIL-B-11595 E steel (4150 or Chromoly Vanadium)
- All stainless barrels forged from Crucible 416R steel, offering sub-MOA accuracy
- All BCGs are M16 in profile with chrome lining and properly staked gas keys
- All stripped upper receivers forged from mil-spec 7075 T6 aluminum
- All buffer assemblies and lower parts kits are mil-spec in fit and finish
- All barreled uppers are test-fired to ensure proper assembly
Your build awaits you.
